The laboratory has focused on the surface modification of metal bipolar plates for proton exchange membrane fuel cells (PEMFC) in the field of hydrogen fuel cells. We have obtained coating materials with high electrical conductivity and high corrosion resistance through material optimisation design, investigated the relevant physical mechanisms of electrical conductivity and corrosion resistance, and obtained a new integrated treatment technology for the surface gradient modification of bipolar plates. The intrinsic correlation between the composition, structure and performance of the coating materials is established, and on the basis of revealing the mechanism of electrical conductivity and corrosion, an ideal match between electrical conductivity and corrosion resistance is achieved, and a coating material formulation is designed to meet the overall performance requirements. We have established batch preparation technology and equipment for highly corrosion-resistant and long-life metal bipolar plates, which have been successfully applied to commercial products for our vehicle-mounted proton exchange membrane fuel cell power stacks. In recent years, we have started research and development on the basic scientific issues and preparation process technology of low or even non-platinum catalyst materials for fuel cells. We have published more than 40 academic papers on relevant research results, applied for more than 10 patents, granted 8 patents, transferred and transformed 5 patents, built 1 demonstration production line, and approved 2 sub-projects of the National Key R&D Program.
