Abstract

A fuel cartridge includes an inlet manifold and a plurality of fuel beds containing a hydride material. A first end of each of the fuel beds is coupled to the inlet manifold to receive wet hydrogen via the inlet manifold. An outlet manifold is coupled to a second end of each of the fuel beds to receive dry hydrogen from the fuel beds. The fuel beds are laterally spaced from each other providing space for flow of coolant fluid therebetween. Valves may be included in the inlet and outlet manifolds.

First claim

What is claimed:

1. A fuel cartridge, comprising:
an inlet manifold;
a plurality of fuel beds containing a chemical hydride material, a first end of each of the fuel beds being coupled to the inlet manifold to receive hydrogen gas containing water vapor via the inlet manifold to react with the chemical hydride material to produce dry hydrogen gas;
an outlet manifold coupled to a second end of each of the fuel beds to receive the dry hydrogen from the fuel beds; and
wherein the fuel beds are laterally spaced from each other providing space for flow of coolant fluid therebetween to cool the fuel beds while the dry hydrogen is being produced.

2. The fuel cartridge of claim 1 , wherein each of the plurality of fuel beds comprises a fiber reinforced polymer.

3. The fuel cartridge of claim 1 , wherein the plurality of fuel beds are arranged in a rectangular staggered column array.

4. The fuel cartridge of claim 1 , wherein the fuel cartridge includes a temperature sensor configured to determine a temperature associated with the fuel cartridge.

5. The fuel cartridge of claim 4 , wherein the temperature sensor is configured to determine a temperature associated with an outer surface of the fuel cartridge.

6. The fuel cartridge of claim 4 , wherein the temperature sensor is configured to determine a temperature associated with an interior of one of the plurality of fuel beds.

7. The fuel cartridge of claim 1 , wherein the first end of each of the plurality of fuel beds includes a first gas-permeable filter supported between the input manifold and the fuel beds and wherein the second end of each of the plurality of fuel beds includes a second gas-permeable filter supported between the output manifold and the fuel beds.

8. The fuel cartridge of claim 1 and further comprising:
a first valve disposed within an input of the inlet manifold; and
a second valve disposed within an output of the outlet manifold.

9. The fuel cartridge of claim 8 wherein the first and second valves are configured to be in an open position in response to the fuel cartridge being operably coupled to an anode loop of a fuel cell based power generator and in a closed position in response to the fuel cartridge not being operably coupled to the anode loop.

10. The fuel cartridge of claim 8 wherein the first and second valves are iris valves.

11. A fuel cartridge, comprising:
an inlet valve;
a plurality of fuel beds containing a chemical hydride material;
an outlet valve;
wherein the fuel beds are spaced apart to facilitate flow of cooling fluid past the plurality of fuel beds, and
wherein each of the plurality of fuel beds is connected to the inlet valve to receive wet hydrogen gas containing water vapor via an inlet manifold and wherein each of the plurality of fuel beds is connected to the outlet valve to react with the chemical hydride material to provide dry hydrogen via an outlet manifold.

12. The fuel cartridge of claim 11 wherein the cooling mechanism includes a plurality of ducts, and wherein each of the plurality of fuel beds is separated from others of the plurality of fuel beds by at least one of the plurality of ducts.

13. The fuel cartridge of claim 11 , wherein the cooling fluid comprises air.

14. The fuel cartridge of claim 11 , wherein the fuel cartridge includes a heating mechanism configured to provide heat to the plurality of fuel beds.

15. The fuel cartridge of claim 11 , and further comprising a cooling mechanism that includes a fan configured to provide the cooling fluid.

16. The fuel cartridge of claim 15 , wherein the cooling mechanism includes a duct configured to direct airflow along the plurality of fuel beds.

17. A method, comprising:
containing a granular hydride material in a plurality of spaced apart fuel beds of a fuel cartridge;
inserting the fuel cartridge into a fuel cell based power generator o open valves associated with each of first and second ends of the fuel beds;
providing water vapor to the first end of each of the plurality of fuel beds, wherein hydrogen gas is generated by a respective reaction within each of the plurality of fuel beds to produce generated hydrogen gas;
passing the generated hydrogen gas out of the fuel cartridge; and
cooling the fuel beds by flowing coolant fluid past the outside of the spaced apart fuel beds.

18. The method of claim 17 and further comprising retaining the granular hydride material within the fuel beds via filters positioned at each of the first and second ends of the fuel beds.

19. The method of claim 17 , wherein the method includes:
sensing a temperature of the fuel cartridge; and
controlling a cooling mechanism to maintain the temperature of the fuel cartridge.
