Abstract:Bipolar plate of polymer electrolyte membrane fuel cells (PEMFC) has the function of isolating reactants, collecting current and providing the channel for reaction gas. Metal bipolar materials have such problems as corrosion that decreases the performance of catalyst and forming passive film that increases the contact resistance. The research methods of metal bipolar were introduced which include interfacial resistance, polarization and mimic electrochemical testing. The performance of Fe - based alloys and light metals with different coating layers was given specially. The key technology of metal bipolar materials in PEMFC was briefly introduced.
