摘要： 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. The electrode drastically improves the electrode properties and alleviates the thermal shock and the thermal strain to a great extent. 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.

摘要： 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.
