Process for producing solid oxide fuel cells

摘要

A process is disclosed for producing a solid oxide fuel cell including a solid electrolyte plate, and an air electrode and a fuel electrode provided on opposite surfaces of said solid electrolyte plate. The process comprising the step of joining a film of oxygen ion-conductive zirconia as the solid electrolyte plate to lanthanum manganate as the air electrode through a layer containing a compound selected from a manganese compound and a cobalt compound by press contacting them under heating.
