PROBLEM TO BE SOLVED: To provide a fuel cell stack clamping device for constantly keeping contact pressure in the stack while automatically correcting the contact pressure, and outputting a large clamping load with small force by using the own weight of the stack. SOLUTION: This fuel cell stack clamping device is composed of: end plates of which the inside surfaces are formed into vertical surfaces to tightly fit to both sides of a fuel cell stack module, and the outside surfaces are formed into first oblique sides; an oblique device for housing the end plates while coming into surface contact with the first oblique sides; and first and second unidirectional load control plates connected to upper and lower surfaces of the end plates to impose the load of the fuel stack only in the inside direction of the stack.
