<p>A polyelectrolyte fuel cell comprising a pair of electrodes each consisting of a hydrogen ionic-conduction polyelectrolyte film, a catalyst layer and a gas diffusion layer in contact with the catalyst layer, the both layers sandwiching the polyelectrolyte film, a conductive separator sheet having a gas flow path for supplying a fuel gas to one of the electrodes, and another conductive separator sheet having a gas flow path for supplying an oxidizing gas to the other of the electrodes, wherein, in order to keep a catalyst in a sufficient and uniform contact with the polyelectrolyte of the catalyst layer containing a hydrogen ionic-conduction polyelectrolyte and catalyst metal-supporting conductive carbon particles, the polyelectrolyte is disposed in pores in the agglomerate structure of the conductive carbon particles, thereby increasing a reaction area within the electrodes to deliver a higher performance.</p> |
