<P>PROBLEM TO BE SOLVED: To stabilize power generation performance of a fuel cell by promoting wetness of its electrolyte film. <P>SOLUTION: The fuel cell 100 is equipped with: an electrolyte film 210; a first reaction gas flow channel 260 provided on a first face side of the electrolyte film; a second reaction gas flow channel 270 provided on a second face side of the electrolyte film; and a refrigerant flow channel 555. The flowing direction of the first reaction gas flowing in the first channel 260 is opposed to that of the second reaction gas flowing in the second channel 270, and the refrigerant channel 555 is constituted so that a downstream portion of at least either the first or the second reaction gas is cooled lower than a central portion on the inner face of the electrolyte film. <P>COPYRIGHT: (C)2010,JPO&INPIT |
