GAS FLOW PASSAGE FORMING MEMBER, METHOD OF MANUFACTURING THE GAS FLOW PASSAGE FORMING MEMBER, AND DEVICE FOR FORMING THE GAS FLOW PASSAGE FORMING MEMBER |
摘要 |
An MEA 15 is arranged between frames 13, 14. A first gas flow passage forming member 21 is arranged between an anode electrode layer 17 of the MEA 15 and a first separator 23 fixed to an upper surface of the frame 13. A second gas flow passage forming member 22 is arranged between a cathode electrode layer 18 of the MEA 15 and a second separator 24 fixed to a lower surface of the frame 14. The gas flow passage forming members 21, 22 are each formed by a metal lath 25. The metal lath is formed by forming a plurality of through holes 26 in a thin metal plate in a mesh-like manner and forming the thin metal plate in a stepped shape. The gas flow passage forming members 21, 22 each include a plurality of annular portions 27 forming the through holes 26. Each of the annular portions 27 has a flat surface portion 28a in a first contact portion 28, which contacts a carbon paper 19, 20.
