Abstract
An ejector has a two-stage nozzle structure. The ejector is installed on a fuel cell recirculation line to supply new hydrogen and a recirculation gas. The ejector includes a housing having a first orifice defined therein and a poppet that is disposed in the housing and having a second orifice defined therein. A damage prevention member is disposed on a surface of the poppet to contact an inner surface of the housing, in which the damage prevention member contacts or is separated from the inner surface of the housing based on a pressure applied to the poppet.
