<P>PROBLEM TO BE SOLVED: To provide a solid polymer fuel cell hardly causing breakage of film even when a large dimensional change on the electrolyte film occurs in the face direction by swelling, stretching, or shrinkage due to wetting or drying. <P>SOLUTION: This solid polymer fuel cell is provided with the electrolyte films in which outer edge side faces are sealed by sealers 90 via dry and wet swelling and telescopic motion materials 40. At further outside the dry and wet swelling telescopic motion materials in which the electrolyte films are pinched, materials more rigid than the dry and wet swelling and telescopic motion materials are arranged, and the dry and wet swelling and telescopic motion materials are pinched by these rigid materials. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
