Abstract: A multi-stage in-line cartridge ejector for a fuel cell system is provided to improve whole performance of a system, to reduce the number of component and costs, and to ensure system simplification for cold starting and reduction of time. A multi-stage in-line cartridge ejector(12) for a fuel cell system is installed between a hydrogen tank(10) and a fuel cell stack(11) of the fuel cell system. At the same time, a hydrogen recycling line(13) is installed at the multi-stage in-line cartridge ejector. Thus, inhalation flux from the hydrogen recirculation line side is increased by using hydrogen flow of high pressure supplied to the fuel cell stack while passing through the multi-stage in-line cartridge ejector.
