HIGH EFFICIENCY HUMIDITY MANAGEMENT SYSTEM FOR FUEL CELLS AND HIGHER-TEMPERATURE ELECTROCHEMICAL SYSTEMS

A humidity transfer assembly includes a pressure vessel and a humidity transfer device disposed in the pressure vessel. The humidity transfer device includes an enclosure, a first inlet line fluidly coupled to the enclosure and configured to supply anode exhaust thereto, a first outlet line fluidly coupled to the enclosure and configured to output anode exhaust therefrom, and a second inlet line fluidly coupled to the enclosure and configured to supply feed gas thereto. The humidity transfer device is configured to transfer steam from anode exhaust to feed gas and to output feed gas into the pressure vessel.
