Abstract
Systems and methods of managing the voltage of fuel cells during no-load or low load events are disclosed. The systems may employ one or more valves such as an inlet and outlet valve for metering the fuel (e.g., hydrogen) and/or oxidant (e.g., oxygen) provided to the fuel cell. The voltage or voltage rise may be limited by starving the fuel cell of, for example, oxygen. A controller may be employed for controlling the one or more valves during a no-load or low load event such as start-up, idling, or stopping.
