FUEL CELL EJECTOR

An ejector housing defines a suction chamber, a mixing chamber, and a diffuser nozzle. The diffuser nozzle defines a restrictive orifice, and a diffuser outlet. A first port supplies an entrained fluid to the mixing chamber. First and second motive fluid nozzles include a first valve and a second valve selectively supply first and second portions of the motive fluid to the mixing chamber through first and second motive fluid nozzle outlets. A controller selectively opens and closes the first valve and the second valve to controller the level of fluid flow through the first port.
