PROBLEM TO BE SOLVED: To uniformize cell temperature through adjustment of calorific value by controlling a battery reaction quantity with adjustment of the thickness of an electrolyte having largest resistant in a cell constituting member. SOLUTION: In a solid electrolyte fuel cell composed of a solid electrolyte 2, a fuel electrode 3 and an oxidizing agent electrode 1, a thickness of the solid electrolyte 2 is made thicker it proceeds to inlets of respective passages from an outlet of a fuel gas passage and an outlet of an oxidizing agent gas passage made in the solid electrolyte fuel cell. A cell temperature at the time of power generation can be kept uniform, by making a thickness of the solid electrolyte large as a temperature becomes high, when a thickness of an electrolyte film is uniform, and a cell which hardly deteriorates with the lapse of time can be provided. |
