Abstract: A fuel cell air management system includes a compressor receiving ambient air at a compressor inlet and supplying compressed air at a compressor outlet. A mechanical power transmission is connected to an electric machine. The mechanical power transmission is operatively connected to the compressor. An expander is operatively connected to the mechanical power transmission. A recuperator is connected to the compressor outlet. The recuperator includes a recuperator inlet and a recuperator outlet. An intercooler is coupled to the recuperator outlet. A fuel cell stack is connected to an intercooler outlet. The fuel cell stack includes a fuel cell outlet connected to the recuperator and the recuperator includes an exhaust connected to the expander. A water separator is connected to an outlet of the expander. The water separator is coupled to a pump metering a specified dose of water to a specified location selected from the compressor inlet, the compressor outlet, the recuperator outlet or combinations thereof.

Abstract: A recirculation gas flow control and distribution assembly that includes an electric motor and a pump coupled to the electric motor. The pump includes a pump housing with a pump inlet and a pump outlet. The pump inlet is fluidly connected to a recirculated gas. At least one nozzle is directly connected to the pump housing. A passage is formed in the pump housing and nozzle linking the pump inlet to the nozzle. An injector is coupled to the nozzle, the injector is fluidly connected to a fuel. A valve is disposed in the passage, the valve is movable between open and closed positions. The recirculated gas is selectively passed to the pump outlet and fuel is selectively feed into the nozzle.
