| 摘 要： | 为了研究燃料电池的耐久性,并对其衰退机理进行分析,本文在Greenlight平台上,对20片单体组成的功率为1kW的电堆在DOE循环工况下进行90h的耐久性实验.通过分析电堆在DOE循环工况下进行不同时段的电堆衰退曲线,整体的电堆衰退曲线以及电堆的极化曲线来考察电堆在DOE循环工况下的性能衰退.分析了电堆的衰退机理,并提出了自己的猜想并加以验证,得出催化剂的表面氧化造成的催化剂活性下降是引起质子交换膜燃料电堆的性能衰退的主要原因.

| Abstract: | In order to study the durability of fuel cells and analyze the mechanism of recession , the Greenlightg500 test station platform was use to test the durability of the fuel cells which is consisted by 20 pieces of fuel cell monomer with 1kW stack power in DOE cycle durability test for 90h.Throughsurvey the recession curves in different times and the Polarization curves using the DOE MEA/Stack Durability Protocol , we analysis the Mechanism of recession and raise our own hypotheses .Finally, we conclude that catalyst activity decline caused by catalyst surface oxidation state change is the main source of performance degradation of the stack . |
