Abstract: The present disclosure relates to systems and methods of using a proportional control valve in a fuel cell stack system. The fuel cell stack system, may comprise a fuel cell stack including an anode with an anode inlet and an anode outlet, and a cathode with a cathode inlet and a cathode outlet, and a control valve, which controls the flow of a fuel into the anode. The flow of fuel may be based on a pressure differential measured across any two of the anode inlet, the anode outlet, the cathode inlet, and the cathode outlet.
