In this study, the water management in alkaline anion exchange membrane fuel cells (AEMFC) by testing six kinds of carbon materials was studied, which are GDL 120, GDL120+30% PTFE, GDS310, GDS310+30% PTFE, GDL340, and GDL340+30% PTFE, respectively. The Pt/C of 0.8 mg/cm2 and with different ratios component were prepared for two catalysts as the cathode and anode electrode. In addition, the prepared Pt/C catalysts were coated on the carbon materials surface for Scanning electron microscope (SEM) testing to measure the surface and proved the Pt/C attached to the black carbon status. Then, the surface tension measuring instrument was used to measure the contact angle of each carbon material and determined the hydrophilicity/hydrophobicity of the material for further discussion of the AEMFC water management. For double verification, anion exchange membranes at different thicknesses were used to test the fuel cell discharge experiment. The results showed that one of the anode or cathode without adding hydrophobic material PTFE will cause water clogged so that the inlet gas could not smoothly pass through the electrodes and then the AEMFC performance was declined. Using hydrophobic carbon material GDL340+30% PTFE at the anode and cathode showed a better ion conductivity without flooding phenomenon. Moreover, The AEMFC with the GDL340+30% PTFE used for both anode and cathode and the FAA-3-PK-75 membrane can achieve an optimal power density of 82mW/cm2 at 0.4V whereas the AEMFC discharge test with the same types of the anode and cathode, but the other thinner FAS-30 membrane obtained a significantly high power density of 279 mW/cm2 at 0.4 V.

ABSTRACT The objectives of this research are to look into the fundamental properties of the gas diffusion layer of a PEMFC and to investigate the influence of hydrophobic treatments of gas diffusion layer on its electric conductivity. Furthermore, with an aim to thoroughly understand its functional variations, this thesis also carries out experiments to measure the changes in porosity, thickness, and electric conductivity of gas diffusion layer under various pressure levels. The gas diffusion layer, made of carbon fibers, is a kind of porous media whose structural properties depend substantially on its hydrophobic treatments. In this research, apparatus are fabricated to measure the variation of porosity due to its hydrophobic treatments. Then, measurements of the electric conductivity on the gas diffusion layer are performed under pressure load; finally SEM is adopted to investigate the structure change of fibers before and after pressure loading. The results show that the porosity of a gas diffusion layer decreases as the extent of hydrophobic treatments increases. However, under pressure load, the decrease in porosity is mitigated with the help of hydrophobic treatments because the robustness of the gas diffusion layer is enhanced by the hydrophobic treatments. Fragmentation of fibers has also been observed after pressure loading, while the electric conductivity of gas diffusion layer increases, which may attribute to the compactness of the gas diffusion layer under pressure loading. Key Words:PEMFC, Gas diffusion layer, Hydrophobic, Porosity

The time changes with each new day which in the modern science and technology, the petroleum and so on the energy material short question in the life which we comfortably facilitates, is extremely needs the urgent improvement the question. Among them, the fuel cell studies is each kind of substitution energy in at present in the choice, promotes to the present most environmental protection electricity generation way, thus the present stage receives the focal point which from all walks of life warmly focuses attention. In the fuel cell, uses all kinds of includes the hydrogen atom the fuel to carry on the response to emit the electric current, polymer electrolyte membrane fuel cell (PEMFC) the research is at present often is most studied in the present paper experiment and the discussion, because it besides has the high electric discharge potency, the zero pollution is one of reasons which it receives focuses attention on, its principle is using the hydrogen works as the fuel gas, the penetration proton exchange membrane dissociates the hydrogen ions and the electron thus discharge it, hydrogen ions with another end oxygen union, but produces the only by-product - liquid water. In the fuel cell components, the gas diffusion layer use is the gas even diffusion to the catalyst layer, causes to gas can reaction fully, but the liquid water production, can cause the gas circulation to encounter the limit to receive blocks, so studies of hydrophobic gas diffusion media and micro-porous layer in this paper changes the nature to the gas diffusion layer, can cause the gas diffusion layer the question thorough improvement which is blocked by the water, simultaneously discusses to influence overall cell performance factor of proton exchange membrane fuel cell which it to contain impregnations and sprays and so on the quantity, thickness, resistance, gas permeability, density.
