Abstract
A solid oxide fuel cell including at least one kind of an electrically conductive film formed by spraying and having a permeability constant of nitrogen gas being not more than 9.times.10.sup.-8 cm.sup.4 /g.sec. A process for producing a solid oxide fuel cell, including the steps of: forming a sprayed film on a substrate by spraying a material for the formation of an electrically conductive film, while a thickness of a sprayed film per one pass of a spraying gun is being suppressed to not more than 10 .mu.m, and then forming the electrically conductive film by thermally treating the sprayed film.
