ABSTRACT:
This invention provides a solid electrolyte fuel cell operable with high efficiency even in the temperature range of about 850.degree. to 650.degree. C., The invention is characterized by the use of a novel perovskite double oxide of the composition A.sub.X B.sub.Y O.sub.3-.alpha.. The fabrication of the electrolyte, air electrode and fuel electrode layers by tape casting has contributed to marked improvement in processability and productivity.
