摘　　要：氢作为燃料,可解决传统内燃机汽车造成的排放污染和高化石能源消耗问题。但其纯度(特别是氢中的痕量杂质)会影响催化剂的性能和燃料电池的寿命。本文整合现有分析技术标准和相关方法的无机气体和杂质氢中的总碳氢化合物,介绍了每种分析技术的工作原理、优缺点和实际研究进展,并分析每种测量方法和要求的分离度,以便系统地了解和评价技术标准和重要微量杂质的分析方法,从而获得一个合理的氢气纯度分析应用。Hydrogen as a fuel can solve the emission pollution and high fossil energy consumption problems caused by taditional internal combustion engine vehicles.The purity of hydrogen,especially the presence of trnace impuri-ties in hydrogen,will leet the performance of catalysts and the life span of fuel cells.This paper comprechensively integrales the existing analytical technical standards and related methods of inorganic gases and total hydrocarbons in impure hydrogen,and analyzes the resolutuion of each measurement method and requirement,for systematically understanding and evaluating to obain a reasonable application in hydrogen purity analysis.The working principle,ad-vantages and disadvantages,and actual rescarch prognss of each analytical technology are also elabrotely introduced.
