PROBLEM TO BE SOLVED: To provide an electrolyte film and electrode junction for a fuel cell with excellent proton conductivity, a polymer electrolyte fuel cell of high efficiency using the same, and a method of manufacturing the above electrolyte film and electrode junction with ease and in stable quality. SOLUTION: A polymer electrolyte film including carbon particles supporting metal contained on both sides of a surface layer, an electrolyte film and electrode junction equipped with a pair of gas-diffusion layers arranged on its both sides, and a fuel call using the same are provided. The electrolyte film is formed by applying dispersion liquid of polymer electrolyte with at least two kinds of metal-supporting carbon particles of hydrophilicity or with different specific weights dispersed on a support, having the particles in the dispersion liquid applied above precipitated and floated according to their hydrophilicity or specific weights, and then, by volatilizing solvent in the dispersion liquid in that state. |
