    摘要: A parallel dual stack fuel cell system having anode recirculation includes a first fuel cell stack and a second fuel cell stack. Each of the first and second fuel cell stacks includes a gas outlet line connected to an anode outlet unit. The anode outlet unit functions to release wet H2/N2 gaseous mixture from the system. A second water separator is provided between the anode outlet unit and gas inlet lines to the first and second fuel cell stacks to increase removal of water droplets prior to a recirculation pump.

    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.
