ABSTRACT:
A system for optimizing the purge cycle of a fuel cell stack responsive to the performance of the fuel cell. The system includes a controller that measures a process parameter indicative of the rate at which water is being produced in the fuel cell. If the measured value exceeds a threshold value, then the purge assembly is automatically actuated.
