中文摘要:氢燃料电池汽车用氢气中痕量杂质会影响氢燃料电池的性能,国内外标准均严格规定了痕量杂质的限值要求。离子色谱法(IC) 具有操作简单、分析快速、灵敏度高、选择性好、可多组分检测的特点,ISO 14687-2∶2012、SAE J2719∶2015和GB/T 37244-2018等标准均涉及到离子色谱法分析其中的部分指标。目前离子色谱法在环境空气、固定污染源废气、天然气、烟气等气体分析领域有广泛应用,在氢燃料杂质的分析领域尚在起步阶段。该文综述了氢燃料和其他气体分析领域中总卤化物、甲酸、氨和总硫化物的分析方法,将离子色谱与不同分析技术进行比较。并基于离子色谱在其他气体杂质分析领域的应用进展,对其在氢燃料电池汽车用氢气杂质分析中的应用作出展望。

Application Status and Prospect of Ion Chromatography in Hydrogen Detection for Hydrogen Fuel Cell Vehicles
Abstract:Trace impurities in hydrogen for hydrogen fuel cell vehicles will affect the performance of hydrogen fuel cells.The limits of trace impurities have been strictly stipulated in domestic and foreign standards.Ion chromatography(IC) has the characteristics of simple operation,rapid analysis,high sensitivity,good selectivity,and multi-component detection. The analysis of some indexs by IC were involved in ISO 14687-2∶2012,SAE J2719∶2015 and GB/T 37244-2018.At present,IC has been widely used in the field of gas analysis such as ambient air,stationary source emission,natural gas and flue gas.The analysis of hydrogen fuel impurities is still in its infancy.In this paper,the analytical methods for total halogenated compounds,formic acid,ammonia and total sulfur in hydrogen fuel and other gas analysis fields are reviewed,and IC is compared with different analytical techniques.Based on the application progress of IC in other gas impurity analysis fields,its application in hydrogen impurity analysis for hydrogen fuel cell vehicles is prospected.
