H01M002/06

US Classification:

429 34, 429 19, 429 22, 429 38

Abstract:

In a solid-oxide fuel cell system, the electronic control unit which measures and controls temperatures, pressures, valve sequencing, valve positioning, blower power, electric output, and flows of air and fuel gas, is disposed in a “cool zone” within a structural housing. Electric leads from the control unit to the individual system components therefore do not pass through the housing. The few leads from the control unit required for connection of the fuel cell system to a load are gathered into a single electrical connector mounted through a wall of the structural enclosure.

Abstract:

A method of main reformer startup is disclosed. The method comprises introducing a first supply of fuel and a first supply of air into a micro-reformer. The first supply of fuel is increased to produce a heated reformate in the micro-reformer. The heated reformate is directed through a main reformer in order to heat the main reformer. At least a portion of the heated reformate is burned in the main reformer. A second supply of fuel and a second supply of air is introduced into the main reformer to produce a main supply of reformate. A method for maintaining a vehicle device in standby condition is also disclosed.

International Classification:

H01M 8/04
H01M 8/12

US Classification:

429 22, 429 13

Abstract:

A method and system for controlling reformate delivered to an electrochemical cell in an electric power system. The system comprises: a reformate pressure sensor disposed in the reformate and configured to measure reformate pressure; a controllable valve configured to control the flow of reformate to the electrochemical cell; and a controller coupled to the reformate pressure sensor and the controllable valve. The controller receives a reformate pressure signal from the reformate pressure sensor, a controllable valve position signal from the controllable valve, and transmits a controllable valve command to the controllable valve.

Abstract:

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.
