摘要： When a polymeric electrolyte type fuel cell operating at about 60.degree. C. is used, heating with exhaust gas becomes difficult. Therefore, a polymeric electrolyte type fuel cell (PEM) is adopted as a fuel cell body, and a hydrogen storage vessel made of a metal containing hydrogen is connected to the PEM by a hydrogen supply piping via a humidifier for humidifying the electrolyte membrane of the PEM. The PEM and the hydrogen storage vessel are connected by a copper plate which is a conductor of heat. Heat generated in the PEM is transferred to the hydrogen storage vessel by this copper plate, and elevates the temperature and pressure in the vessel. By this, hydrogen is well supplied to the PEM.
