PROBLEM TO BE SOLVED: To structure a small size and light weight fuel cell stack. SOLUTION: A laminated body 14 laminated with unit cells 12 is housed in a case 20 together with current collector electrodes 16a, 16b, insulating plates 58a, 58b and an end plate 18. Cone disc springs 22 are provided between the end plate 18 and the case 20, and the laminated body 14 is pressure supported by elastically energizing (pressing on) the end plate 18 by the cone disc springs 22. Further, the end plate 18 is supported to the case 20 by engaging the protrusion member 68 jointed to the case 20 in free sliding with a side groove 64 provided at the both ends of the end plate 18, thereby, the end plate 18 is displaced as it is guided by the protrusion member 68 when the cone disc springs 22 are compressed or expanded. |
