[Problem] To provide a cell, a cell stack device, a module, and a module storage device that enable reduction in the possibility of occurrence of damage. [Solution] The present invention comprises: a support body 1 which has a column shape, contains nickel, has gas passages 2 penetrating the inside of the support body 1 along the longitudinal direction, and has one end portion at which the outlets of the gas passages 2 are provided and the other end portion at which the inlets of the gas passages 2 are provided; a first electrode layer 3 positioned on the support body 1; a solid electrolyte layer 4 positioned on the first electrode layer 3; and a second electrode layer 6 positioned on the solid electrolyte layer 4, wherein in the support body 1, the metal nickel content in the one end portion is less than that in the center portion in the longitudinal direction. Thus, a cell 10 that enables suppression of occurrence of damage is obtained. |
