Zusammenfassung:	PROBLEM TO BE SOLVED: To provide solid high polymer electrolyte fuel cell of stable cell operation, improved output performance, and low cost. SOLUTION: In a fuel cell comprising a cation exchange film as solid high polymer electrolyte, comprising a main chain formed of copolymer of a fluorine carbide vinyl monomer and hydrocarbon vinyl monomer and a hydrocarbon side chain including sulfonic acid groups, the cation exchange film comprises at least two layers of layered product having different water contents, and the water content of the cation exchange film facing a negative electrode is higher than the water content of that on the positive electrode side. The main chain is represented by formula I (where, in formula I, R is fluorine atom or fluoalkyl group of 1-3 carbon number; R is hydrogen atom or alkyl group of 1-3 carbon number; m is an integer of 1 or more; n is an integer of 1 or more), and the side chain is represented by formula II (where, in formula II, R , R , R are each hydrogen atom or alkyl group of 1-3 carbon number of; s is an integer of 1 or more; and t is an integer of 0 or 1 or more).
