ABSTRACT:
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.
