Abstract

Provided is a solid electrolyte made of yttrium-doped barium zirconate having hydrogen ion conductivity, a doped amount of yttrium being 15 mol % to 20 mol %, and a rate of increase in lattice constant at 100° C. to 1000° C. with respect to temperature changes being substantially constant. Also provided is a method for manufacturing the solid electrolyte. This solid electrolyte can be formed as a thin film, and a solid electrolyte laminate can be obtained by laminating electrode layers on this solid electrolyte. This solid electrolyte can be applied to an intermediate temperature operating fuel cell.
