Herein disclosed is a cell stack assembly structure for a fuel cell, comprising a plurality of units each of which is composed of a plurality of cell elements laminated in advance and which are stacked and fastened under a predetermined pressure to construct a cell stack assembly. Each of a plurality of end plates is interposed between any adjacent two of the units. Removable pressure means are provided for fastening under a predetermined pressure any two of the end plates, that are positioned at the two ends of a corresponding one of the units.
