<P>PROBLEM TO BE SOLVED: To provide a fuel cell which has a sealing structure of each unit cell and can be made light and thin and can obtain an ample power output, by enhancing the contact pressure of an electrode plate. <P>SOLUTION: The fuel cell has a solid polymer electrolyte plate 1, a cathode electrode plate 2 fixed on one side of the electrolyte plate 1, an anode electrode plate 3 fixed on the other side of the electrolyte plate 1, a cathode metal plate 4 fixed on the surface of the cathode electrode plate 2 and making gas to flow to the inner surface side, and an anode metal plate 5 fixed on the surface of the anode electrode plate 3 and making fuel flow inside. The circumference of both plates 4, 5 are in the electrically insulated and sealed state, passage grooves are formed at least on the inside of the anode metal plate 5 and a convex and curved contact part 5r is formed between the passage grooves 9 that is formed in parallel. <P>COPYRIGHT: (C)2007,JPO&INPIT |
