摘要： A small-size and light-weight electrochemical module in which, when a stack expands the stack can be clamped appropriately. The electrochemical module includes: an electrochemical element stack obtained by stacking, in a predetermined stacking direction, a plurality of electrochemical elements having a configuration in which an electrolyte layer, and a first electrode and a second electrode that are respectively arranged on two sides of the electrolyte layer, are formed along a substrate; an elastic plate-like member arranged along at least one of a first flat face and a second flat face of the electrochemical element stack; and a clamp that includes a first clamping portion extending along the first flat face and a second clamping portion extending along the second flat face and clamps the electrochemical element stack via the plate-like member.

摘要： A fuel cell module has a fuel cell stack and an oxidant gas supply plate. The fuel cell stack is arranged inside a housing. The oxidant gas supply plate is arranged adjacent to the fuel cell stack within the housing. The oxidant gas supply plate has an inner space. The oxidant gas supply plate is positioned separated away from an inner wall of the housing on the first direction side so that a space on the fuel cell stack side communicates with a space on the side opposite to the fuel cell stack side. The oxidant gas supply plate has a surface facing the fuel cell stack and a surface on the opposite side of the fuel cell stack, both being connected directly or indirectly to the housing.

摘要： The fuel cell system includes a fuel cell stack and a predetermined device. A gas receiving portion for receiving an exhaust gas from the fuel cell stack is formed in the predetermined device. The gas outlets of the fuel cell stack and the gas receiving portion are connected via a pipe. An upstream portion of a joint tube made of an insulator is inserted into a downstream opening of the pipe. The joint tube has a hollow protrusion with a smaller outer diameter than the upstream portion. The hollow protrusion protrudes upstream (inside the pipe) from the upstream portion in the flow direction of the exhaust gas.

摘要： A cell according to the present disclosure includes: a first electrode layer; a solid electrolyte layer on the first electrode layer, the solid electrolyte layer containing Zr; a middle layer on the solid electrolyte layer, the middle layer containing CeO2 which contains Ce and a rare earth element other than Ce; a second electrode layer on the middle layer; and a boundary region between the solid electrolyte layer and the middle layer, the boundary region including a basing point at which a molarity of Ce and a molarity of Zr are equal. An average molarity of the Ce within a range from the basing point up to 3 μm toward the solid electrolyte layer is equal to or less than 10 mol % with respect to a total of Ce, Zr, and other rare earth elements, an average molarity of Zr within the range is equal to or more than 70 mol % with respect to a total of Ce, Zr, and other rare earth elements, or a molarity ratio of Ce with respect to Zr within the range is equal to or less than 0.143.
