摘　　要：双极板是燃料电池的核心部件,其性能直接影响电池的效率、寿命和成本。随着燃料电池技术在汽车领域的迅速发展,双极板的研究备受关注。目前,主要研究的双极板材料包括金属、复合材料和石墨双极板。金属双极板因高导电性和机械强度成为热点,但需通过表面处理提升耐腐蚀性。复合材料双极板通过复合结构设计实现性能优化,碳基复合材料和金属-非金属复合材料在导电性和耐腐蚀性方面表现优异。石墨双极板以其优异导电性和耐腐蚀性,适用于高温环境,但脆性和加工难度较高。本文综述了各类双极板材料的最新研究成果,分析其优缺点及应用前景,并对未来车用燃料电池双极板材料的发展提出建议。The bipolar plate is an important material for fuel cell performance,affecting efficiency,lifespan,and cost.As fuel cell technology advances in the automotive industry,interest in bipolar plate materials grows.Research focuses on metal,composite,and graphite plates.Metal plates,like stainless steel and titanium,offer good conductivity and strength but need surface treatments for corrosion resistance.Composite plates combine metal and non-metal materials for optimized performance,while graphite plates provide excellent conductivity and corrosion resistance but are brittle and hard to process.This review outlines recent research,advantages,challenges,and future directions for fuel cell bipolar plates in automotive applications.
