Abstract: An electric power generation cell 1 is constituted by arranging a fuel electrode layer 4 on one side of a solid electrolyte layer 3 and an air electrode layer 2 on the other side of the solid electrolyte layer 3. The solid electrolyte layer 3 is constituted of an oxide ion conductor mainly composed of a lanthanum gallate based oxide. The fuel electrode layer 4 is constituted of a porous sintered compact having a highly dispersed network structure in which a skeletal structure formed of a consecutive array of metal grains is surrounded by mixed conductive oxide grains. For the air electrode layer 2, a porous sintered compact mainly composed of cobaltite is used. This configuration reduces the overpotentials of the respective electrodes and the IR loss of the solid electrolyte layer 3, and accordingly can actualize a solid oxide type fuel cell excellent in electric power generation efficiency.

Abstract: Provided is a power generation cell for a solid electrolyte fuel cell, in which a lanthanum gallate-based electrolyte is used as a solid electrolyte. Use of alternative energy for replacing petroleum can be promoted and it is possible to use waste heat using the solid electrolyte fuel cell, thus the solid electrolyte fuel cell is watched in views of resource nursing and the environment. The power generation cell is typically operated at 800 to 1000° C. However, currently, the power generation cell, which is operated at 600 to 800° C. by using the lanthanum gallate-based electrolyte, is suggested. Since a current power generation cell has a large size and has an insufficient output, there are demands for size reduction and high output. In the power generation cell, Sm-doped ceria particles are separately attached to a surface of porous nickel having a network frame structure. The demands are satisfied by using the anode.

To achieve the object, in the present invention, a fuel-electrode layer 3 and an air-electrode layer 4 are disposed on both surfaces of a solid electrolyte layer 2; a fuel-electrode-side porous metal 6 and an air-electrode-side porous metal 7 are disposed on the outer surfaces of the fuel-electrode layer 3 and the air-electrode layer 4, respectively; and a separator 8 is disposed on each of the outer surfaces of the fuel-electrode-side porous metal 6 and the air-electrode-side porous metal 7. Then, the solid oxide fuel cell is constructed by closely adhering them all. The pores 6a in the fuel-electrode-side porous metal 6 is partially or fully filled with a hydrocarbon reforming catalyst 10, and reforming reaction is driven by the reforming catalyst 10 before a fuel gas reaches the fuel-electrode layer 3.

Abstract: An electrode of a solid oxide fuel cell has a skeleton (11) constituted of a porous sintered compact having a three dimensional network structure, the porous sintered compact being made of an oxide ion conducting material and/or a mixed oxide ion conducting material; grains (12) made of an electron conducting material and/or a mixed oxide ion conducting material are adhered onto the surface of the skeleton; and the grains are baked inside the voids (13) of the porous sintered compact under the conditions such that the grains are filled inside the voids.

It is preferable that the electrode is used in the form such that the electrode is formed to be integrated with the electrolyte on one surface or on both surfaces of an oxide ion conducting, dense solid electrolyte layer.
