<P>PROBLEM TO BE SOLVED: To provide a fuel cell stack structural body capable of materializing enhancement of output density, and also materializing enhancement of starting performance by reducing a heat capacity. <P>SOLUTION: This fuel cell stack structural body is provided with a laminate 2 formed by laminating a plurality of solid electrolyte fuel cells 10 each of which is equipped with a circular thin plate-shaped separator 11, a circular thin plate-shaped cell plate 13 holding a unit cell 12 and having the fringe part bonded to the fringe part of the separator 11, and a center passage component 14 located between respective center parts of the separator 11 and the cell plate 13 to supply and discharge an anode gas to and from the inside of a space formed between the separator 11 and the cell plate 13 through its anode gas introducing passage 14a and anode gas discharging passage 14b. This laminate 2 is housed in a heat insulating vessel 4 together with a coned disc spring 3, and the laminate 2 is pressurized by a heat insulating lid 6 fixed to the heat insulating vessel 4 in the laminated direction of the solid electrolyte fuel cells 10. <P>COPYRIGHT: (C)2007,JPO&INPIT |
