PROBLEM TO BE SOLVED: To continuously supply hydrogen from a plurality of hydrogen storage tanks in a simple structure and call attention in filling hydrogen by displaying the remainder of the hydrogen. SOLUTION: Open/close valves 21-2n are provided at inflow/outflow ports of hydrogen storage tanks MH1-MHn and a pressure sensor 48 is mounted on a hydrogen supply pipe 44 connected to the inflow-outflow ports via communication pipes 41. When a pressure from the pressure sensor 48 is a threshold value or lower, the open/close valves 21-2n are open/closed to switch the hydrogen storage tanks in sequence. At this time, a value for a remainder scale 95 is decreased for displaying the remainder of hydrogen. The hydrogen storage tank into which the hydrogen is supplied via a temperature control device 50 and the hydrogen storage tank into which the hydrogen is to be supplied next are heated. The hydrogen can be continuously supplied into the hydrogen storage tanks which are already heated when switched. |
