摘要： A system and method for reducing RH cycling of the membranes in a fuel cell stack. A control algorithm damps a power request signal using a first order filter during low power transients so that the fuel cell stack continues generating power at a higher rate than is requested. The excess power generated by the stack is used to recharge a battery in the fuel cell system. The damped power signal is weighted so that more fuel cell stack power is provided for a low battery state of charge unless stack power is provided for a high battery state of charge.

摘要： A process for controlling the length of a purge and the purge rate of a fuel cell stack at system shut-down so as to provide the desired amount of stack humidity. The membrane humidification is measured at system shut-down by a high frequency resistance sensor that detects membrane humidification and provides the measurement to a controller. The controller controls the compressor that provides cathode input air to the fuel cell stack so that the time of the purge and the flow rate of the purge provide a desired membrane humidity for the next start-up.

摘要： A fuel cell system that employs a recuperative heat exchanger to provide additional cooling for the compressed charge air applied to the cathodes of the fuel cells in the fuel cell stack. The cathode exhaust gas is applied to the recuperative heat exchanger so that the cathode exhaust gas cools the charge air heated by the compressed air. A cathode exhaust gas expander is provided in combination with the recuperative heat exchanger that uses the energy in the heated cathode exhaust gas to power the charge air compressor. An anode exhaust gas combustor can be provided that burns residual hydrogen in the anode exhaust gas to further heat the cathode exhaust gas before it is applied to the expander.

摘要： A system and method for limiting the output current of a fuel cell stack as the stack degrades overtime. A look-up table identifies a predetermined voltage set-point for stack current density. A first comparator provides a voltage difference signal between the set-point and the stack voltage. The voltage difference signal is provided to a controller, such as a proportional-integral controller, that provides a current limiting signal. The current limiting signal and a current request signal are provided to a second comparator that selects which signal will be used to limit the maximum output current of the stack. A polarization curve estimator estimates parameters of the stack that will change over the life of the stack. The parameters are provided to a gain scheduler that provides gains to the controller that are based on where in the life of the stack it is currently operating.

摘要： A method of operating the fuel cell stack having an anode side and a cathode side by flowing hydrogen into the anode side and flowing air into the cathode side. The fuel cell produces electricity that is used to operate a primary electrical device. To shut down the stack in one embodiment, the primary electrical device is disconnected from the stack. The flow of air into the cathode side is stopped and positive hydrogen pressure is maintained on the anode side. The fuel cell stack is shorted and oxygen in the cathode side is allowed to be consumed by hydrogen. The inlet and outlet valves of the anode and the cathode sides are closed. Thereafter, the flow of hydrogen into the anode side is stopped and the flow of exhaust from the cathode side is stopped.

摘要： A method for providing a fast and reliable start-up of a fuel cell system. The method uses a stack voltage response to a load to assess if hydrogen and oxygen are being sufficiently distributed to all of the fuel cells by coupling an auxiliary load to the fuel cell stack until a predetermined minimum cell voltage has been reached or a first predetermined time period has elapsed. The method then determines whether a minimum cell voltage has dropped to a first predetermined voltage and, if so, reduces the maximum power allowed to be below the first predetermined voltage value, determines whether the minimum cell voltage in the stack is below a second predetermined voltage, or determines whether the minimum cell voltage drop rate is greater than a predetermined voltage drop rate. If none of these conditions are met, the method returns to loading the stack with system components.

摘要： A method for reconditioning a fuel cell stack. The method includes determining whether fuel cell stack reconditioning is desired based on predetermined reconditioning triggers, determining if predetermined system constraints are met that will allow reconditioning of the fuel cell stack to occur, and determining whether previous reconditioning processes have been attempted, and if so, whether predetermine reconditioning limits have been exceeded during those attempts. The reconditioning process is initiated if one or more of the reconditioning triggers has occurred, the predetermined system constraints are met and the predetermined reconditioning limits have not been exceeded. The reconditioning process increases the humidification level of a cathode side of the fuel cell stack over the humidity level of the cathode side during normal operating conditions and waiting for cell membranes in the fuel cell stack to saturate after the humidification level of the cathode has increased.
