Abstract: A method and system for recirculating an anode off gas in a fuel cell assembly includes receiving anode off gas and generating steam therefrom. A first flow of the steam is directed to a first control valve and a second flow of the steam is directed to a second control valve. The first and second control valves control steam that flows through the superheater and connects to a first ejector and a second ejector. In response to an operating parameter being equal to a threshold value, the first control valve is opened to allow the steam to pass through the superheater and subsequently at least partially drive the first ejector.
