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.

Abstract
Method for regenerating a fuel cell comprising the following steps in succession: - providing a fuel cell comprising: an anodic chamber (1) equipped with a dihydrogen inlet (4), a dihydrogen outlet (5), and at least one anode (6); a cathodic chamber (2) equipped with a gas inlet (7), a gas outlet (8), and at least one cathode (9); and an injecting device (10) connected to the gas inlet (7) of the cathodic chamber (2) and to the dihydrogen outlet (5) of the anodic chamber (1) or to the dihydrogen inlet (4) of the anodic chamber (1), the injecting device (10) being configured to inject dihydrogen into the cathodic chamber (2) or to block the injection of dihydrogen; and - activating the injecting device (10) so as to inject dihydrogen into the cathodic chamber (2) in order to regenerate the cathode (9) during the operation of the fuel cell. The injection of dihydrogen into the cathodic chamber (2) allows the anode (6) to be heated and it to be cleaned of organic impurities such as volatile organic compounds or carbon monoxide.
