ANALYSIS METHOD STUDIES OF TRACE SULFIDES IN HYDROGEN FUEL FOR PEMFC VEHICLES
In this paper,a method for analysis of trace sulfides in hydrogen fuel for PEMFC vehicles based on the online gas diluter,low temperature enrichment device and gas chromatography with sulfur chemiluminescence detector was established.The results show that under the optimal experimental conditions including focusing temperature,stripping temperature,injection flow and injection volume,the established method is with the linear correlation coefficient R2>0.9995,detection limit of 0.0030-0.0066 nmol/mol,recovery of 95%-105%,repeatability limit of 0.036-0.070 nmol/mol,and reproducibility limit of 0.048-0.080 nmol/mol,which meets the analysis requirements of the trace sulfur in hydrogen fuel for PEMFC vehicles.
