Disclosed herein are aspects of an adaptive purge technique for purging fuel cells adjusts the time delay between subsequent purges based in part on one or more parameters of the fuel cells. A difference between two like parameters is measured before and after actuation of a valve used to permit entry of a purge gas. The degree of difference between the two parameters is used to determine a time delay, i.e., a time at which the valve should again be actuated to permit the next purge of the fuel cell. In additional to the time delay, the parameters may be used to determine a time interval, or duration, in which the valve is actuated to remain open during a purge event.
