Abstract
A cell unit CU includes a cell structure, a metal support platedisposed on one side surface of the cell structure, and a frameholding an outer peripheral part of the support plate. The cell structurehas a lamination of an anode electrode layer, an electrolyte layer, and a cathode electrode layer, in this order. The frameincludes a displacement guideat least on one side surface of the frame. The displacement guidehas a coefficient of thermal expansion that is different from that of the frameand is configured to make the framecurve so that the cell structureis concaved in accompany with thermal expansion. In the cell unit CU, a risk of concentration of tensile stress on the electrolyte layerat the time of thermal expansion during operation is removed without reducing the strength of the frame, whereby occurrence of a crack and the like in the electrolyte layercan be prevented beforehand.
