摘要： A conductive and tabular separator is inserted into the gap between the fuel electrode layer of an i-th power generating cell and the oxidizer electrode layer of an (i+l)-th power generating cell adjacent to the fuel electrode layer. A fuel supply passage is so formed on one face of each of these separators that a fuel gas flows radially from almost the center of the fuel electrode layer to its edge. An oxidizer supply passage is so formed on the other face that an oxidizer gas outgoes almost uniformly in a shower toward the oxidizer polar layer. Thus, all of the surfaces of the power generating cells contribute to power generation to increase the frequency of collision between the fuel gas and the fuel electrode layer and that between the oxidizer gas and the oxidizer electrode layer, and to improve the generation efficiency.

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.
