摘　　要：新制造的质子交换膜燃料电池(Proton Exchange Membrane Fuel Cell,PEMFC)通常需要所谓的活化过程使其它达到其额定或最佳性能。通过活化过程,可以使得其膜电极组件充分润湿,并建立有效的电子、质子、气体以及液态水的传输通道,提高了PEMFC的发电性能和稳定性。根据活化工艺的不同,这一过程可能需要数小时甚至更久的时间才能完成,并可能消耗大量的氢燃料,从而导致无法接受的时间成本和经济成本;活化工艺亟待优化。为了能够在足够短的时间内完成该活化过程,本文回顾了行业内普遍应用的活化方法,总结了关于PEMFC调节和潜在机制的可用信息,将活化类型分为四种:在线活化、离线活化、综合活化和恢复性活化。对于每种活化技术,都概述了实验程序和结果,并对PEMFC活化工艺的未来研究发展方向进行了展望。For a newly fabricated proton exchange membrane fuel cell(PEMFC)stack,a so-called activation procedure to activate it and reach its best or rated performance is imperative.Typically,during this activation period the membrane electrode assemblies can be fully wetted and efficient transport channels of electrons,protons,reactant gases and liquid water can be established,thus improved performance and stability of the PEMFC reached.Depending on the difference in activation mechanism,this activation period may take hours,even days,consuming a considerable amount of hydrogen fuel,leading to a higher operating cost;better method or conceive is urgent for optimized activation process.To shed a light on accelerated conditioning techniques that can complete the process in a shortened period,this paper reviews state-of-art conditioning protocols and reported methods to condition PEM single cells as well as stacks,in an attempt to summarize available information on PEMFC conditioning and the underlying mechanism.Various techniques are arranged into four categories:in-situ activation,ex-situ activation,combined activation and recovery activation.For each technique,the experimental procedure and outcomes are outlined.Besides,future research trend on activation process of PEMFC is proposed.
