FUEL CELL
DRIVE
April 2, 2003
In order to provide a fuel cell with high discharge property by a production step that involves reduced variation in the coating amount with little occurrence of coating failure, a fuel cell is provided, which comprises: a hydrogen ion-conductive polymer electrolyte membrane; a pair of electrodes, each formed by laminating a catalyst layer in contact with the polymer electrolyte membrane and a gas diffusion layer in contact with the catalyst layer; and a pair of conductive separators, one of which having a gas flow path for supplying and discharging an oxidant gas to and from one of the electrodes and the other having a gas flow path for supplying and discharging a fuel gas to and from the other of the electrodes, wherein the gas diffusion layer in at least one of the electrodes contains a nonfibrous water-repellent polymer.
