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.
