PURPOSE:To prevent generation of crack at the time of elevating temperature by forming supporting frames made of the same material as that of a solid electrolyte layer in the circumference of a generating film, and locating packing materials between the supporting frames and interconnectors. CONSTITUTION:A supporting frame 7 made of the same material as that of the solid electrolyte as main material of a generating film 5 is adhered to the circumference of the generating film 5 to improve the strength. Furthermore, a heat resistant packing material 8 is located between the generating film 5 and an interconnector 9 respectively having a coefficient of thermal expansion different from each other. Consequently, gas seal is performed without adhering strongly to reduce a difference of coefficients of thermal expansion thereof. Generation of crack to be caused by a difference of coefficients of thermal expansion between the materials at the time of elevating temperature of a battery main member can thereby be prevented to obtain the high generating property and durability. |
