<P>PROBLEM TO BE SOLVED: To suppress compression deformation of a gas flow passage when a pressing force is applied from both faces of a separator in a fuel cell. <P>SOLUTION: A single cell 100 is constituted by laminating an anode side gas flow passage forming member 20 and an anode side elastic member 40 on an anode side surface of a membrane electrode assembly 10 in this order, by laminating a cathode side gas flow passage forming member 30 and a cathode side elastic member 50 on a cathode side surface of the membrane electrode assembly 10 in this order, and by pinching these both faces by a separator 60 and the separator 70. Then, elastic modulus possessed by the anode side elastic member 40 and the cathode side elastic member 50 is provided by members which have higher elastic modulus than that of the anode side gas flow passage forming member 20 and the cathode side gas flow passage forming member 30. <P>COPYRIGHT: (C)2008,JPO&INPIT |
