Abstract

As one of the important components of PEMFC, the performance of the bipolar plate seriously affects the working efficiency and service life of the fuel cell. Metal bipolar plates are prone to corrosion after long-term operation, which contaminates the proton exchange membrane and leads to an increase in membrane resistance and reduces the performance of the proton exchange membrane fuel cell. In this paper, the preparation process and materials of bipolar plate coatings for automotive fuel cells are discussed in depth. The characteristics and applications of different preparation methods are elaborated in detail, and the properties and applications of various coating materials are analyzed. The study shows that the study of efficient and low-cost preparation process and high-performance coating materials is the key to improve the performance of automotive fuel cell bipolar plates, which is of great significance for promoting the commercial application of fuel cell vehicles.
