PROBLEM TO BE SOLVED: To shorten the re-filling time of a hydrogen gas supply system for vehicle provided with a plurality of high-pressure hydrogen tanks. SOLUTION: A vehicle 1 is loaded with the plurality of high-pressure hydrogen tanks 2, and each of the tanks is provided with a filling valve 3, a discharge valve 4, a pressure sensor 5 and a temperature sensor 6. A vehicle control unit 13 controls the filling valve 13 and the discharge valve 4 on the basis of results of detections by the temperature sensor 6 and the pressure sensor 5. When consuming the hydrogen gas, one high-pressure hydrogen tank is selected among the plurality of the high-pressure hydrogen tanks 2, and hydrogen is supplied from the selected tank to a hydrogen consuming apparatus by priority to lower the pressure. When filling hydrogen, hydrogen is transferred to the tank, in which hydrogen is consumed by priority, from other tanks to lower temperature of other tanks. Thereafter, hydrogen is filled from a filling station 100. COPYRIGHT: (C)2004,JPO
