Abstract
A fuel cell system has a fuel cell stack including a plurality of fuel cells and an anode injector system, and a controller programmed. The controller, responsive to an amplitude of cyclic changes in voltage of at least some of the fuel cells exceeding a threshold, a frequency of the cyclic changes being within a predetermined range of a frequency associated with the anode injector system, and the voltage being less than a predetermined value, disables the fuel cell stack.
