A solid electrolyte type fuel cell having decreased internal resistance and increased output and improved fuel utilization efficiency is provided. The fuel cell includes an air electrode substrate made of a perovskite series complexed oxide having the following composition of a formula (La1-yAy)MO3, wherein A is at least one element selected from alkaline earth metals, M is manganese or cobalt, and y is 0</=y</=0.4, a zirconia solid electrolyte film containing manganese or cobalt solid soluted at at least the neighborhood of the interface thereof with the air electrode substrate, and a fuel electrode film formed on the solid electrolyte film at a surface opposite to the air electrode substrate. The fuel cell does not include a highly resistive layer made of a compound containing lanthanum and zirconium at the interface between the air electrode substrate and the solid electrolyte film. Methods for producing the fuel cell are also disclosed. |
