では、モジュールを小型化するのに限界があった。In the solid electrolyte fuel cell as described above, miniaturization of the module is mentioned as one of the items required for practical use. In such a cell as described above, since a single element is formed on the base tube, the operating area depends on the length of the single element and the diameter of the base tube. Therefore, in order to reduce the size of the module, it is important to improve the output per unit area and reduce the number of cells used.
In other words, when using cells having limited dimensions, it is necessary to improve the output per unit area by improving the output of the single cell itself. However, in the current cell constituent material, 0.3 to 0.5 A / cm
Since about 2 is considered to be the limit, there is a limit in miniaturizing the module only by improving the single cell performance.
