ABSTRACT:
A fuel cell proper is constructed by superposing a plurality of unit cells having a solid polymer electrolyte membrane held between an anode and a cathode. This fuel cell proper is cooled with a liquid having a boiling point closely approximating the working temperature of the fuel cell. Water and a liquid fuel as liquid raw materials are gasified with a liquid raw material gasifying mechanism. This liquid raw material gasifying mechanism uses, as at least part of the heat source for gasification of water, the waste heat from the reformer and the heat possessed by the reformed gas. The gasified water and liquid fuel are reformed by the reformer into a hydrogen rich gas. The gas thus produced is supplied to the anode in the fuel cell proper. The cathodes are supplied with air to effect a reaction for power generation.
