Abstract
There is a problem in that a gas pressure in an oxygen container of an oxygen supply device is high, thereby causing a mounting cost for charging gas into the oxygen container. Further, there is also a problem in terms of safety at a time of operation. A hydrogen occluding alloy container (5) containing a hydrogen occluding alloy which occludes the hydrogen is used as a hydrogen resource, an oxygen storage container (4b) containing an oxygen adsorbing material (23) that adsorbs the oxygen is used as an oxygen resource, a hydrogen heating means (11a) for heating the hydrogen occluding alloy container (5) and an oxygen heating means (11b) for heating the oxygen storage container (4b) are provided, and the hydrogen occluding alloy container (5) is heated by the hydrogen heating means (11a) and an excess exhaust heat obtained after the hydrogen occluded in the hydrogen occluding alloy is emitted is guided to the oxygen heating means (11b) to heat the oxygen storage container (4b), thereby promoting removal of the oxygen from the oxygen adsorbing material (23) and allowing a pressure of an oxygen gas to rise to supply the hydrogen and the oxygen to the fuel cell (1).
