Summary: | PROBLEM TO BE SOLVED: To provide an electrode structure for solid polymer furl cell having a cheap polymer electrolyte film made of ion conductive material, with excellent power generating property. SOLUTION: For the electrode structure for solid polymer furl cell, a polymer electrolyte film has repeating units expressed by the formula 1 or the formula 2, and composed of a sulfonated compound of polyether group of which, the range of molecular weight is 10,000-1,000,000. An electrode catalyst layer contains platinum within a range of 0.01-0.6 mg/cm , and the range of average diameter of carbon grain is 10-100 nm. In the formulae, X represents an electron attractive radical, R1 and R2 represent H or hydrocarbon radical with one valence, R3 -R6 represent H, halogen atom, or cyanic radical, a and b represent integers of 0-4, C is 0 or 1, d is 1 or 2. As for Y, 2,5-dihydroxybiphenyl, 4,4'- dichlorobenzophenone, 4,4'-(9H-fluorene-9-ylidene)bisphenol and the like are shown as examples. |
