PROBLEM TO BE SOLVED: To reduce the thermal deflection in an excessive operation time, and to heat the cells evenly for a short time, by providing a pair of current drawing-out plates and a pair of insulating plates having a necessary property, and realizing the fastening and the heating while maintaining a soft structure. SOLUTION: To this fastening and heating device 10, a pair of current drawing-out plates 12 contacting to the upper and the lower surfaces of a laminate fuel cell 7; a pair of insulation members 14 contacting to the upper and the lower surfaces of the plates 12; a pair of fastening plates 16 contacting to the upper and the lower surfaces of the members 14; a gas header 18; and a gas heater 20; are provided. And at least to one side of the plates 12, a gas passage 12b communicated to the gas header 18 is formed through a felxible piping 19. The plates 12 which consist of a copper, a stainless steel, or the like have the flexibility and the heat conductivity almost same as a single separator, while the members 14 which consist of a fire- resisting material, a hard heat insulating material, or the like have a sufficient insulating property and flexibility. The thickness of the plates 12 is made two to three times of the thickness of the separator, the surfaces contacting to a battery 7 are finished at a high plane accuracy, and current terminals 12a are formed integrally or welded to the plates 12. |
