<P>PROBLEM TO BE SOLVED: To provide a fuel cell capable of aiming at uniformalization of temperature distribution doing without flow unevenness of a cooling medium flowing in an active area. <P>SOLUTION: In the fuel cell pinching a membrane electrode assembly 14 with separators 15 forming fuel gas flow channels 17, oxidant gas flow channels 18 and coolant flow channels 19 by sticking together metal plates 15A, 15B taking on a concavo-convex shape alternately forming concave parts 26 and convex parts 27 in an area contributing to power generation, a part not contributing to power generation out of the plurality of coolant flow channels 19 is blocked by crushing the convex parts 27 as a part of the flow channel where the coolants flow, and an adhesive is coated and filled in those crushed recessed parts 28. <P>COPYRIGHT: (C)2009,JPO&INPIT |
