PROBLEM TO BE SOLVED: To secure desired adhesive strength and resin strength with a compact configuration and furthermore to suppress generation of membrane deterioration at an electrode end as quickly as possible.SOLUTION: In a first resin-framed electrolyte membrane and electrode structure 10a, a plane dimension of an anode electrode 54 is set to a larger dimension than that of a cathode electrode 56. In an inside swollen part 58a of a first resin frame member 58, an adhesive coating part 62a is provided to which an outer peripheral edge 52e of a solid polymer electrolyte membrane 52 corresponding to the outer peripheral edge side of the anode electrode 54 integrally adheres. On the other hand, a thickness t2 of an anode diffusion layer 54b is set to a smaller dimension than a thickness t1 of a cathode diffusion layer 56b. |
