用全氟磺酸质子交换膜作为质子交换膜燃料电池(PEMFC) 电解质,简化了水和电解质的管理.本文研究了该燃料电池质子交换膜厚度对电池性能影响;性能最佳的Nafion 112 膜和低铂载量E_TEK 电极组装的PEMFC,最大输出功率高达0-95 W/cm2 ;同时考察了电池的能量转换效率、E_TEK 电极中铂电催化剂利用率和电池的稳定性
Proton_exchange membrane fuel cells(PEMFC) using a perfluorosulfonic acid proton exchange membrane as an electrolyte can simplify water and electrolyte management.In this paper,the effects of thickness of PEM on the performance of PEMFC were studied.The Nafion_112 PEM and low platinum loading E_TEK electrode yielded very high power density,of the order of 0.95 W/cm 2.The energy_conversion efficiency,the degree of platinum utilization and stability for PEMFC using Nafion 112 and E_TEK electrode were also investigated.
