PROBLEM TO BE SOLVED: To provide a method for filling hydrogen gas into an on-vehicle storage container capable of filling a predetermined volume of the hydrogen gas into the on-vehicle storage container within a desired time frame.SOLUTION: In a method for filling hydrogen gas into an on-vehicle storage container, a hydrogen gas transfer passage (4) is branched into one hydrogen gas passage (5) with a heat exchanger (11) installed thereon to be a low temperature hydrogen gas passage and the other hydrogen gas passage (6) to be a normal temperature hydrogen gas passage. Flow control valves (9) and (10) are respectively installed on the low temperature hydrogen gas passage (5) and the normal temperature hydrogen gas passage (6) at a downstream side of a bifurcation section (7) thereof. A flow ratio of hydrogen gas flowing in the low temperature hydrogen gas passage (5) to the hydrogen gas flowing in the normal temperature hydrogen gas passage (6) is fixed by setting openings of the respective flow control valves at predetermined values. After cooling the hydrogen gas flowing in the low temperature hydrogen gas passage (5) to a boiling temperature range of refrigerant liquefied gas through heat exchange between the refrigerant liquefied gas and the hydrogen gas flowing in the low temperature hydrogen gas passage with the heat exchanger (11), low temperature hydrogen gas and normal temperature hydrogen gas is merged at the downstream side of the heat exchanger (11). Then, merged gas is filled into an on-vehicle storage container (3). |
