PROBLEM TO BE SOLVED: To provide a single cell for direct flame fuel cell in which such a problem that the output cannot be obtained because the temperature on the air electrode layer side does not rise during power generation, and the ionic conductivity is reduced can be solved.SOLUTION: A single cell 10 is obtained by laminating a fuel electrode layer (A)21, a zirconia based solid electrolyte layer (b-1)31, a ceria-based solid electrolyte layer (b-2)32, and an air electrode layer (C)41 sequentially. A solid electrolyte layer (B) includes the zirconia based solid electrolyte layer (b-1), and the ceria-based solid electrolyte layer (b-2) laminated sequentially from the fuel electrode side. Furthermore, high output can be obtained when the fuel electrode layer (A) has a two layer structure of a first fuel electrode layer (a-1) and a second fuel electrode layer (a-2). |
