Title: FUEL CELL CONTAMINANT REMOVAL METHOD
Abstract:
An example method of operating a fuel cell system includes calculating the rate of water produced in the fuel cell stack, determining the rate of water exiting the system, and controlling the condenser temperature to maintain the cathode gas exit temperature from the condenser below the temperature required to maintain water balance in the fuel cell system. The method collects the condensed vapor as water and purges a portion of the collected water containing contaminants from the system.
