摘　　要：对微型质子交换膜燃料电池(PEMFC)的非增湿膜电极(MEA)制备工艺进行了优化研究。通过对热压条件、催化层组分、扩散层材料及质子交换膜的厚度等的控制,获得了综合优化参数。采用优化后的MEA组装单体微型PEMFC,在常温、常压及反应气体非增湿的条件下,MEA的峰值功率可达0.166 W/cm2,MEA长时间运行性能未见明显衰减。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 PEM- FC with MEA after optimization. No obvious nerformance deterioration was observed after long time continuous running.
