Current status and prospect of durability testing technology for membrane electrode assemblies in fuel cells
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.
