ABSTRACT:
An integrated charge air heat exchanger for use in a vehicle fuel cell system is provided. The integrated charge air heat exchanger includes a plurality of coolant conduits adapted for a coolant fluid to flow therethrough. The integrated charge air heat exchanger further includes a plurality of heating elements and a plurality of fin elements. One heating element is disposed on a first surface of each of the coolant conduits, and one of the fin elements is disposed on a second surface of each of the coolant conduits. A method for heating the coolant fluid in a first operational mode and cooling a charge air stream in a second operational mode is also provided.
