PURPOSE:To reduce the number of production processes and to enhance output density by connecting plate type unit cells in parallel in the shape of a polygon. CONSTITUTION:A unit cell consists of a gas permeable base plate 21, and an oxygen electrode 23, a solid electrolyte 22, and a fuel electrode 24 stacked on one side of the base plate 21 on order, and current collector 34 made of heat resistant metal which are arranged at upper and lower ends of the base plate 21. By forming the unit cell in the shape of a plate, production process is simplified compared with that of a cylindrical unit cell. By forming a polygonal cell with plate-shaped unit cells, a cell comprising, for example, four rectangular unit cells connected in parallel is obtained. A solid electrolyte fuel cell having high output density is obtained by connecting these unit cells in series and parallel. |
