| As the fourth generation of power generation technology, proton exchange membrane fuel cell (PEMFC) has absolute superiority in terms of compact structure, small size, high energy density, high efficiency, fast start, low temperature operation, and zero emission. It is considered as one of the most ideal clean energies at present, and is the ideal power component for new energy vehicles in the future, thus having received extensive attention from scholars. As one of the most important components of PEMFC, Bipolar plates not only can connect single batteries in series, parallel or series-parallel to form a battery stack and play a supporting role, but can isolate the reaction gas of cathode and anode and discharge the heat and water generated by the reaction of the battery stack, which is very important to the performance of PEMFC battery stack. Suitable bipolar plate materials with excellent electrical conductivity and corrosion resistance have become a hotspot in PEMFC research. In this paper, different bipolar plates were introduced. Graphite bipolar plate has become the traditional bipolar plate material with its excellent performance, and is currently the most studied and applied bipolar plate material. However, its high processing difficulty and high cost limit its commercial development, so it has been gradually replaced by metal bipolar plate. Compared with graphite, metal bipolar plate has higher workability. It can be ultra-thin and has a very high volume ratio power and mass ratio power. However, metal is prone to corrosion in PEMFC acidic environment and produces passivation film, which increases the contact resistance of electrode and bipolar plate surface and reduces its electrical conductivity, thereby seriously affecting the performance of battery stack. Accordingly, it is necessary to take measures to ensure its corrosion resistance and durability to prolong the service life of the battery. This paper focused primarily on the surface coating modification of stainless steel bipolar plates. The research progress and properties of a series of coatings like carbon-based coating, metal and its compound coating, conductive polymer coating and hydrophobic coating were listed and the advantages and disadvantages of these coatings in surface modification of PEMFC bipolar plates were analyzed and compared in this paper. The graphite coating has excellent properties, but its development and application are limited by high production cost and slow deposition rate. As a new material, graphene has incomparable advantages in metal bipolar plate protective coating. However, a single graphene carbon film can not achieve long-term protection for metal bipolar plates. The ideal graphene composite coating has excellent corrosion resistance and stability, and can well protect the stainless steel matrix. Transition metal carbide and transition metal nitride coatings have become the most studied coating modification materials due to their excellent performance and low production cost. The selection of protective coatings should not only consider the performance and cost of the coating itself, but also consider the binding force with the matrix and other issues. The coating modification can ensure the normal operation of bipolar plates in PEMFC operating environment, improve their corrosion resistance and conductivity, reduce production cost, and finally realize the commercial application of PEMFC. |
