PROBLEM TO BE SOLVED: To prevent fracture of solid electrolytes caused by thermal stress, and to drive safely. SOLUTION: This fuel cell is constituted by alternately laminating cells where anodes 1 and cathodes 3 are formed on both sides of solid electrolytes 2, and separators 4A made of a NiCr heat resisting alloy. Oxidizing agent gas passage grooves 6A are formed by arranging and laminating gas passage groove forming members 7 having a thermal expansion coefficient smaller than that of the separators 4A and close to that of the solid electrolytes 2, and made of squared materials of LaMnO3 , between the cathodes 3 and the separators 4A. |
