PROBLEM TO BE SOLVED: To provide a stack for a solid electrolyte fuel cell and a solid electrolyte fuel cell using this reducing film resistance by providing an electrolyte layer as a thin film, capable of sufficiently securing an electrode reaction area, and having high reliability to a used state with frequent starts and stops. SOLUTION: In the stack, cell plates with an air electrode layer and a fuel electrode layer held between solid electrolyte layers are laminated. A cell plate 6 has a substrate having a recessed groove in a top face or a bottom face, and each layer laminated on a substrate face of a recessed groove side in order of the fuel electrode layer, the electrolyte layer and the air electrode layer by transferring a shape of the recessed groove. Plural pairs of the cell plate are laminated so as to oppositely join fuel electrode layers or air electrode layers. A tubular groove formed by the junction functions as a gas passage for fuel or air. Cell plate sets 8 are laminated to form the stack 11. Consequently, gas sealability of a gas introducing part is improved, and since no separators are used, high temperature durability is improved. |
