Abstract
A first method for manufacturing a solid oxide film having a highly densified solid oxide film having a small thickness and an improved electric conductivity; and a second method for manufacturing a solid oxide fuel cell in which a solid oxide film formed on an air electrode or a fuel electrode is manufactured by the first method. The solid oxide fuel cell according to the present invention is capable of generating a high power. The solid oxide film is formed on a substrate in such manner that a solid oxide material is sprayed on the substrate to form a sprayed solid oxide film thereon; Then a solution of metal compound including at least one metal selected from a group of manganese, iron, cobalt, nickel, copper and zinc is impregnated into the sprayed solid oxide film; and the sprayed solid oxide film is subjected to a heat treatment in order to increase an airtightness of the film. It may be possible to use a material for spraying, in which 1.about.10 parts by weight of an oxide of said metal is contained, instead of the impregnation, or to obtain a material for spraying by mixing the compound powder containing the metal and the solid oxide material in a spray gun via separately arranged powder supply devices.
