| 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. |
