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: An exhaust gas recirculation pump for an internal combustion engine that includes an electric motor assembly having an electric motor disposed within an electric motor housing. A roots device is coupled to the electric motor. The roots device includes a housing defining an internal volume. Rotors are disposed in the internal volume and connected to the electric motor. A bearing plate is attached to the housing wherein the bearing plate and an outer cover attached to the bearing plate defines an oil cavity. A transmission assembly is positioned on an opposing side of the housing relative to the electric motor and in the oil cavity.
