<P>PROBLEM TO BE SOLVED: To provide a fuel cell prevented from damage to a membrane due to bending of the membrane between an end of a diffusion layer and an inner surface of an electrolyte membrane holder of a separator. <P>SOLUTION: (1) A fuel cell of which distance between a pair of diffusion layer contacts 40 is larger than that between a pair of electrolyte membrane holders 41 is filled in a space between an end in plane direction 43 of the diffusion layers 13 and 16 and the electrolyte membrane holder 41 with an adhesive 44. (2) The shape of the inner end of the electrolyte membrane holder 41 is made so that the distance C between the end in plane direction 43 of the diffusion layer and the electrolyte membrane holder 41 at the straight part and the corner may be approximately same. (3) The fuel cell is provided with the structure satisfying the above (1) and (2). (4) The shape of the inner end 42 of the electrolyte membrane holder 41 at the part opposing to the corner of the diffusion layer is chosen from either of a bent shape or a chamfered shape. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
