PURPOSE:To facilitate the control of humidification by a simple generating system, and improve generating efficiency by using a solid polymer electrolytic film constituted to contain water so that protons are diffused in the film. CONSTITUTION:Hydrogen is supplied to the anode 2 of a fuel cell 1 by a piping 5, and air is supplied to a cathode 3 by a piping 6. Further, cooling water is supplied to a cooling plate 4 by a piping 7. A cell is formed of a solid polymer electrolytic film 18 and a separator nipping the film 18 to supply a humidified and heated reaction gas to the electrodes. Since the film 18 contains water so that proton is diffused in the film, the moisture required for the operation of the fuel cell can be controlled by the water quantity added to the reaction gas. Since reaction heat energy of the fuel cell can be utilized for the evaporation of the humidifying moisture, generating efficiency can be enhanced more than in a conventional cell, and the facility can be simplified as the whole. |
