摘要 |
A polymer electrolyte fuel cell comprising an anode, a cathode, a polymer electrolyte membrane interposed between the anode and the cathode, an anode-side separator plate having a gas flow path to supply fuel gas to the anode and a cathode-side separator plate having a gas flow path to supply oxidant gas to the cathode. Each of the anode and the cathode comprises a catalyst layer in contact with the polymer electrolyte membrane, an electrode supporting material having gas permeability and electronic conductivity, and a water repellent layer interposed between the catalyst layer and the electrode supporting material. The water repellent layer has through holes through which the catalyst layer and the electrode supporting material are electrically connected. <IMAGE> |
