摘　　要：质子交换膜燃料电池(PEMFC)在组装好正式使用前,必须进行活化实验,这样电池才能达到并发挥其最佳性能。介绍了一种快速活化工艺,整个活化工艺时间大约2 h,活化后电堆性能大幅上升并达到稳定。通过电堆放电性能曲线、线性扫描伏安法(LSV)及循环伏安法(CV)对这种活化工艺进行验证,并与恒电流活化工艺进行对比,证实了这种快速活化工艺的有效性。The proton exchange membrane fuel cell(PEMFC)must conduct activation tests before it is assembled for use,so that it can achieve and perform its best performance.A quick activation process was introduced.The whole activation process time was about 2 h.After activation,the reactor stack performance greatly increased and reached stability.The activation process was verified by stack discharge performance curves,linear sweep voltammetry(LSV)and cyclic voltammetry(CV),and compared with the constant current activation process,confirming the effectiveness of the quick activation process.
