Abstract

An SOFC is provided with an oxidizing electrode layer, a reducing electrode layer opposite to the oxidizing electrode layer, a solid electrolyte layer between the oxidizing electrode layer and the reducing electrode layer, and an alternating laminated structural section between the oxidizing electrode layer and the solid electrolyte layer or between the reducing electrode layer and the solid electrolyte layer. The alternating laminated structural section has a first thin film layer including a material of corresponding one of the electrode layers and a second thin film layer having a phase including the material of the corresponding one of the electrode layers and that of the solid electrolyte layer. The first thin film layer and the second thin film layer are alternately laminated.
