<P>PROBLEM TO BE SOLVED: To keep good power generation reaction by surely preventing dwelling of generated water on the outlet side of a reactive gas flow path. <P>SOLUTION: A fuel cell 10 includes a cathode side separator 14. On a surface 14a of the cathode side separator 14, an oxidant gas flow path 24 is provided. The oxidant gas flow path 24 includes a plurality of inlet side flow paths 24a communicating with an oxidant gas inlet communication hole 18a, a plurality of outlet side flow paths 24b communicating with an oxidant gas outlet communication hole 18b, and a plurality of intermediate flow paths 24c whose both ends communicate with the inlet side floe path 24a and the outlet side flow path 24b. The flow path length of the outlet side flow path 24b is set longer than that of the inlet side flow path 24a, and the outlet side flow path 24b becomes narrower in flow path width as advances toward the oxidant gas outlet communication hole 18b. <P>COPYRIGHT: (C)2010,JPO&INPIT |
