摘要

双极板是质子交换膜燃料电池(PEMFC)的核心部件之一，其性能优劣直接影响电池堆的输出功率和使用寿命。双极板不仅能够将单个电池连接成电池堆并提供支撑，还能提供气体流道、隔离阴阳两极，在燃料电池的工作性能和寿命方面起到关键作用。由于PEMFC 的运行环境较为苛刻，包括高温、高湿度和酸性环境，因此双极板需要具备优良的导电性能和抗腐蚀性能，以确保燃料电池的高效、稳定运行。本文简述了PEMFC 双极板的发展现状和应用进展，着重阐述了表面导电耐蚀改性方案的研究发展情况，系统介绍了不锈钢、钛及钛合金、铝合金等多种金属双极板基体的表面改性方案，对比不同金属双极板及其表面改性方案的性能特点、发展趋势和存在的问题，探讨了PEMFC 金属双极板表面改性的共性问题及发展应用前景。

Abstract

The bipolar plates are one of the core components of the proton exchange membrane fuel cell (PEMFC),and its performance directly affects the output power and service life of the battery stack.Bipolar plates not only connect individual cells into stacks and provide support,but also provide gas flow paths and isolate the anodes and cathodes, playing a key role in the operating performance and lifetime of fuel cells.Due to the harsh service environment of PEMFC, including high temperature, high humidity and acidic environment, the bipolar plates need to have excellent electrical conductivity and corrosion resistance to ensure the efficient and stable operation of the fuel cell.In this paper, the development status and application progress of PEMFC bipolar plates were briefly described.The research and development of surface modification schemes for electrical conductivity and corrosion resistance were emphatically expounded.Moreover, the surface modification schemes of stainless steel, titanium, titanium alloy, aluminum alloy and other metal bipolar plate’ substrates were systematically introduced.The performance characteristics, development trends and existing problems of different metal bipolar plates and their surface modification schemes were compared.Finally, the common problems and development and application prospects of the surface modification of PEMFC metal bipolar plates were discussed.

Key words： proton exchange membrane fuel cells; bipolar plates; surface modification; stainless steel; titanium and titanium alloys
