ず新たなガスシール構成の開発が必要である。Since the components of the battery are all solid, there is an advantage that the problem of the conventional battery, that is, the loss of electrolyte is completely eliminated, and that the operating temperature is as high as 1000 ° C., so that the power generation efficiency is high. However, it is also true that there are many problems such as selection of a constituent material that is stable for a long time at a high temperature, a method of attaching an electrode to a solid electrolyte, and a gas sealing method. In particular, in the sealing method between the flat cell and the gas separation plate, it is not possible to take the form of a wet seal like a conventional battery, and it is necessary to develop a new gas seal configuration.

出によりやがて短絡を起すという問題があった。The applicant has already applied, as a sealing method between the flat cell and the gas separation plate, to a storage portion formed integrally with each gas separation plate, or a storage portion formed by a bottomed box that stores the entire stack. A configuration is proposed in which sealing is performed on the outer peripheral side of each cell or the outer peripheral side of the stack by filling a non-conductive high-viscosity melt. (Japanese Patent Application No. 1-367711) However, since molten glass is used as a non-conductive high-viscosity melt, the heat resistance that comes into contact with the molten glass during long-term use due to alkali ions such as sodium and potassium usually contained in the glass. There is a problem that the metal corrodes and the metal ions eluted in the glass precipitate and eventually cause a short circuit.
