Abstract： Bipolar plates of proton exchange membrane fuel cells （PEMFC） can be classified by material into three types： graphite bipolar plates， metal bipolar plates， and composite bipolar plates. Compared with graphite and composite bipolar plates，metal bipolar plates feature advantages such as high strength， excellent electrical and thermal conductivity，easy processing，low cost， small volume， and light weight， which have attracted significant attntion from researchers. However， metal bipolar plates are prone to corrosion in the acidic and humid environment of fuel cels， forming non-conductive metal oxide films that drastically reduce the conductivity and stability of the bipolar plates. Currently， surface coating modification of metal materials is an effective approach to enhance the corrosion resistance and extend the service life of metal bipolar plates. This paper focuses on the conductivity and corrosion resistance of metal bipolar plates and their coatings，reviews the recent research progress on different types of coatings， analyzes the existing problems of bipolar plate coatings， and prospects their future development.
