Improvement of hydrogen filling capacity of hydrogen refueling stations in city area is required due to increasing number of fuel cell vehicles and for refueling fuel cell buses with large tank capacity. Since installation space area in city is limited, cryopump system is optimal for its compression efficiency and effective utilization of cold heat energy. However, cryopump system is operated under extremely low temperature and high pressure hydrogen environment. In order to select optimal material of cryopump system for hydrogen refueling stations, evaluation of hydrogen embrittlement resistance evaluation and toughness at low temperature is necessary. In this research, hydrogen embrittlement resistance and low temperature toughness of XM-19 (ASME SA479) and SUH660 (JIS G4312) were evaluated to determine their adaptability for cryopump system.
