Abstract:

An ideal metal bipolar plate for proton exchange membrane fuel cell (PEMFC) needs good corrosion resistance and electrical conductivity. Surface modification is one of the main ways to solve the problem of corrosion resistance and electrical conductivity of metal bipolar plate for PEMFC. This paper classified, introduced and summarized various performance evaluation methods of surface modification coating on metal bipolar plate. The performance evaluation methods mainly included the electrochemical corrosion analysis, interfacial contact resistance measurements, characterization of surface topography, composition analysis and in-situ assembly of cells evaluation. It was found that the test standards were not unified and in situ evaluation methods were less used. Therefore, The research directions were put forward that the effects of test parameters need to be further analyzed to unify the test standards, and the evaluations in the real cells running environment were adopted as far as possible. It is expected that the following researches can improve the evaluation standard systems and promote the industry development orderly as soon as possible.
