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.

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.

Abstract: A vehicle includes a fuel cell, an inlet valve, a purge valve, and a controller. The fuel cell has an anode side configured to receive hydrogen. The inlet valve is configured to open to deliver the hydrogen to the anode side. The purge valve is configured to open to purge water and nitrogen from the anode side. The controller is programmed to, operate the inlet valve to inject hydrogen into the anode side via opening the inlet valve followed by closing the inlet valve. The controller is further programmed to, in response to a concentration of the hydrogen in the anode side being less than threshold, open the purge valve to purge water and nitrogen from the anode side.

Abstract: A fuel cell system in a vehicle includes a fuel cell stack and a cooling system for cooling the fuel cell stack. The cooling system has a radiator and at least one pump configured to supply coolant to the fuel cell stack. A controller operates the cooling system to actively cool the fuel cell stack while the vehicle is shut down in response to conditions indicating that the next time the vehicle will be started, it will be a cold start. The controller can then, subsequent to initiating the cooling, purge the fuel cell stack.
