PURPOSE: To provide a polymer solid electrolyte fuel cell of which ion conductivity is improved by lowering the specific resistance of an ion exchange membrane and in which water control can be carried out so as to allow of no- humidification operation. CONSTITUTION: In a solid electrolyte fuel cell comprising a collector 1 for a cathode, a catalytic layer 2 for the cathode, an ion exchange membrane 3, a catalytic layer 4 for an anode, and a collector 5 for the anode which are united, finely granulated silica and/or fibrous silica fiber is added to the catalytic layer 1 for the cathode and the catalytic layer 4 for the anode. Consequently, the specific resistance of the fuel cell is lowered and the ion conductivity is improved and at the same time no-humidification operation can be carried out. |
