PURPOSE:To make it possible to quickly remove water generated in a fuel electrode by forming a nickel film on the inner surface of a substrate pipe in a solid electrolyte fuel cell. CONSTITUTION:A 10-30mum thick porous nickel film 12 is formed by vapor deposition on the inner surface of a substrate pipe 11. A thin fuel electrode 13 is formed by thermal spray on the substrate pipe 11, and an alumina layer 14 is also formed. An electrolyte 15 is formed so as to extend onto the alumina 14 on the fuel electrode 13, and an interconnector 16 is formed on the alumina 14 and the fuel electrode 13. An air electrode 17 is formed on the electrolyte 15, the alumina 14, and the connector 16. By forming the nickel film 12 on the inner surface of the substrate pipe 11, water generated in the fuel electrode 13 during power generation can smoothly be removed. |
