PROBLEM TO BE SOLVED: To provide an inorganic electrolyte film, by which a fuel cell that has a high battery performance even if it is used under high temperature for a long period of time, can be obtained. SOLUTION: It is an inorganic electrolyte film, which consists of inorganic proton-conductive oxide particles and inorganic matrix ingredients. The above inorganic proton-conductive oxide particle consists of a hydrated oxide antimony particle expressed with the formula Sb2 O5 .nH2 O (n=0.1 to 5), an average particle diameter of this particle is in the range of 5 to 50 nm, and the quantity of content of the hydrated oxide antimony particle is in the range of 5 to 80 weight % by converting it with an oxide (Sb2 O5 ). |
