In a plurality of solid oxide fuel cells (1) each including: a circular cell plate (2) holding single cells (6) as a solid oxide fuel cells and having a gas introducing opening (21) and a gas exhausting opening (22) in a central section; a circular separator plate (3) having a gas introducing opening (31) and a gas exhausting opening (32) in a central section and joined to the cell plate; and a central channel member (5) which is located in a space (S) formed by steps of the cell plate and the separator plate and performs supply and exhaust of fuel gas, a plurality of the solid oxide fuel cells are stacked facing a same direction, a interspace between each adjacent pair of the overlapping fuel cells serves as an air channel (15), sealing members (16) (17) allowing the gas intruding openings of the cell plate and the separator plate to airtightly communicate with each other and allowing the gas exhausting openings of the cell plate and the separator plate to airtightly communicate with each other are provide between the center parts of the fuel cells, and the stacked fuel cells are fastened and fixed by a bolt (18) at the center.
