A cell stack device according to the present disclosure includes: a cell stack comprising a plurality of cells; and a manifold configured to supply reaction gas to the plurality of cells, wherein each of the plurality of cells includes: an element part comprising: a fuel electrode layer that is located on the fuel electrode layer; a solid electrolyte layer that is located on the fuel electrode layer; a middle layer that is located on the solid electrolyte layer; and an air electrode layer that is located on the middle layer, the middle layer including: a first middle layer bonded to the solid electrolyte layer; and a second middle layer bonded to the air electrode layer; and a non-element part of the cell that comprises the entire cell excluding the air electrode layer, the non-element part located at least at a first of both ends of the plurality of cells in a longitudinal direction, and the plurality of cells is fixed to the manifold at least at the first end by a sealing material located between the manifold and either the solid electrolyte layer or the first middle layer.

Cell stack device, module, and module housing device

A cell stack device including: a cell stack comprising a plurality of cells; a support member; and a fixing part between the support member and the at least one cell of the plurality of cells, wherein in a cross section including the support member, the fixing part, and the at least one cell, the fixing part includes: a first region arranged close to the support member; a second region closer to the at least one cell than the first region; and a third region between the first region and the second region, and at least one of the first region and the second region includes a porous region having a porosity that is higher than a porosity of the third region.

A cell stack device includes a cell stack including a plurality of cells arranged, and a manifold configured to allow a reaction gas to be supplied to the plurality of cells. First end portions of the plurality of cells are fixed to the manifold with a sealing material. The plurality of cells each include: a supporting substrate extending in a length direction; an element portion including a fuel electrode, a solid electrolyte layer, and an air electrode layered on the supporting substrate; and an interlayer located between the solid electrolyte layer and the air electrode, extending to each of the first end portions of the plurality of cells, and having a porosity greater than a porosity of the solid electrolyte layer. The interlayer includes an exposed portion exposed from the air electrode at each of the first end portions of the plurality of cells and the sealing material provided on the exposed portion.
