Abstract
A solid oxide fuel cell is disclosed, which includes flat plate-shaped solid oxide fuel cell elements. The solid oxide fuel cell element includes an ion-conductive ceramic plate, and an air electrode and a fuel electrode formed on opposite surfaces of the ion-conductive ceramic plate, respectively, wherein conductive strips which have less resistance than the electrode are continuously formed on a surface of at least one of the air electrode and the fuel electrode. A solid oxide fuel cell is also disclosed, which includes a separator plate made of a material having oxidation resistance, reduction resistance and electron conductivity, an air electrode spacer made of a material having oxidation resistance and electron conductivity, the above flat plate-shaped solid oxide fuel cell element, and a fuel electrode spacer made of a material having reduction resistance and electron conductivity, wherein the separator plate, the air electrode spacer, the flat plate-shaped solid oxide fuel cell element and the fuel electrode spacer are successively laminated in this order. An oxidizing gas chamber is defined by the separator plate, the air electrode spacer and the element, and a fuel gas chamber is defined by the separator plate, the fuel electrode spacer and the element. A process is also disclosed for producing such a solid oxide fuel cell element.
