PURPOSE:To uniformly compress a cell over the whole face and make it small- sized by inserting hollow plates storing a porous heat insulating material and sealed inside the upper and lower presser plates respectively and applying the fastening force to the cell by the increase of the internal pressure of the hollow plates due to the rise of the temperature. CONSTITUTION:Thin plate-shaped hollow plates 16 storing a porous heat insulating material in them are inserted between the upper and lower holders 10 and 11 and presser plates 12 and 13. When a cell is operated, the temperature rises, the pressure in the hollow plates 16 is increased, the presser plates 12 and 13 are deflected to the outside, the holders 10 and 11 are compressed to a cell stack S side. The sufficient face pressure can be secured at the center portion, the cell is uniformly compressed over the whole face, thereby the whole cell can be made small-sized. |
