PURPOSE:To enable a cell to be subjected to required surface pressure even if its end plate is made of carbon with low rigidity, by arranging rigid restrainers on the end plate. CONSTITUTION:In an unit cell, cooling plates 2 are interposed every time a plurality of elementary cells are piled in a block and both end plates 3, 4 are made of carbon material. The face of end plate 3 is provided 4 pairs of two grooves 3e, 3f running through along said face and the face of end plate 4 is provided with two grooves 4e, 4f in the similar configuration respectively. Then, clamping bars 13, 14 are inserted in the coupling parts 15e of a clamping crew 15 serving as a clamping member, clamping bars and clamping screws are coupled together by setting pins 15p to pass through respective pin holes 13h, 14h of clamping bars 13, 14 and holes 15h of coupling parts 15e, the clamping screw 15 is clamped by a turn buckle 15t, thus an assigned surface pressure being applied to the unit cell via clamping bars 13, 14. |
