    摘要: A fuel cell system includes a fuel cell stack that receives a cathode feed gas and has an exhaust stream and a heat transfer stream flowing therefrom. A charge-air heat exchanger enables heat transfer between the heat transfer stream and the cathode feed gas. The charge-air heat exchanger also enables heat transfer between the heat transfer stream and the cathode feed gas to compensate for the adiabatic cooling effect. Furthermore, the charge-air heat exchanger vaporizes the liquid water to provide water vapor. The water vapor humidifies the cathode feed gas.

    摘要: A system and method for improving air humidification for fuel cell applications includes a fuel cell stack having a cathode inlet and a cathode outlet. The cathode inlet receives an oxidant. A humidifier humidifies the oxidant prior to delivery of the oxidant to the cathode inlet. An injection nozzle is provided, and a volume of water substantially vaporized by the injection nozzle reduces a temperature of the oxidant and increases a water transfer rate of the humidifier. The injection nozzle can be positioned either directly upstream of the humidifier in the oxidant inlet line or in a stack cathode outlet line which is directed into the humidifier.
