<P>PROBLEM TO BE SOLVED: To provide a fuel cell with gas pressure loss reduced and a drainage property improved. <P>SOLUTION: The fuel cell, made by laminating cells structured of a junction body 40 having an electrolyte film equipped with a fuel electrode and an air electrode, and a pair of separators 10 pinching the junction body 40, is provided with a porous flow channel layer arranged between either of the gas diffusion layers 42 each provided at the fuel electrode and the air electrode and the separators 10. The porous flow channel layer consists of a gas diffusion member 20 formed of a metal plate with a plurality of through-holes, and a part of the face of the gas diffusion layer 42 in contact with the gas diffusion member 20 is filled in a concave part 22 of the gas diffusion member 20 existing at an interface of the gas diffusion member 20 and the gas diffusion layer 42. <P>COPYRIGHT: (C)2009,JPO&INPIT |
