PURPOSE:To provide a solid polymer electrolytic fuel cell for which a humidification part, which is easily assembled and has good humidification ability, and which also contributes to cooling of the fuel cell, is integrated therein. CONSTITUTION:A plurality of solid polymeric films 22 having ion conductivity, and a plurality of single cells consisting of a fuel electrode 3 and an oxidant electrode 4 that are adhered to the both surfaces of the film 22, are formed through bipolar plates 25A, 25B having a fuel gas channel 6 consisting of recessed groove and an oxidant channel 7, in the part opposed to the fuel electrode and to the oxidant electrode on the both surfaces of a gas non-permeation plate. The solid polymeric film 22 is extended to a fixed length in the both directions of the fuel electrode 3 and the oxidant electrode 4 which are opposed to one another, and a humidification part 36 of fuel gas is provided on the side of one extended part 22B while a humidification part 37 of oxidant is provided on the side of the other extended part 22A, with the extended parts serving as water permeation films. |
