Claims
- 1. An electrical power system within the hull of a small watercraft comprising:
a PEMFC; a hydrogen supply system to supply hydrogen to the PEMFC; an oxygen supply system to supply oxygen to the PEMFC; and, a rechargeable battery to be recharged from at least a portion of the output of the PEMFC.
- 2. The electrical power system of claim 1 further comprising a propulsion module to receive electrical power provided by at least one of the PEMFC and the rechargeable battery.
- 3. The electrical power system of claim 1 wherein the hydrogen supply system further comprises at least one pressurized hydrogen storage tank.
- 4. The electrical power system of claim 1 wherein the hydrogen supply system further comprises a reformation means, whereby hydrogen is generated through the reformation of hydrogen rich fuels.
- 5. The electrical power system of claim 1 further comprising a DC/DC converter through which electrical power from the PEMFC is converted to a selected DC.
- 6. The electrical power system of claim 1 further comprising an inverter through which electrical power from the PEMFC is converted to a selected AC.
- 7. The electrical power system of claim 1 further comprising;
an inverter through which electrical power from the PEMFC is converted to a selected AC; and, a DC/DC converter through which electrical power from the PEMFC is converted to a selected DC.
- 8. The electrical power system of claim 1 further comprising a controller whereby the recharging of the battery from the electricity produced by the PEMFC is controlled.
- 9. The electrical power system of claim 8 further comprising a sensor which provides information to the controller about the charge of the battery.
- 10. The electrical power system of claim 1 further comprising a through the hull heat exchange means.
- 11. The electrical power system of claim 10 wherein the through the hull heat exchange means is a fuel cell heat exchanger thermally connected to a heat exchange region.
- 12. The electrical power system of claim 2 further comprising at least one controller whereby the flow of electricity to the propulsion module can be varied.
- 13. The electrical power system of claim 1 further comprising a DC/DC converter through which electrical power from at least on one of the rechargeable battery and the PEMFC is converted to a selected DC.
- 14. The electrical power system of claim 1 further comprising an inverter through which electrical power from at least one of the rechargeable battery and the PEMFC is converted to a selected AC.
- 15. An electrical propulsion system within the hull of a small watercraft comprising:
a PEMFC; a hydrogen supply system; an oxygen supply system; a rechargeable battery to be recharged from the output of the PEMFC; and, a propulsion module to receive electrical power provided by the rechargeable battery.
- 16. The electrical power system of claim 15 wherein the hydrogen supply system further comprises at least one pressurized hydrogen storage tank.
- 17. The electrical power system of claim 15 wherein the hydrogen supply system further comprises a reformation means, whereby hydrogen is generated through the reformation of hydrogen rich fuels.
- 18. The electrical power system of claim 15 further comprising a DC/DC converter through which electrical power from the PEMFC is converted to a selected DC.
- 19. The electrical power system of claim 15 further comprising an inverter through which electrical power from the rechargeable battery is converted to a selected AC.
- 20. The electrical power system of claim 15 further comprising a controller whereby the recharging of the battery from the electricity produced by the PEMFC is controlled.
- 21. The electrical power system of claim 20 further comprising a sensor which provides information to the controller about the charge of the battery.
- 22. The electrical power system of claim 15 further comprising a through the hull heat exchange means.
- 23. The electrical power system of claim 22 wherein the through the hull heat exchange means is a fuel cell heat exchanger thermally connected to a heat exchange region.
- 24. The electrical power system of claim 15 further comprising at least one controller whereby the flow of electricity to the propulsion module can be varied.
