A solid polyelectrolyte fuel cell comprising catalyst layers disposed on the opposite faces of a solid polyelectrolyte consisting of ion exchange membranes, and collectors disposed on the outer sides of the layers, wherein the collectors are allowed to contain solvent-soluble fluorine-containing polymer (preferably, polymer having a fluorine-containing aliphatic ring structure) having substantially no ion exchange group, whereby the collectors can have a high water repellence for an extended period, and the fuel cell can operate with a high, stable output efficiency for an extended period. |
