<P>PROBLEM TO BE SOLVED: To prevent mechanical damage to a membrane-electrode assembly in a fuel cell having a structure in which a porous body as a reaction-gas flow path is interposed between the membrane-electrode assembly and a separator. <P>SOLUTION: A fuel cell 100 includes a fuel-gas flow-path constituting member 20a and an oxidant-gas flow-path constituting member 20c respectively between an anode of a membrane-electrode assembly 10 and a separator 30a and between a cathode of the membrane-electrode assembly 10 and a separator 30c. The fuel-gas flow-path constituting member 20a includes an anode contact part in contact with the anode on the surface of the side facing the anode while the oxidant-gas flow-path constituting member includes a cathode contact part in contact with the cathode on the surface of the side facing the cathode. In the fuel-gas flow-path constituting member 20a and the oxidant-gas flow-path constituting member 20c, the anode contact part and the cathode contact part are respectively arranged at a position where part of the anode contact part and part of the cathode contact part face each other across the membrane-electrode assembly 10. <P>COPYRIGHT: (C)2009,JPO&INPIT |
