<P>PROBLEM TO BE SOLVED: To provide a compact solid polymer fuel cell capable of largely being improved in its service life. <P>SOLUTION: This solid polymer fuel cell has a unit cell that comprises a polymer electrolytic film; a fuel pole and an oxidant pole placed to hold the polymer electrolytic film; a fuel pole side current collector having a fuel supply channel for supplying fuel gas to the fuel pole; and an oxidizing pole side current collector having an oxidant supply channel for supplying oxidant gas to the oxidant pole. Reinforcing sheets are held between the fuel pole and a polymer electrolytic film, and between the oxidant pole and the polymer electrolytic film. Edges of areas of the fuel electrode pole and oxidant pole contacting to the polymer electrolytic film sandwich the electrolytic film but do not overlap with each other. <P>COPYRIGHT: (C)2004,JPO |
