The durability of membrane electrode assembly(MEA)is one of the key factors affecting the commercialization of proton exchange membrane fuel cells(PEMFC).This paper reviews the du-rability test studies of PEMFC MEA in recent years,focusing on the common accelerated stress test(AST)procedures of MEA(steady-state OCV square wave cycle,triangle sweep cycle,relative humi-dity cycle)and simulated vehicle cycle are discussed in detail.At the same time,the evaluation meth-ods and test methods of MEA characteristics,such as electrochemical analysis and physicochemical characteristics analysis are introduced,which have important guiding significance for the durability test research of MEA.
