<P>PROBLEM TO BE SOLVED: To provide an apparatus and method for supplying fuel hydrogen gas for filling an on-vehicle hydrogen filling tank of a vehicle with hydrogen gas in a short time. <P>SOLUTION: The fuel hydrogen gas supply method includes the steps of: pressurizing liquid hydrogen introduced from a liquid hydrogen storage container 1; introducing the pressurized liquid hydrogen into a heat exchanger 3 to vaporize the liquid hydrogen; and filling the on-vehicle hydrogen filling tank with the hydrogen gas introduced from the heat exchanger 3, through a filling nozzle 6. Flow control valves 4, 9, 16 disposed in hydrogen supply lines 7, 8, 15 are controlled to be opened/closed to adjust a mixed gas temperature to a target temperature. The mixed gas is made by mixing the low-temperature gas flowing in a hydrogen supply bypass line B formed to bypass at least a part of the heat exchanger 3 and the flow control valve 4, and vaporized normal-temperature gas passing through the heat exchanger 3 and flowing in the hydrogen supply line 7. <P>COPYRIGHT: (C)2012,JPO&INPIT |
