| Abstract: | Due to its unique electrical conductivity and electrochemical properties, polyaniline has become an important material for bipolar plate protection along with the development of fuel cells in recent years. However, the long-term corrosion resistance of the polyaniline coating under the high temperature and strong acid working environment of the proton exchange membrane fuel cell still cannot meet the requirements, which limits its large-scale application. This article reviews the latest research progress on the application of polyaniline-based coatings on bipolar plates for proton exchange membrane fuel cells, including the polyaniline coating modified by doping and copolymerization, and the polyaniline-based composite coating with the introduction of polymer materials and nanomaterials. The electrochemical test and performance results of various typical coatings are analyzed, and the corrosion resistance mechanism of polyaniline-based composite coatings is discussed. Finally, the current problems in the research of polyaniline-based coatings are summarized, and the direction of research and development is prospected. It is pointed out that the test standard should be consistent which has great significance for material performance evaluation and commercial application. Furthermore, the research on nano-material composite coatings should be strengthened in the future and the analysis of the coating mechanism in depth should be based on in-situ observation and characterization technology. |
