<P>PROBLEM TO BE SOLVED: To provide a fuel cell with further improved cooling efficiency, capable of easily and surely controlling flow amount of cooling media in a separator face. <P>SOLUTION: A plurality of first convex parts 44 are formed on a backside of a fuel gas flow passage 42 by arranging the fuel gas flow passage 42 on a first separator 24, and second convex parts 48 are formed on a backside of an oxidant gas flow passage 46 by arranging the oxidant gas flow passage 46 on a second separator 26. First top faces 44a of the first convex parts 44 and second top faces 48a of the second convex parts 48 constitute a continuous contact part 52 for forming separation parts 50 forming cooling media flow passages 54, and sealing areas preventing the cooling media from flowing. <P>COPYRIGHT: (C)2007,JPO&INPIT |
