Study on Test and Evaluation Methods of Assembly Valve on High Pressure Hydrogen Storage Cylinder for HFCV

Abstract In this paper, a comparative study is made on the test items and evaluation criteria stipulated in the relevant regulations and standards of hydrogen storage system valves and temperature-driven pressure relief devices (TPRD) for hydrogen fuel cell vehicle (HFCV). The similarities and differences are listed and analyzed. Based on the study and according to the characteristics of the assembly valve for HFCV (hereinafter referred to as the assembly valve), some suggestions on the test items, test methods and evaluation criteria settings for the assembly valve are discussed and the test strategy for assembly valve is proposed.
