PURPOSE:To prevent generation of a warp by forming a stacking element layer which is placed on both sides of unit cell by bonding the first stacking element comprising a porous carbon substrate having grooves on its one side and the second stacking element comprising smooth carbon plate with adhesive. CONSTITUTION:A unit cell 11 is formed with a negative electrode 6 comprising a porous substrate having grooves 4 for negative active material on its one side and a catalyst layer on its other side, a positive electrode 9 comprising a flat porous carbon substrate 7 having a catalyst layer 8 on its one side, and a matrix layer 10 containing electrolyte. A stacking element layer 12 is formed by bonding the first stacking element 1 comprising porous substrate having grooves for positive active material on its one side and the second stacking element comprising smooth carbon plate with an adhesive 3. The unit cells are stacked with the stacking element layer 12 interposed. Thereby, a warp of the stacking element layer 12 is prevented and breakage of the unit cells 11 during stacking operation is also prevented. |
