非晶合金双极板在PEMFC环境下的耐腐蚀行为

Corrosion resistance of amorphous alloy as bipolar plates in PEMFC environment

质子交换膜燃料电池(PEMFC)是一种清洁、高效的新型能源。双极板是燃料电池的关键部件之一,占据了燃料电池的主要成本和体积。在多种类型的双极板材料中,金属双极板因导电性能优异、机械强度高等优势成为传统石墨双极板的潜力替代材料,得到了广泛关注和研究。双极板的工作环境呈酸性,工作温度较高,提高金属双极板在PEMFC环境下的耐腐蚀能力仍是一个亟待解决的问题。低成本、高腐蚀耐性的非晶合金材料是近年来备受关注的双极板材料之一,对已报道的非晶材料在PEMFC环境下的耐腐蚀性研究做了全面的总结。

Proton exchange membrane fuel cells （PEMFC） is a new clean and efficient energy source. One of the key components of PEMFC is bipolar plate 9 which occupies the main cost and volume of fuel cell. Among vari-ous bipolar plates 9 metallic bipolar plates are the promising candidates compare to traditional graphite bipolar plates due to their excellent electrical conductivity and high mechanical strength. However 9 the main disadvan-tage of metals is the corrosion problem in the harsh acidic and high temperature environment inside the fuel cell. Amorphous alloys are potential materials using as bipolar plates due to their low cost and high corrosion resist-ance. This paper reviews the publications in the literature on the corrosion behavior of amorphous alloys as bipo-lar plates in PEMFC environment.
