摘要： Problem: To provide a cell capable of suppressing cracking, a cell stack device, a module, and a module housing device. SOLUTION: The cell of the present invention comprises a first layer (7), in a region of a solid electrolyte layer (4) devoid of a second electrode layer (6). The first layer (7) contains an oxide as a primary component with a content of the rare earth element, the content different from a content of the rare earth element in the solid electrolyte layer (4). The oxide is same as an oxide contained as a primary component in the solid electrolyte layer (4). and the first layer (7) has a higher strength than the solid electrolyte layer (4). Furthermore, the cell stack device of the present invention comprises a plurality of these cells 100, 200, and 300, and is configured to electrically connect the plurality of cells. Furthermore, the module of the present invention is configured to house the cell stack device in a housing container. Additionally, the module housing device of the present invention is configured to house the above module and an auxiliary device for actuating the module in an exterior case.
