摘要
氢燃料电池汽车(FCV)用氢气中的痕量硫化物会导致催化剂中毒,使电池的性能显著下降。各标准组织均对氢燃料电池用氢气中的硫含量做了严格的限值,要求硫化物的含量(以H_(2)S或S_(1)计)低于0.004μmol/mol,这对硫化物的分析提出了很高的要求。本文介绍了气体分析领域中各种痕量硫分析的方法和原理,比较了它们的优缺点,并对它们在FCV用氢中痕量硫分析的应用进行了探讨。
Trace sulfides in hydrogen for hydrogen fuel cell vehicles(FCV)can cause catalyst poisoning,significantly degrading battery performance.All standard organizations have made strict limits on the sulfur content in hydrogen for hydrogen fuel cells,requiring the sulfide content(in terms of H_(2)S or S_(1))to be less than 0.004μmol/mol,which puts forward high requirements for the analysis of sulfides.In this paper,the methods and principles of trace sulfur analysis in the field of gas analysis are introduced,their advantages and disadvantages are compared,and their application in trace sulfur analysis in FCVhydrogen is discussed.
