The fuel-cell battery pack for an electric propulsion vehicle includes at least one fuel-cell stack and a casing containing the fuel-cell stack. The casing includes at least one opening providing access to a housing. The fuel-cell stack is inserted into the opening by one of its ends such that one of the two end plates of the fuel-cell stack is located within the housing whilst the other end of the fuel-cell stack protrudes out of the opening. The end plate which is located outside of the casing has a peripheral rim provided to be kept in abutment against the periphery of the opening. Finally, the inlets and outlets for the reactive anode gas, the reactive cathode gas and the cooling fluid are arranged on the end plate which is located outside of the casing.
