<P>PROBLEM TO BE SOLVED: To provide a tightening technology of a fuel cell stack in which the fuel cell stack will not become large-sized, and in which discovery of a deteriorated point of the fuel cell stack caused by reduction in the visible region by visual contact will not become difficult. <P>SOLUTION: The fuel cell stack 100A is equipped with a laminate 10, in which a membrane electrode assembly and a separator are alternately laminated. A circumscribed rectangular part 11, dented in a rectangular form, is installed on a side face of the laminate 10. A tightening member 30 for applying a tightening load in the laminating direction of the laminate 10 is housed in the circumscribed rectangular part 11. This fuel cell stack 100A is improved in the tightening force, since a tightening film which is a polymer resin film is wound around the side face of the laminate 10 in a bandage state, as a whole. <P>COPYRIGHT: (C)2009,JPO&INPIT |
