PURPOSE: To prevent drop in the releasing amount of hydrogen in low temperature starting by arranging a heat generating body which generate heat by chemical reaction in part of a hydrogen storage alloy tank. CONSTITUTION: A heat generating body container A (51) in which a heat generating body 5 is housed is fixed to an end (17) on opposite side to an opening 13 of a hydrogen storage alloy tank 11 (18) nearest to a hydrogen gas suction pipe 15. The heat generating body container A (51) is a cylindrical container with almost the same diameter as a first tank (180 and whose both ends are closed, and a bottom surface is attached to a heat generating body container attaching surface (17). When a valve 55 of the heating body container A (51) is opened, air enters from an air intake port 56. Oxygen in air entered conducts oxidation reaction with a component of the heat generating body 5 to generate oxidation heat. The oxidation heat is transmitted to a hydrogen storage alloy 12 through the heat generating body container A (51) and the first tank 18 and the hydrogen storage alloy is heated. When the valve 55 is closed, entry of air is stopped, the reaction of the residual oxygen in the heat generating body container A (51) with the heat generating body 5 is finished, and heat generation is stopped. |
