Zusammenfassung:	An apparatus for a fuel cell stack assembly is provided to minimize stress concentration applied to the fuel cell stack and to improve tightening efficiency by combining a fuel cell stack to an intersectional space of two U-shaped connecting body and fixing the connecting body to end plates. An apparatus for a fuel cell stack assembly formed by alternatively laminating a membrane-electrode assembly and a separator comprises a pair of end plates(210,230) which is mounted on both ends of the fuel cell stack and supports the fuel cell stack; a U-shaped first connector(213) which is fixed to tighteners(211a,211b) by penetrating both ends of the connecting body through one of a pair of end plates; and a U-shaped second connector(233) which is fixed to tighteners(231a,231b) by penetrating both ends through the other of a pair of end plates.
