<P>PROBLEM TO BE SOLVED: To suppress deterioration in the power generation efficiency of a fuel cell. <P>SOLUTION: The fuel cell 10 includes a membrane electrode assembly 100 and reaction gas passages 200, 250 arranged on both faces of the membrane electrode assembly. The reaction gas passages 200, 250 are respectively configured, such that a cross-sectional area vertical to a flow direction of reaction gas is gradually reduced from the upstream side toward the downstream side of the reaction gas passage, and the reaction gas passage includes a partition wall 300, separating the reaction gas passage in a thickness direction of the reaction gas passage, on the upstream side of the gas passage. <P>COPYRIGHT: (C)2011,JPO&INPIT |
