摘  要:
主要研究运行3年的氢空质子交换膜燃料电池电堆衰退情况,通过安装在小型高尔夫球车上一个5kW燃料电池电堆进行试验分析,试验分道路试验和台架试验。试验结果表明,运行中氢空燃料电池电堆动力性能与其出厂时初始性能下降许多,最显著就是功率从5kW下降到2.5kW左右。其衰退原因众多,有质子膜的问题,电极的问题等,同时证明了必须合理保养与维护燃料电池,否则电堆容易失效,大大增加使用成本。

摘  要:
This study investigates the hydrogen-air PEMFC stack recession, whose stack has been used for three years. By installing a 5kW fuel cell stack in a golf cart, the test is done, including road test and bench test. The results indicate that the hydrogen-air fuel cell stack dynamic performance declines a lot, whose power conspicuously drops from 5kW to nearly 2.5kW, compared with that of a new one. There are many reasons of its decline, such as, the problems of proton membrane penetration and electrode destruction etc. It proves that the stack needs reasonable care and maintenance, otherwise, it tends to be easily exhaustive and thus increase costs.
