Abstract
Provided is a solid electrolyte material which, while maintaining high oxygen ion conductivity, minimizes the decomposition of scandia caused by impurities such as silicon in the fuel gas, and improves intergranular strength in order to eliminate intergranular fracture caused by crystalline modification. The solid electrolyte material is a zirconia solid electrolyte material having scandia and a lanthanoid oxide and/or yttria dissolved therein, and has alumina further added thereto.
