<P>PROBLEM TO BE SOLVED: To provide a fuel cell stack suitably eliminating variation of surface pressure in the laminated cell stack. <P>SOLUTION: This is the fuel cell stack 1 in which a polyelectrolyte membrane is clipped by a pair of electrodes having catalyst reaction layer, a unit cell is constructed by arranging a conductive separator supplying a fuel gas to one of the electrodes and an oxidizer gas to the other electrode, and a laminated body 2 laminating a plurality of the unit cells is tightened by end plates 3 arranged on both ends. Wire members 5 which wind over a plurality of rolling rollers arranged at the both end plates 3 are wound two or more times over the laminated body 2 and tightens it in the direction that the end plates 3 approach mutually. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
