PEMFC阴极催化剂性能的探讨

Research on the Performance of Cathode Catalyst Layer of PEMFC

依据PEMFC阴极催化剂层内氧消耗和电流生成平衡的原则 ,建立了反映阴极催化剂层性能的数学模型 ,并用实验验证了此模型的有效性 .分析了过电压、质子传导率和催化剂表面积等参数对催化剂层性能的影响 .

Mathematical model of the performance of cathode catalyst layer is developed based on the balance principle between oxygen consumption and current production in PEMFC, which is proved effective by comparing the model results with the experimental results. The influence of the over potential, proton conductivity and catalyst surface area on cathode performance is analyzed.
