PROBLEM TO BE SOLVED: To fill hydrogen into hydrogen storage alloys in a state that hydrogen storage alloys are mounted on a vehicle by selectively operating each of a cooling means when hydrogen is filled into hydrogen storage alloys mounted on a vehicle and a heating means when hydrogen is desorbed from hydrogen storage alloys. SOLUTION: When hydrogen is filled, a connection port 13 is connected with piping 12 of a hydrogen cylinder 11 and a valve of the hydrogen cylinder 11 is opened. At the same time as the opening, a change-over valve 35 is switched, piping 65 and a heat exchanger 37 are communicated, a cooling fan 70 is driven and the heat exchanger 37 is air-cooled. At this time, also hydrogen storage alloys are cooled by cooling water within a water circulating system 30 by the heat exchanger 37 and hydrogen is absorbed. After a heater 41 is turned on, the change-over valve 35 is switched, the piping 65 and a bypass 39 are communicated and a temperature of the water circulating system 30 is raised when hydrogen is desorbed, an opening and closing means of a hydrogen supply system of a fuel cell is opened, hydrogen storage alloys are heated by circulating water and hydrogen is desorbed. |
