    Abstract: An intermediate layer containing CeO2 with which a rare earth element (excluding Ce) forms a solid solution and a first electrode layer may be disposed in this order on a surface on one side of a solid electrolyte layer containing Zr, and a second electrode layer may be disposed on a surface on another side opposite the surface of the one side of the solid electrolyte layer. The intermediate layer includes a first layer located closer to the solid electrolyte layer and a second layer disposed on the first layer and located closer to the first electrode layer, and a concentration of the rare earth element of the first layer may be greater than a concentration of the rare earth element of the second layer.

    Abstract: A solid oxide fuel cell having an electric power generating element unit that is configured by sandwiching a solid electrolyte layer between a fuel electrode layer and an oxygen electrode layer with a pore that is present in the solid electrolyte layer and is covered with a sealing material. In addition, a pore that is present in an interconnector, which is electrically connected to the fuel electrode layer or the oxygen electrode layer, is covered with the sealing material. Consequently, the solid oxide fuel cell is capable of easily preventing gas leakage.

    Abstract translation: 一种具有发电元件单元的固体氧化物型燃料电池，其特征在于，在所述固体电解质层中存在固体电解质层并且被密封材料覆盖的情况下，将固体电解质层夹在燃料电极层和氧电极层之间。 此外，存在于与燃料电极层或氧电极层电连接的互连器中的孔被密封材料覆盖。 因此，固体氧化物型燃料电池能够容易地防止气体泄漏。

    Abstract: 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.
