PURPOSE:To apply even pressure onto many cells of a lamination body even when they are piled in a vertical direction by dividing the lamination body into several blocks in the direction of lamination and making it possible to adjust pressure in the direction to the lamination for each block. CONSTITUTION:Respective lamination body blocks 11 are formed by piling unit cells 21 in multiple layers through the interposition of separators 22. Cylinder-shaped bodies 41 installed for respective lamination blocks of the fuel cell lamination body move up or down when the cylinder-shaped bodies 41 are rotated. Consequently, when coil springs 44 can be pressed or expanded so that clamping force working between clamping plates 12 may become at given values, the coil springs 44 can maintain the surface pressure of the lamination body even in the face of deformation of electrolyte layers 25 due to temperature increases. |
