PURPOSE:To improve the durability by connecting airthight a plate-form beta-alumina to a storage container of cathode and anode active substances through a sealing material so as to form separate cells at both sides of the plate-form beta-alumina, an putting in the cathode and the anode active substances in the cells. CONSTITUTION:On both sides of a plate-form beta-alumina solid electrolyte 10, an anode metallic container 12 and a cathode metallic container 13 are connected airtight to form separate cells on both sides of the plate-form beta-alumina, and an anode active substance 14 and a cathode active substance 15 are stored in the cells respectively. As a result, the resistant force is large even to a stress at the connection generated depending on the ambient temperature variation in the operation time and in the stopped time of the cell, and there is no fear of generating breakage or damage at the connection. Consequently, a cell of large strength and excellent durability can be obtained. |
