Abstract: Disclosed is a separator assembly for a fuel cell and a fuel cell stack including the same. The separator assembly includes (I) a plate-shaped first separator including a first reaction area where a flow path to which a reaction gas or a coolant flows on a center thereof and first manifolds to which the reaction gas or the coolant is introduced or discharged to opposite side areas of the first reaction area, and (ii) a plate-shaped second separator integrated with the first separator by bonding and including a second reaction area corresponding to a position where the first reaction area is formed and second manifolds communicating with the first manifolds. The first and second separators may have at least a portion of an inner edge of the respective first and second manifolds that are bent, thereby being disposed on an interface between the first and second separators.
