<P>PROBLEM TO BE SOLVED: To provide a gas passage forming member used for a power generation cell capable of suppressing biting of the contact part of a gas passage forming member into a gas diffusion layer and enhancing the power generation efficiency of a fuel cell by optimizing the contact state of the gas passage forming member and a separator. <P>SOLUTION: An MEA 15 is housed in the inside of framework-like frames 13, 14, and first and second gas passage forming members 21, 22 are interposed between an anode layer 17 and a cathode layer 18 of the MEA 15 and first and second separators 23, 24 joined to the upper and lower surfaces of the frames 13, 14. The gas passage forming member 22 is formed with a lath cut metal 25, and the forming width of a first plane part 29a coming in contact with the surfaces of gas diffusion layers 19, 20 out of a ring part 27 forming a through hole of the gas passage forming member 22 is set wider than the forming width of a second plane part 30a coming in contact with the separator 24. <P>COPYRIGHT: (C)2010,JPO&INPIT |
