Abstract

A solid electrolyte material contains an A site-deficient complex oxide represented by a chemical formula A BO , in which a B site contains at least Ga. This solid electrolyte material has stability, high oxide-ion conductivity at low temperature and high toughness. A method of manufacturing the solid electrolyte material, comprises: mixing oxide materials of respective constituent elements; baking temporarily the mixed materials at 1100 to 1200° C. for 2 to 10 hours; grinding the temporarily baked materials to powder; molding the powder; and sintering the molded powder. A solid oxide fuel cell, has: the solid electrolyte material; a cathode electrode formed on one surface of the solid electrolyte material; and an anode electrode formed on the other surface of the solid electrolyte material. The solid oxide fuel cell has a stable and long operation at low temperature.
