HYDROGEN CHARGING METHOD AND HYDROGEN CHARGING DEVICE TO PRESSURE HYDROGEN TANK

摘要

PPROBLEM TO BE SOLVED: To provide a hydrogen charging method and a hydrogen charging device to a pressure hydrogen tank in which hydrogen storage pressure can be lower, in which installation space can be smaller, and in which energy loss can be reduced. PSOLUTION: This hydrogen charging device 1 for charging hydrogen to the pressure hydrogen tank 50 is provided with hydrogen supply tanks 5 and 6 to store hydrogen under pressure, a storage part 11 provided with hydrogen storage alloy, gas flow passages 27-30 for connecting the hydrogen supply tanks 5 and 6 to the pressure hydrogen tank 50, and the storage part 11 to the pressure hydrogen tank 50, and a heater part 12 connected to the hydrogen supply tanks 5 and 6 through gas flow passages 23, 24, and 26, and having hydrogen storage alloy for heating by storing hydrogen. The hydrogen storage alloy in the storage part 11 is heated by the heater part 12. PCOPYRIGHT: (C)2005,JPO&NCIPI
