    摘要： A solid-oxide fuel cell system having a relatively large primary fuel cell sub-assembly for steady-state operation and a relatively small secondary fuel cell sub-assembly which is rapidly heatable to a threshold operating temperature to a) produce usable power in a short time period, b) cascade a hot exhaust into the primary fuel cell sub-assembly to assist in preheating thereof, and c) provide steam into the primary fuel cell sub-assembly to prevent coking of the anodes thereof. As the primary sub-assembly reaches its threshold temperature, it too begins to generate electricity and continues to self-heat and to be heated by the secondary sub-assembly. Preferably, the secondary sub-assembly continues to provide electricity in complement with the primary sub-assembly until the primary sub-assembly reaches full power, at which time the secondary sub-assembly may be shut down or switched to standby status for fuel efficiency, as desired.

    摘要： A fuel cell system in accordance with the invention includes a single, central electronic controller (CPU) for controlling at least the Air Handling sub-system, the Reformer sub-system, the Power Electronics sub-system, and the Customer Interface sub-system. The central controller provides a central location for easier serviceability; increases data transport efficiency by eliminating lengthy links between distributed controllers; eliminates the need for multiple mechanical enclosures; allows for controller thermo conditioning in one mechanical enclosure; and reduces parasitic power losses by employing a single power supply.

    摘要： A control system for controlling energization of a plurality of valves in a vehicle hydraulic system. The control system includes a plurality of sensors for measuring various dynamic conditions and operational aspects of the vehicle, a signal processing circuit coupled to the plurality of sensors for determining a desired energization of the plurality of valves dependent upon measurements by at least a portion of the plurality of sensors, and a driver circuit coupled to the signal processing circuit for generating, responsive to the desired energization of the plurality of valves as determined by the signal processing circuit, a control signal to energize the plurality of valves to the desired energization. The control system receives inputs from the plurality of vehicle sensors. These inputs are processed, and the processed inputs and signals derived from the inputs are forwarded to the driver circuit for use in generating a control signal for operating the vehicle valve system. In a particular embodiment, the valve system is controlled to operate a plurality of hydraulic actuators to provide a desired configuration of the vehicle.
