Abstract

An apparatus for fueling a fuel-cell-powered device having a profile and a fuel inlet. The apparatus comprises at least one fuel port having an outlet and at least one adaptor associated with the fuel port. The adaptor is configured to receive the fuel-cell-powered device. Means for releasably and sealingly engaging the fuel inlet of the fuel-cell-powered device to the outlet of the fuel port are also provided. The outlet of the fuel port is operative to dispense fuel when it is in sealed engagement with the fuel inlet of the fuel-cell-powered device.

Claims

1. An apparatus for fueling at least three fuel-cell-powered devices, each device having a profile and a fuel inlet, the apparatus comprising:

a housing defining at least three device adaptor recesses, each device adaptor recess configured for accepting a device adaptor;

at least three fuel ports, each of the ports having an outlet;

at least three device adaptors each configured to fit within any of the three device adaptor recesses, including a first device adaptor, a second device adaptor and a third device adaptor, wherein each of the first, second, and third device adaptors are adjacent to one of the fuel ports and include a device recess for receiving a body of one of the devices, wherein the device recess of the first device adaptor has a shape that is disparate from the shape of the device recesses of the second and third device adaptors;

at least three seals, each seal disposed to releasably establish a sealed fluidic connection between the fuel inlet of one of the devices and the outlet of one of the fuel ports;

wherein each of the fuel ports are operative to dispense fuel when the inlet of the fuel-cell-powered device is in sealed engagement with the outlet of the at least one fuel port.

2. An apparatus according to claim 1 wherein each device adaptor includes a mechanism for constraining a device.

3. An apparatus according to claim 1 comprising an on-board fuel source in fluid connection with the at least one fuel port.

4. An apparatus according to claim 1 comprising an external fuel source in fluid connection with the at least one fuel port.

5. An apparatus according to claim 1 wherein the at least one fuel port comprises a check valve, whereby fuel can be dispensed when the check valve is open and fuel is not dispensed when the check valve is closed.

6. An apparatus according to claim 5 wherein the at least one device adaptor comprises an actuator operably connected to the check valve and moveable between an engaged position causing the check valve to open, and a released position causing the check valve to close, whereby when the profile of the fuel-cell-powered device is fully received within the device recess of the at least one device adaptor the actuator moves to the engaged position, and when the profile of the fuel-cell-powered device is no longer fully received within the device recess of the at least one device adaptor the actuator moves to the released position.

7. An apparatus according to claim 1 comprising a purge valve connected upstream from one of the fuel ports.

8. An apparatus according to claim 1 comprising a pressure relief device configured to open to relieve pressure within the apparatus when the pressure within the apparatus reaches or exceeds a threshold pressure.

9. An apparatus according to claim 1 comprising a fuel pressure regulator.

10. An apparatus according to claim 1 wherein the apparatus is portable.

11. An apparatus according to claim 1 wherein the fuel is a gas.

12. An apparatus according to claim 11 wherein the fuel is hydrogen.

19. The apparatus of claim 1 wherein each of the at least three adaptors can be releasably fastened within any of the at least three adaptor recesses.

13. A method of fueling a fuel-cell-powered device having a profile and a fuel inlet, the method comprising:

providing a fuel source;

providing an apparatus including

a housing defining at least three adaptor recesses, each adaptor recess configured for accepting a device adaptor;

at least three fuel ports, each of the ports having an outlet and

at least three device adaptors each configured to fit within any of the three device adaptor recesses, including a first device adaptor, a second device adaptor and a third device adaptor, wherein each of the first, second, and third device adaptors are adjacent to one of the fuel ports and include a device recess for receiving a body of a fuel-cell-powered device,

wherein the device recesses of the first adaptor has a shape that is disparate from the shape of the device recesses of the second and third adaptors;

releasably and sealingly engaging the outlet of one of the fuel ports with the fuel inlet of a first fuel-cell-powered device; and

allowing fuel to flow from the engaged fuel port to the fuel-cell-powered device.

14. The method of claim 13 further comprising releasably and sealingly engaging a second fuel-cell-powered device to one of the fuel ports, the second fuel-cell-powered device having a body with a profile that is disparate from the profile of the body of the first fuel-cell-powered device.

15. The method of claim 14 further comprising releasably and sealing engaging a third fuel-cell-powered device to one of the fuel ports, the third fuel-cell-powered device having a body profile that is disparate from the profiles of either the bodies of the first fuel-cell-powered device or the second fuel-cell-powered device.

16. The method of claim 13 wherein each device adaptor includes a constraining mechanism adapted for constraining a fuel-cell-powered device while it is being refueled.

17. The method of claim 13 wherein each device adaptor includes an actuator.

18. The method of claim 13 wherein each of the at least three adaptors can be releasably fastened within any of the at least three adaptor recesses.

20. A refueling system for fueling fuel-cell-powered devices, the system comprising:

a housing defining at least two adaptor recesses, each adaptor recess configured for accepting a device adaptor;

at least two refueling ports, each of the ports include an outlet;

a first device adaptor and a second device adaptor, wherein each of the first and second device adaptors are configured to be releasably held in either of the two adaptor recesses and wherein each of the first and second device adaptors define a device receptacle having a cross-section shaped to accept a fuel-cell-powered device and wherein the shape of the cross-section of the device receptacle defined by the first device adaptor is disparate from the shape of the cross-section of the device receptacle defined by the second device adaptor.

21. The refueling system of claim 20, wherein the first and second device adaptors each include a mechanism for constraining the received fuel-cell-powered device.

22. The refueling system of claim 20, further comprising an on-board fuel source in fluid connection with the refueling port.

23. The refueling system of claim 20, wherein the first and second device adaptors each include an actuator and the refueling port includes a check valve, and wherein each actuator of the first and second device adaptors can be operably connected to the check valve and moveable between an engaged position causing the check valve to open and a released portion causing the check valve to close.

24. The refueling system of claim 20, further including a fuel cylinder housed within the housing and wherein the housing includes a removable panel that provides access for removing the fuel cylinder.
