中文摘要:
      双极板是质子交换膜燃料电池(Proton exchange membrane fuel cell,PEMFC)的关键部件,对燃料电池的寿命、成本及性能具有重要影响。相比于石墨双极板和碳基复合材料双极板,金属双极板体积小、强度高、导电性能优异,已成为PEMFC双极板的主流材料。然而金属双极板易在PEFMC两极环境中产生腐蚀,且极板表面生成的氧化膜会降低其导电性,严重阻碍了金属双极板的进一步应用。从金属双极板基材选材、涂层结构设计及其性能等方面综述了金属双极板表面改性研究进展,特别探讨了金属双极板金属基涂层(贵金属、金属碳/氮化物、合金等)和碳基涂层(石墨、导电聚合物、无定型碳等)的最新研究成果,从涂层的膜基结合强度、耐蚀性、导电性和疏水性等方面探讨了现有涂层的优劣,涂层结构复合和纳米化有助于提升涂层的致密性,同时可进一步提升涂层导电性和耐蚀性。如何降低金属双极板材料和表面改性成本,提高极板耐蚀性、导电性和可靠性成为双极板研究的趋势,其对PEFMC性能提升和产业化推进具有重大意义。
英文摘要:
      Bipolar plate (BP) is the key multifunctional component in proton exchange membrane fuel cell (PEMFC) and has significant influence on the service life, cost and performance of PEMFC. Compared with graphite and carbon-based composite bipolar plates, metal bipolar plate has become the mainstream material of BP due to small volume, high strength and excellent electrical conductivity. However, metal BP are prone to corrosion in the environment of PEFMC, and the oxide film generated on the surface of metal BP reduce its electrical conductivity, which seriously hinders the further application of the metal BP. The research progress of surface modification in metal BP was explored from aspects of material selection, coating structure design and characteristics. Furthermore, the latest results of metal-based coatings (precious metals, metal carbon/nitrides, alloy, etc.) and carbon-based coatings (graphite, conductive polymers, amorphous carbon, etc.) on metal BP were discussed especially. Moreover, the performances of various coatings were valued according coatings binding strength, corrosion resistance, electrical conductivity and wettability. Coatings with multilayer composite and nanoscale structure could improve its denseness, conductivity and corrosion resistance. Obviously, how to reduce BP’s cost and improve the corrosion resistance, electrical conductivity and reliability of BP becomes the research trend of BP and has a significant impact on performance improvement and industrialization of PEMFC.
