This review summarized the characteristics and preparation technology of metallic BPPs of fuel cells. Metal bipolar plates have many properties required for fuel cells, such as mechanical properties, thermal and electrical conductivity, and versatility. The main shortcoming of metal is its vulnerability to corrosion in the fuel cell operating environment. During this process, the formation of the passivation layer causes an unavoidable increase in the interfacial contact resistance. With an appropriate deposition method, a suitable coating system can effectively deal with this shortcoming. In this review, we summarize the classification and preparation methods of metallic BPPs coatings that are currently being studied by scholars around the world and compare the differences between the different coatings through various types of tests. It also provides relevant experience on performance test methods for fuel cell bipolar plates and the factors affecting performance and test parameters.
