Abstract:
1. An electrolyte-electrode assembly comprising an electrolyte interposed between an anode and a cathode, wherein said electrolyte is composed of an apatite type oxide which contains a trivalent element and a tetravalent element, which has a composition formula represented by A wherein said electrolyte is a single crystal in which the crystal is oriented in said plane or said direction of said migration of said oxide ion, and said anode and said cathode are arranged perpendicular to a plane or a direction in which said oxide ion conduction of said electrolyte is high; and an isotropic conductive layer, in which said oxide ion conduction exhibits isotropy, is provided between said electrolyte and at least one of said anode and said cathode.
