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.

A method for controlling the purge cycle of a fuel cell stack, the method comprising:providing a fuel cell stack including at least one fuel cell adapted to produce an electric current and a purge assembly including at least one purge valve;measuring a value of a process parameter

[ I claim:] [1.]1. A method for controlling the purge cycle of a fuel cell stack, the method comprising:providing a fuel cell stack including at least one fuel cell adapted to produce an electric current and a purge assembly including at least one purge valve;measuring a value of a process parameter representative of the performance of the fuel cell stack;comparing the value of the process parameter to a determined value; andactuating the purge assembly if the value of the process parameter exceeds the determined value.
