Method and system for supplying hydrogen for use in fuel cells
InactiveUS6348278B1Reduce hydrogen concentrationImprove concentrationElectricity cogenerationRegenerative fuel cellsHydrogenCombustor
The present invention provides a method and system for efficiently producing hydrogen that can be supplied to a fuel cell. The method and system of the present invention produces hydrogen in a reforming reactor using a hydrocarbon stream and water vapor stream as reactants. The hydrogen produced is purified in a hydrogen separating membrane to form a retentate stream and purified hydrogen stream. The purified hydrogen can then be fed to a fuel cell where electrical energy is produced and a fuel cell exhaust stream containing water vapor and oxygen depleted air is emitted. In one embodiment of the present invention, a means and method is provided for recycling a portion of the retentate stream to the reforming reactor for increased hydrogen yields. In another embodiment, a combustor is provided for combusting a second portion of the retentate stream to provide heat to the reforming reaction or other reactants. In a preferred embodiment, the combustion is carried out in the presence of at least a portion of the oxygen depleted air stream from the fuel cell. Thus, the system and method of the present invention advantageously uses products generated from the system to enhance the overall efficiency of the system.

Electric vehicle having multiple-use APU system
ActiveUS20060219448A1Reducing net metered electricityIncrease powerAuxillary drivesBatteries circuit arrangementsElectricityFuel cells
During periods of vehicle inactivity, a vehicle-based APU electric generating system may be coupled into a regional electric grid to send electricity into the grid. A currently-preferred APU is a solid oxide fuel cell system. When a large number of vehicles are thus equipped and connected, substantial electric buffering can be effected to the grid load. A vehicle-based APU can also function as a back-up generator to a docking facility in the event of power failure of the grid. Gaseous hydrocarbon is readily supplied by pipe in many locations as a commercial and residential heating fuel source, and a hydrocarbon reformer on the vehicle can be attached to the fuel source, enabling an APU to operate as a stationary power source indefinitely. An optional storage tank on the vehicle may be refueled with gaseous fuel, for example, while the battery is being electrically recharged by the grid.

Fuel cell system capable of reducing electric power loss
A fuel cell system minimizes the power loss that may occur in a conduction passage during supply of electric power from a fuel cell to a load. A bypass connects between the input of a DC / DC converter and the output thereof, and therefore supplies power generated by the fuel cell to an inverter, bypassing the DC / DC converter. A changeover switch selectively changes the connection of the output of the fuel cell between the connection to the input of the DC / DC converter and the connection to the bypass. When the fuel cell is connected to the DC / DC converter, the power from the fuel cell is supplied to the inverter or a battery via the DC / DC converter. When the fuel cell is connected to the bypass, the power from the fuel cell is supplied to the inverter, bypassing the DC / DC converter. A cutoff switch disconnects the output of the battery from a connecting line. That is, the cutoff switch disconnects the battery from the inverter, the bypass and the like when turned off. When turned on, the cutoff switch 41 connects the battery to those components.

The preferred mode of using the regenerative fuel cell is as a battery charger since this application is able to use a much smaller fuel cell than is required to power the vehicle.
