摘　　要：质子交换膜燃料电池(PEMFC)具有原料清洁可再生、噪声小和理论上使用效率高等优点。然而PEMFC的使用寿命与其经济效益密不可分,有很多因素会导致寿命衰减,因此对其寿命衰减的机理分析至关重要。从PEMFC结构出发分析了其各部分的受损原因,揭示了包括大电流密度、频繁启动和停止、负载频繁变化、开路、电流纹波等各种电气特性对PEMFC使用寿命影响的机理,从电气设计角度出发总结了相应的解决方案,所进行的研究综述对提高PEMFC的使用寿命和经济效益具有一定的理论价值与指导意义。Proton exchange membrane fuel cell(PEMFC)has the advantages of clean and renewable raw material,low noise and high theoretical efficiency.However,the service life of PEMFC is inseparable from its economic benefits.There are many factors that will lead to life attenuation,so the mechanism analysis of its life attenuation is very important.Based on the structure of PEMFC,this paper analyzed the damage causes of each part of PEMFC,revealed the mechanism of the influence of various electrical conditions on the service life of PEMFC,including high current density,frequent start and stop,frequent load change,open circuit,current ripple,etc.,and the corresponding solutions were summarized from the point of view of electrical design.The research review has certain theoretical value and guiding significance for improving the service life and economic benefit of PEMFC.
