Abstract (sommario):

Over the last several years, significant developments have been made in bilayer electrolytes (e.g. GDC(Ce0.9Gd0.1O2-δ)/ESB((Er0.20Bi0.80O1.5)) suitable for low-temperature operating solid oxide fuel cells (SOFCs). Such bilayer electrolytes offer the potential for developing high performing LT-SOFCs by lowering the ohmic area specific resistance (ASR), and by improving the open circuit voltage (OCV) of mixed ionic/electronic conducting (MIEC) type electrolyte (e.g., GDC). However, optimizing the thickness ratio of the bilayer electrolyte is essential to achieve high power densities at low-temperatures (650-500 ℃). Here, we made a systematic study by varying the thickness ratios between GDC and YCSB((Bi0.75Y0.25)1.86Ce0.14O3±δ) bilayer electrolytes on an anode-supported LT-SOFCs, in all cases, the maximum power density (MPD) of the bilayer electrolyte cells is higher than pristine GDC based cells with reduced ohmic ASR values. Specifically, a high MPD of ~1 W/cm2 at 650 ℃ was achieved on a GDC(20μm) / YCSB(12μm) bilayer electrolyte based SOFC, which is 62% higher than pristine GDC based SOFC (0.64 W/cm2) operating on humidified H2 as fuel. Such enhancement is due to the 9.3% improvement in OCV (from 0.791 to 0.865 V) and a considerable 36% reduction in ohmic ASR values (from 0.094 to 0.069 Ω.cm2). Such reduction in ohmic ASR of the GDC/YCSB bilayer electrolyte SOFCs is due to the increase of GDC electrical conductivity as a result of lower pO2 at the interface of YCSB and GDC, and hence, must be considered in optimizing the thickness ratio of the bilayer electrolyte for achieving higher power density SOFCs.

Abstract (sommario):

To examine the effects of membrane charge, the electrolyte species and glycosyl on the distribution of negatively charged radical of superoxide anion (·O2−) around the cell membrane, different phospholipid bilayer systems containing ·O2− radicals, different electrolytes and phospholipid bilayers were constructed through Charmm-GUI and Amber16. These systems were equilibrated with molecular dynamics by using Gromacs 5.0.2 to analyze the statistical behaviors of ·O2− near the lipid membrane under different conditions. It was found that in the presence of potassium rather than sodium, the negative charge of the phospholipid membrane is more likely to rarefy the superoxide anion distribution near the membrane surface. Further, the presence of glycosyl significantly reduced the density of ·O2− near the phospholipid bilayer by 78.3% compared with that of the neutral lipid membrane, which may have a significant contribution to reducing the lipid peroxidation from decreasing the ·O2− density near the membrane.

Abstract (sommario):

We present an approach for integrating a thin-film bilayer combination comprising a Ni(O)-YSZ nanocomposite layer and a YSZ thin-film electrolyte prepared using pulsed laser deposition into the architecture of porous Ni-YSZ-supported cells. Achieving a minimum bilayer thickness threshold of ~1.5 µm is found to be critical to achieve a high open circuit voltage value, as well as a significant decrease in the ohmic resistance to ~0.06 Ωcm2 at 750 °C and increase in maximum power density to 1.83 W/cm2. Short-term durability tests up to 45 h at a constant potential of 0.8 V showed stable operation with current densities reaching ~1.7 A/cm2. Cells utilizing thin-film bilayers can overcome issues associated degradation in conventionally sintered cells, in terms of maintaining excellent contact with the anode support and significantly suppressing Ni diffusion into the YSZ electrolyte.

Abstract (sommario):

Protonic ceramic fuel cells (PCFCs) are promising devices for highly efficient next-generation fuel cell systems. PCFCs provide several benefits. Water formation at the cathode can improve fuel utilization. Also, lowering operation temperature using proton-conducting solid electrolyte membranes will enable a long lifetime and low system costs. On the other hand, ionic and electronic transport properties, i.e., proton, oxide ion, hole, and electron conductions, in PCFCs induce leakage current in electrolyte membranes and decrease energy conversion efficiency. Therefore, controlling the transport properties and designing cell structures to prevent them are important issues for developing highly efficient PCFCs. In this study, a comprehensive design approach was conducted from a bilayer cell to a PCFC system. It has been reported that bilayer electrolytes can improve the interface between cathode and electrolyte and also prevent nickel diffusion (1). Additionally, it has been reported that bilayer electrolytes can suppress leakage current by using a hole blocking layer (2, 3). Therefore, the use of bilayer electrolytes can help improve the efficiency and performance of PCFCs. In this study, a bilayer PCFC consisting of BaZr0.8Y0.2O3−δ (BZY) and BaZr0.1Ce0.7Y0.1Yb0.1O3−δ (BZCYYb) was modeled by considering the transport properties of each electrolyte. The main objective of the modeling was to determine the best cell design and operating conditions that maximize PCFC efficiency. Calculations were done by solving the set of integral equations described by Choudhury and Patterson (4) but extended for bilayer electrolytes (3) to obtain the cell potential, and the total and proton current densities. It was found that higher efficiencies were obtained when using a thin layer of BZY with a thicker layer of BZCYYb. The calculations suggest that the thin BZY layer acts as an electron-blocking layer. For example, leakage currents of less than 5% can be achieved by using a BZY(1 µm)|BZCYYb (19 µm). It was also found that the PCFC efficiency increased with decreasing temperature. Thus, higher efficiencies were obtained at 500°C than at 600°C. In addition, the energy conversion efficiency of a 5kW(DC)-class PCFC system was evaluated. In this study, the fuel in an anode was assumed to be hydrogen obtained by steam reforming of methane. Gas compositions in the streams of the PCFC system were calculated based on thermodynamic equilibrium at atmospheric pressure. The operating temperature of PCFC module was set as 500°C-600°C, and the external current density was assumed to be 300 mA/cm2. Here, the leakage current ratio was defined as a percentage of the leakage current to the total ion current density. The system efficiency was defined as an extracted power of the PCFC to the combustion heat of methane (25°C, LHV). The results are described as a standard case of 600°C as follows. A system efficiency of 69.5％ (LHV, DC) was attainable, assuming the cell voltage of 0.85 V, leakage current ratio of 1%, and fuel utilization of 94.2％. In this case, the steam-to-carbon ratio (S/C) was 2.5. In addition, a system efficiency of over 70％ (LHV, DC) was obtained under the cell voltage of 0.9 V, leakage current ratio of less than 5%, and fuel utilization of over 90％. Based on the above results, a cell design with bilayer electrolyte was discussed considering electrode/electrolyte materials and physical properties (e.g., transport number and conductivity).

Abstract (sommario):

A highly efficient power generation system was designed by minimizing leakage current in protonic ceramic fuel cells (PCFCs) using bilayer electrolytes. The best electrolyte designs are achieved by optimizing the cell efficiency based on the transport properties of electrolyte materials assuming hydrogen as fuel. In parallel, the effect of the electrodes on the overall cell performance was also considered. Additionally, a PCFC system was modeled using the designed cells. Two PCFC systems were investigated. One based on hydrogen as a fuel, and another based on methane as fuel. It was found that a bilayer electrolyte consisting of BaZr0.8Y0.2O3−δ (BZY) with a thin layer of lanthanum tungstate (La28-xW4+xO54+3x/2v2-3x/2) is the most effective at reducing leakage current at 600°C. For this cell, a system efficiency of 69% (LHV, DC) and 65% (LHV, AC) were obtained under the cell voltage of 0.93 V, with a leakage current ratio of less than 1%, and fuel utilization of 95% when using hydrogen as fuel. On the other hand, when methane was used as fuel, the efficiency increased up to 78% (LHV, DC) and 74% (LHV, AC).

Abstract (sommario):

Yttria-stabilized zirconia (YSZ) is the most popular electrolyte material for solid oxide fuel cells (SOFCs). However, when cobaltite-based perovskite cathode materials, for example lanthanum strontium cobalt ferrite (LSCF), are used, an insulating layer is easy to be formed at the cathode-electrolyte interface. For preventing the interfacial reaction, a gadolinium-doped ceria (GDC) interlayer is usually employed between YSZ and cathode. In this work, we investigated the fabrication of YSZ/GDC bilayer electrolyte thin films by a simple spray coating process and co-sintering. Dense YSZ/GDC bilayer electrolyte thin films were successfully fabricated. There is no crack and delamination observed for the YSZ/GDC bilayer. A Ni-YSZ/YSZ/GDC/LSCF-GDC anode-supported single cell with 4 µm thick YSZ layer and 2 µm thick GDC layer shows an open-circuit voltage of 1.1 V and a maximum power density of about 0.6 W/cm2 with humidified H2 as fuel and air as oxidant at 700°C.

Abstract (sommario):

In this work, we report a highly dense GDC/YSZ bilayer electrolyte prepared via cost-competitive method, at a relatively low sintering temperature. An ultra-thin and dense GDC barrier layer is grown on the surface of as-sintered YSZ electrolyte by twice successive in-situ hydrothermal growth at 180 oC. The GDC/YSZ bilayer electrolyte is successfully fabricated under low sintering temperature below 1200 oC, with overall layer as thick as ~540 nm and ultra-high density as the YSZ electrolyte. The anode supported single cell with LSCF cathode shows maximum power density of ~0.961 W/cm2 at 780 oC. Moreover, the cell runs stably at 720 oC for 300 hours, showing decent durability.

Abstract (sommario):

Les propriétés de conduction de la zircone stabilisée à l’yttrium (YSZ) imposent des températures de fonctionnement supérieures ou égales à 700 °C pour les piles à combustible à oxyde solide (SOFC, Solid Oxyde Fuel Cell en anglais). De très bonnes performances ayant été reportées dans la littérature sur les cellules à électrolytes bicouches à base de cérine dopée au gadolinium (GDC) et d’oxyde de bismuth partiellement substitué à l’erbium, dans cette étude, nous avons repris ce concept dans l’objectif d’élaborer une cellule complète. Dans un premier temps, les conditions de dépôt d'une couche mince (< 5 µm) d’oxyde de bismuth de composition Er0.5Bi1.5O3 (ESB) sur un substrat dense de (GDC) ont été optimisées. L’enduction par centrifugation (Spin Coating en anglais) a été retenue comme technique de dépôt. La composition d’une encre à base d’éthanol a été optimisée et permis l’obtention de couches denses, sans fissure, d’épaisseur contrôlée de quelques microns. Un composite La0.6Sr0.4MnO3/ Er0.5Bi1.5O3 (La0,6/ESB) a été retenu comme matériau de cathode. Après optimisation de ses conditions de dépôt par sérigraphie et caractérisation par spectroscopie d’impédance sur des cellules symétriques constituées d’un électrolyte d’ESB, des cellules complètes ont été préparées par dépôt d’une couche dense d'ESB sur des demi-cellules supportées par une anode avec GDC comme électrolyte, d’une part, et une anode avec YSZ comme électrolyte, d’autre part. Si la fragilité des cellules à base de cérine n’a pas permis de mesurer leurs performances, l’étude confirme des performances accrues pour la cellule Ni-YSZ|YSZ|ESB|ESB-La0,6|La0,6 comparée à la même cellule sans couche ESB
The conduction properties of yttrium-stabilized zirconia (YSZ) require operating temperatures of 700°C or higher for solid oxide fuel cells (SOFC). Very good performances were reported in the literature on bilayer electrolyte cells based on gadolinium-doped ceria (GDC) and bismuth oxide partially substituted with erbium. In this study, we considered this concept in order to develop a full cell. First, the conditions for the deposition of a thin layer (< 5 µm) of bismuth oxide of Er0.5Bi1.5O3 composition (ESB) on a dense substrate of (GDC) were optimised. Spin coating was chosen as the deposition technique. The composition of an ethanol-based ink was optimised and allowed to obtain dense layers, without crack, with a controlled thickness of a few microns. A La0.6Sr0.4MnO3/ Er0.5Bi1.5O3 (La0.6/ESB) composite was selected as cathode material. After optimisation of its deposition conditions by screen printing and characterisation by impedance spectroscopy on symmetrical cells made of an ESB electrolyte, full cells were prepared by deposition of a dense layer of ESB on half-cells supported by an anode with GDC as electrolyte, on the one hand, and an anode with YSZ as electrolyte, on the other hand. While the fragility of the ceria-based cells did not allow their performance to be measured, the study confirmed increased performances for the Ni-YSZ|YSZ|ESB|ESB-La0.6|La0.6 cell compared to the same cell without ESB layer

Abstract (sommario):

Because of unique electrical properties of graphene, it has been employed in many applications, such as batteries, energy storage devices and biosensors. In this chapter modelling of bilayer graphene nanoribbon (BGNR) sensor is in our focus. Based on the presented model BGNR quantum capacitance variation effect by the prostate specific antigen (PSA) injected electrons into the FET channel as a sensing mechanism is considered. Also carrier movement in BGNR as another modelling parameter is suggested. PSA adsorption and local pH value of injecting carriers on the surface of player BGNR is modelled. Carrier concentration as a function of control parameters (f, p) is predicted. Furthermore, changes in charged lipid membrane properties can be electrically detected by graphene based electrolyte gated Graphene Field Effect Transistor (GFET). In this chapter, monolayer graphene-based GFET with a focus on conductance variation occurred by membrane electric charges and thickness is studied. Monolayer graphene conductance as an electrical detection platform which is tuned by neutral, negative and positive electric charged membrane together with membrane thickness is suggested. Electric charge and thickness of the lipid bilayer (QLP and LLP) as a function of carrier density are proposed and the control parameters are defined. Finally, the proposed analytical model is compared with experimental data which indicates good overall agreement.

Abstract (sommario):

Ceramic fuel cell, such as solid oxide fuel cell (SOFC), usually has three functional layers with one dense electrolyte in the middle and two porous electrodes on each side of it, which operates around 1000°C. Recent research activities in SOFC tend to lower the operation temperature to the range of 700°C-800°C due to improvement in mechanical properties, and reduction in costs. However, the state-of-the-art electrolyte yttria-stabilized zirconia (YSZ) under this reduced temperature produces relatively poor ionic conductivity. Ceria-based electrolyte is an excellent candidate in electrical properties under intermediate temperature range, even though it shows a lattice expansion by cerium reduction at the very low oxygen partial pressure occurring at the anode side. Hence, a bilayer yttria doped ceria (YDC) with thin YSZ protection at anode side is designed to maximize the ionic conductivity. However, this lattice expansion of cerium results in an internal stress under this SOFC consideration. In this paper, oxygen partial pressure dependent creep behavior of an edge crack at the bi-material interface (YSZ:YDC) is studied numerically. The steady state C* path independent integral is obtained from ABAQUS code. Bi-material and homogeneous cases are discussed under extensive creep. Finally, fracture analysis of an edge crack at the bilayer electrolyte is also investigated for homogeneous bilayer materials.

Abstract (sommario):

Conducting polymer actuators and sensors utilize electrochemical reactions and associated ion transport at the polymer-electrolyte interface for their engineering function. Similarly, a bioderived active material utilizes ion transport through a protein and across a bilayer lipid membrane for sensing and actuation functions. Inspired by the similarity in ion transport process in a bilayer lipid membrane (BLM) and conducting polymers, we propose to build an integrated ionic device in which the ion transport through the protein in the bilayer lipid membrane regulates the electrolytic and mechanical properties of the conducting polymer. This article demonstrates the fabrication and characterization of a DPhPC planar BLM reconstituted with alamethicin and supported on a polypyrrole bridge measuring 100 μm × 500 μm and formed across micro-fabricated gold pads. The assembly is supported on silicon dioxide coated wafers and packaged into an electronic-ionic package for electrochemical characterization. The various ionic components in the integrated ionic device are characterized using electrical impedance spectroscopy (EIS), cyclic voltammetry (CV), and chronoamperometry (CA) measurements. The results from our experimental studies demonstrate the procedure to fabricate a rugged electro active polymer supported BLM that will serve as a platform for chemical, bioelectrical sensing and VOC detection.

Abstract (sommario):

Irreversible electroporation (IRE) is a method to kill cells by exposing the cell to intense electric field pulses[1]. It is postulated that the lipid bilayer rearranges to create permanent defects in the cell membrane which eventually leads to cell death via necrosis[1]. We postulate that the recurrence of cancer for patients treated for the disease would be minimized if their blood was monitored using a microdevice which would destroy existing or new exfoliated cancer cells. Dielectrophoresis (DEP) is the motion of polarizable particles that are suspended in an electrolyte when subjected to a spatially nonuniform electric field [2]. Insulator-based DEP uses insulating structures rather than electrode arrays to produce the nonuniform fields needed to drive DEP. We hypothesize that iDEP can enable the selective IRE of a particular cell type within a microfluidic platform. This manuscript demonstrates through modeling the feasibility of coupling iDEP with IRE using an AC field with a DC offset. Such a platform could be used to selectively destroy isolate cancer cells while not affecting normal cells.

Abstract (sommario):

Abstract A statistical mechanical model of pore formation in lipid bilayer membranes due to thermal fluctuations is coupled with a model of diffusion in pores to obtain predictions of cell membrane permeabilities to a variety of molecules. Predictions of pore size distributions in the cell membrane, as well as activation energies for transmembrane transport, are obtained for water, glycerol, and electrolytes, in a wide range of cell types. A good correlation between theoretical predictions and experimental data from the literature indicates that diffusion through transient bilayer pores may be an important cause of increased membrane permeability in thermally stressed cells.
