HYDROGEN SUPPLY DEVICE

PROBLEM TO BE SOLVED: To provide a hydrogen supply device for efficiently supplying hydrogen gas to both a fuel cell as a fixed power source and a fuel cell as a mobile power source. SOLUTION: The device is provided with a reforming means 5 generating hydrogen gas by reforming source gas, a first storage means 7 storing the hydrogen gas and supplying it to a first fuel cell 2 as a fixed power source, and a second storage means 8 storing the hydrogen gas and supplying it to a second fuel 3 as a mobile power source. The storage means 8 is provided with a pressurizing means 13 pressurizing the hydrogen gas. The both storage means, 7, 8 is provided with a refining means 6 between the reforming means 5 and themselves and stores refined hydrogen gas. The storage means 7 makes hydrogen gas discharged using a hydrogen storage alloy with the use of waste heat of the reforming means 5 or the fuel cell 2. The hydrogen gas stored in the storage means 8 is pressurized to 10 to 70 MPa. It is further provided with a residual hydrogen gas detecting means 14 detecting a residual volume of the hydrogen gas in the storage means 8 and a control means 15 controlling the reforming means 5 in feedback based on the residual volume of the hydrogen gas.
