NOVELTY - The cell (1) has a female penetration screw-hole (95a) formed in opposing parts (91a, 92a) such that a center shaft becomes vertical with respect to an upper surface or lower surface of a laminated body (8). A front end contacts on the upper surface or lower surface of the laminated body, while screwing together in the screw-hole. The laminated body is tightened along lamination direction by tightening to the screw-hole, where thickness of a connection part (93a) is set larger than that a cross-sectional area divided by thread diameter and smaller than lateral width of the connection part.    USE - Planar view square shape fuel cell. Uses include but are not limited to a polymer electrolyte fuel cell, phosphoric acid form fuel cell, molten carbonate fuel cell and a solid oxide fuel cell.    ADVANTAGE - The laminated body can be clamped along the lamination direction by tightening the screw part attached to the opposing parts, so that compressive stress acts on a screw part, thus preventing reduction and creep rupture of creep strain of the screw part. The cell allows tractive force similar to the screw part to be added to a connection part as reaction by which compressive force is added to the screw part, so that design freedom is high, thus reducing influence of the creep of the fastening part compared with the screw part. The laminated body is firmly fixed by the fastening part even if a fuel cell forms a gas flow path in a bolt without influencing bolting intensity of the laminated body, thus improving freedom degree of the design, which forms the gas flow path. The cell is formed in an inner side of an angular part, and the connection part is formed on a smooth curved surface, so that slack of the screw part at time of electric power generation is reduced. The cell provides a clearance gap between the connection part and the laminated body, so that the clearance gap can be reliably formed by making an inner side of the angular part into the curved surface, thus preventing electrical short.    DETAILED DESCRIPTION - The connection part is formed in U-shape.
