Abstract
An electric power generation cellis constituted by arranging a fuel electrode layeron one side of a solid electrolyte layerand an air electrode layeron the other side of the solid electrolyte layer. The solid electrolyte layeris constituted of an oxide ion conductor mainly composed of a lanthanum gallate based oxide. The fuel electrode layeris 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, 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, and accordingly can actualize a solid oxide type fuel cell excellent in electric power generation efficiency.
