ABSTRACT:
A solid oxide fuel cell which has high output capacity especially at an operating temperature of 600° C.-800° C. and effectively prevents influence of reaction between respective layers. The solid oxide fuel cell includes a solid electrolyte layer between a fuel electrode and an air electrode, a support comprised of either the fuel electrode or the air electrode, and at least first and second layers provided in turn from the side of the support. The first layer is comprised of a cerium-containing oxide and the second layer is comprised of a lanthanum-gallate oxide containing at least lanthanum and gallate. A sintering assistant for improving sintering property of the cerium-containing oxide is contained in the first layer. When the thickness of the second layer is T μm, the value of T is 2<T<70.
