Abstract：Metal bipolar plates for proton exchange membrane (PEM) fuel cells have price and processing advantages, but easily corrode which reduces the fuel cell electrical conductivity and durability. This paper reviews recent advances related to the electrical conductivity and durability of metal bipolar plates and their coatings for fuel cells. The review starts from the market demand for PEM fuel cell stacks and the advantages of using metal bipolar plates in PEM fuel cells. Then, the typical metal bipolar plate and coating testing methods are described. Most coatings besides alloy coatings meet the US Department of Energy 2020 target. Then, this paper describes the environmental factors and working conditions that influence the plate electrical conductivity and durability. Finally, this study identifies future research prospects related to test methods, coatings research, and key factors. This paper reviews key advances in metal bipolar plates and their coatings for improving their efficiency and durability for fuel cell stacks.
