<P>PROBLEM TO BE SOLVED: To provide a polymer electrolyte fuel cell with a seal structure so made to secure enough gas tightness while preventing entry of impurities from cooling water into electrodes and an electrolyte film. <P>SOLUTION: The polymer electrolyte fuel cell, provided with cells structured to pinch a solid polymer electrolyte film and electrodes between a pair of separators having a cooling water manifold circulating cooling water and a gas manifold circulating gas, further includes a gas seal going around a gas flow channel face and a cooling water seal going around a periphery of the cooling water manifold. Moreover, the cooling water seal is fitted further outside than an outer edge of the solid polymer electrolyte film, so that the electrolyte film is not to be in direct contact with the cooling water. <P>COPYRIGHT: (C)2009,JPO&INPIT |
