Texte intégralProton exchange membrane fuel cell (PEMC) has attracted a lot of attention in the both, laboratories and industries because PEMFC is considered as the green source of energy. Polymer electrolyte membrane (PEM) is the most important part in PEMFC owing to the fact that it is responsible for carrying protons between electrodes. Nafion® is the most commonly used polymer for PEM preparation because of its good thermal, mechanical, and chemical stability as well as high ionic conductivity. This polymer has excellent performance at low up to moderate temperatures under humidified condition. However, working at elevated temperature is more desirable and under these conditions the ionic conductivity of Nafion® membrane drops down significantly owing to the water evaporation. To obtain PEMs which can be applied at higher temperatures under anhydrous conditions, ionic liquids (ILs) are used as the proton carrier. The aim of this PhD thesis was to synthesis thermally stable and conductive ILs and use them as the additive to prepare proton conductive membranes for PEMFC application at elevated temperature.Several Pr-ILs containing different anions ([TFS]-, [TFA]-, [HS]-, [BUPH]-, and [EHPH]-based) and cations ([DETA]-, [DEPA]-, [MIM]-, and [BIM]-based) were prepared by acid-base neutralization reaction. The dynamic TGA results showed that there is a direct link between the acidity of acid and thermal stability of IL and [TFS]-based ILs demonstrated the highest thermal stability (Tdeg ~ 415−435 °C) owing to the high acidity of trifluoromethanesulfonic acid (pKa ~ -14). [TFS]-based ILs showed the highest ionic conductivity values (~ 34.5−63.7 mS•cm-1 at 150 °C) because trifluoromethanesulfonic acid is a stronger acid as compared to the other used acids for IL synthesis. According to the results, the following ionic conductivity order of studied anions can be proposed: [TFS] ˃ [HS] ˃ [TFA] ˃ [BUPH] ˃ [EHPH]. The obtained results showed that synthesized Pr-ILs have great potential to be used in PEMFC application. However, owing to the physical state of ILs, it is not possible to use them alone as the electrolyte in PEMFC. In order to have ion conductive PEM, composite membranes (polymer + IL) must be prepared.CAB/[DETA][TFS]-[DEPA][BUPH] composite membranes were prepared by a phase inversion technique. Composite membranes containing 0, 23, 33, and 41 wt.% of ILs were prepared (M0, M1, M2, and M3, respectively) by the phase inversion method. The presence of ILs in the membrane was confirmed by FTIR and EDX analysis. Thermal analysis revealed the lower thermal stability of composite membranes (Tdeg ~ 256–265 °C) in comparison with pure CAB membrane (Tdeg ~ 360 °C). Composite membranes showed good ionic conductivity (0.1–1 mS•cm-1 at 120 °C) and it was found that an increase of ILs concentration from 23 to 41 wt.% resulted in rising the membrane ionic conductivity owing to the increase of conductive regions. Furthermore, membrane ionic conductivity increased by rising the operating temperature from 25 to 120 °C owing to the ionic mobility enhancement. M3 membrane showed the highest ionic conductivity of 0.443 mS•cm-1 at 120 °C under anhydrous condition. The results prove that the fabricated CAB/[DETA][TFS]-[DEPA][BUPH] composite membranes are promising candidates for using in electrochemical applications, namely fuel cell

Texte intégralOne pivotal issue to be overcome for the widespread adoption of Proton exchange membrane fuel cells (PEMFC) is the stability overtime. In this context, This PhD project focuses on the elaboration of niobium carbide based electrocatalyst supports for the PEMFC cathode to replace the conventional carbon based supports that notoriously suffer from corrosion in fuel cell operating conditions. The approach is to associate this alternative chemical composition with controlled morphologies in order to design electronically conductive and chemically stable materials with the appropriate porosity. Three different syntheses involving hydrothermal template synthesis or electrospinning have been developed leading to three different morphologies: nanostructured powders with high surface area, self-standing nanofibrous mats, and nanotubes with porous walls. These various supports have been catalysed by deposition of platinum nanoparticles synthesised by a microwave-assisted polyol method, and they have been characterised for their chemical and structural composition, morphology, and electrochemical properties. This work demonstrates that the Pt loaded NbC supports feature a greater electrochemical stability than a commercial Pt/C reference and similar electrocatalytic activities towards the oxygen reduction reaction

Texte intégralConventional electrocatalysts used in proton exchange membrane fuel cells (PEMFC) are composed of platinum nanoparticles supported on high specific surface area carbon blacks. At the cathode side of the PEMFC, where the oxygen reduction reaction (ORR) occurs, the electrochemical potential can reach high values - especially during startup-shutdown operating conditions - resulting in irreversible degradation of the carbon support. A “material” solution consists of replacing the carbon with supports based on metal oxides. The latter have to be resistant to electrochemical corrosion, be electronic conductor and have a porous and nano-architectural structure (for the transport of reagents and products and the homogeneous distribution of the ionomer and platinum nanoparticles).In this work, we have developed and characterized electrocatalysts composed of platinum (Pt) nanoparticles based on tin dioxide (SnO2) and titanium dioxide (TiO2) with optimized textural (aerogel, nanofibres or loosetubes morphologies) and electron-conduction properties (doped with niobium Nb or antimony Sb). The best electrocatalytic properties are reached for an antimony-doped SnO2 aerogel support, denoted ATO. The Pt/ATO electrocatalyst has especially a higher specific activity for the ORR than a Pt/carbon Vulcan® electrocatalyst, synthesized in the same conditions, suggesting beneficial interactions between the Pt nanoparticles and the metal oxide support (Strong Metal Support Interactions SMSI).Durability tests simulating automotive operating conditions of a PEMFC were carried out in liquid electrolyte at 57 °C on these two electrocatalysts by cycling between 0.60 and 1.00 V vs the reversible hydrogen electrode (RHE) or between 1.00 and 1.50 V vs RHE. The Pt/ATO electrocatalyst has an increased stability compared to the reference Pt/carbon Vulcan® electrocatalyst. However, new degradation mechanisms were highlighted in this study: first, the doping element (Sb) is progressively dissolved during electrochemical ageing, which implies a loss of electronic conductivity. This loss is partly due to incursions at low potential, including during electrochemical characterizations. Moreover, between 5,000 and 10,000 cycles of the accelerated stress tests (between 0.60 and 1.00 V vs RHE or between 1.00 and 1.50 V vs RHE at 57 °C), the support loses its porous structure and forms a poorly conductive amorphous film

Texte intégralThe Proton Exchange Membrane Fuel Cell (PEMFC) is an electrochemical converter that produces electricity, heat and water from the oxidation of hydrogen and reduction of oxygen. This efficient and greenhouse gas-free technology is a promising candidate for reducing CO2 emissions, particularly in heavy-duty transportation applications (trucks, buses, etc.). Catalyst layers are the seat of electrochemical reactions and thus the electrodes of the PEMFC. They determine the performance, cost and durability of the fuel cell. Catalyst layers are porous layers composed of nanostructured catalyst particles bound by a proton-conducting polymer, the ionomer. The catalyst layer is obtained by drying, after coating, an ink consisting of a dispersion of catalyst particles and ionomer in one or more solvents. It has been shown that the performance of the catalyst layer depends on manufacturing parameters such as catalyst layer composition, ink solvent type, deposition and assembly process with other PEMFC components. In this work, the structural characterization of the ionomer in the catalyst layer will provide a better understanding of the relationships between its fabrication and operation

Texte intégralFuel cells (FC) are powerful systems for electricity production. They have a good efficiency and do not generate greenhouse gases. This technology involves a lot of scientific fields, which leads to the appearance of strongly inter-dependent parameters. It makes the system particularly hard to control and increase the fault’s occurrence frequency. These two issues underline the necessity to maintain the expected system performance, even in faulty condition. It is a so-called “fault tolerant control” (FTC). The present paper aims to describe the state of the art of FTC applied to the proton exchange membrane fuel cell (PEMFC). The FTC approach is composed of two parts. First, a diagnostic part allows the identification and the isolation of a fault. It requires a good a priori knowledge of all the possible faults in the system. Then, a control part, where an optimal control strategy is needed to find the best operating point or to recover the fault
