Description of the Related Art A fuel cell using an oxide solid electrolyte such as zirconia has a high operating temperature of 800 to 1000 ° C., so that it has high power generation efficiency and does not require a catalyst, and the electrolyte is solid. It has features such as easy handling, and is expected as a third-generation fuel cell. However, the solid oxide fuel cell is difficult to realize because ceramics are the main structural material and are easily damaged by heat, and there is no suitable gas sealing method. For this reason, a cylindrical type fuel cell with a special shape has been devised, and the above two problems have been solved and the operation test of the cell has succeeded, but the power generation density per cell unit area is low and an economically advantageous one can be obtained. No prospect yet. In order to increase the power generation density, various flat plate types and their improved types have been studied.
