Abstract: This specification describes a system and method for controlling the voltage produced by a fuel cell. The system involves providing a bypass line between an air exhaust from the fuel cell and an air inlet of the fuel cell. At least one controllable device is configured to allow the flow rate through the bypass line to be altered. A controller is provided to control the controllable device. The method involves varying the rate of recirculation of air exhaust to air inlet so as to provide a desired change in fuel cell voltage.

Abstract: An electrical power supply system has a fuel cell module and a battery. The fuel cell can be selectively connected to the battery system through a diode. The system preferably also has a current sensor and a controller adapted to close a contactor in a by-pass circuit around the diode after sensing a current flowing from the fuel cell through the diode. The system may also have a resistor and a contactor in another by-pass circuit around the diode. In a start-up method, a first contactor is closed to connect the fuel cell in parallel with the battery through the diode and one or more reactant pumps for the fuel cell are turned on. A current sensor is monitored for a signal indicating current flow through the diode. After a current is indicated, a by-pass circuit is provided around the diode.

Abstract: A fuel cell module has a hydrogen recirculation pump and a controller. The controller receives a signal indicating the response of the pump to changes in the density or humidity of gasses in the hydrogen recirculation loop. The controller is programmed to consider the signal in controlling one or more balance of plant elements that effect the removal of water from the stack. In a process for operating the fuel cell module, the signal is considered when controlling one or more balance of plant elements that effect the removal of water from the stack. For example, an increase in current drawn from a constant speed or voltage recirculation pump indicates an increase in humidity and suggests that water should be removed from the stack, for example by increasing a coolant temperature set point.

Abstract: The present disclosure is generally directed to a design geometry of a venturi or an ejector that is optimized in systems and methods for increasing the operating range of the venturi or the ejector in a fuel cell system. The present disclosure is also generally directed to fuel cell systems and methods for sizing and/or integrating a recirculation blower with a venturi or an ejector in a fuel cell or fuel cell stack. The present disclosure is further generally directed to systems and methods of operating a fuel cell system comprising more than one venturi or ejectors during transient operations.

Abstract: A humidification device includes a tubular mass exchanger fluidically coupled to receive intake air stream and transfer intake air stream to an intake air inlet of a fuel cell stack. The humidification device includes a housing configured to house the tubular mass exchanger to define a void therebetween. The housing defines at least one housing inlet opening fluidically coupled to direct an exhaust air stream output by the fuel cells tack into the void. The housing defines at least one housing outlet opening fluidically coupled to direct the exhaust air stream away from within the housing. The tubular mass exchanger is configured to extract water vapor from the exhaust air stream and transfer the extracted water vapor to the intake air stream flowing within the tubular mass exchanger to humidify the intake air stream to generate a humidified intake air stream.

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.
