| Abstract: | Optimization of unhumidified membrane electrode assembly(MEA) for micro PEMFC was carried out.The optimized parameters were obtained by control of hot press condition,compositions of catalyst layer,diffusion layer material and thickness of proton exchange membrane.After combinative parameters optimization,peak power density of the MEA reached 0.166 W/cm~2 under the operating conditions of ambient temperature and pressure and no humidification for reactant gases of single micro PEMFC with MEA after optimization.No obvious performance deterioration was observed after long time continuous running. |
