Abstract
A fuel cell stack manifold having an ejector function of which the manufacturing cost and the weight can be reduced by optimizing hydrogen supply and recirculation channels and removing other members. hardware without a separate ejector structure for additionally attaching an ejector, of which the productivity can be improved by removing from an ejector assembly process. The fuel cell system minimizes joints through which hydrogen may leak, by implementing a new structure of a manifold added with an ejector function by integrally forming/manufacturing a stack manifold having a venturi and diffuser structure and adding a nozzle thereto.
