PURPOSE:To simplify the construction of a fuel cell and reduce the internal resistance thereof by forming the films of a fuel electrode, a solid electrolyte and an air electrode in sequence on one side of a dense substrate comprising the same material as a fuel electrode part and having many through-holes. CONSTITUTION:In a solid electrolyte type fuel cell comprising a solid electrolyte 1, an air electrode 2 and a fuel electrode 3, one side of a dense substrate comprising the same material as the fuel electrode 3 and having many through-holes is applied with the films of the fuel electrode 3, the solid electrolyte 1 and the air electrode 2 respectively in that order. As the substrate is manufactured according to the aforesaid process, the high strength and small thickness thereof can be ensured. Also, even for a large fuel cell, compact construction can be applied. In addition, the internal resistance of the fuel cell can be lowered and the conductivity thereof can be increased, thereby improving cell performance. |
