Abstract

The disclosure relates to an unmanned aerial vehicle, wherein a fuel cell system component provides a structural component of the vehicle. In some instances propulsion modules affixed to wings are oriented so as to provide airflow to plates of a fuel cell via air inlets for each fuel cell provided at the forward surface of each wing, a fuel cell system component forming a portion of the body and wherein the air inlets are unblocked during flight, each propulsion module is configured to provide air as an oxidant to a fuel cell via the air inlets.

First claim

The invention claimed is:

1. An aerial vehicle having a fuel reservoir forming a portion of the aerial vehicle's support structure comprising:
propulsion modules affixed to wings;
a fuel cell having vertical plates oriented from top to bottom surface of each wing;
air inlets for each fuel cell provided at the forward surface of each wing;
a fuel cell system component forming a portion of the body;
wherein the air inlets are unblocked during flight;
wherein each propulsion module is configured to provide air as an oxidant to a fuel cell via the air inlets;
a fuel cell system component provides a structural load bearing component of the aerial vehicle; and,
wherein the fuel cells form a fuel cell stack which generates power.

2. The aerial vehicle of claim 1 further comprising the fuel cells are formed as unitary components with the wings; and,
the surfaces of end plates of each of the fuel cells are aerodynamically shaped to at least partially provide the functionality of the wing structure.

3. The aerial vehicle of claim 2 further comprising at least one fuel cell on the upright portion of the tailplane configured with air inlets for said fuel cell provided at the forward surface of the tailplane.

4. The aerial vehicle of claim 3 further comprising the fuel cells are formed as unitary components with the tailplane; and,
the surfaces of end plates of each of the fuel cells are aerodynamically shaped to at least partially provide the functionality of the tailplane structure.

5. The aerial vehicle of claim 1 wherein the plates are one of bipolar and monopolar.

6. The aerial vehicle of claim 1 wherein the fuel cell system component is one of a fuel cell, a fuel generator, a coolant structure, a fuel reservoir, and a reactant reservoir.

7. The aerial vehicle of claim 2 further comprising a plurality of at least one type of fuel cell system component distributed about the vehicle.

8. The aerial vehicle of claim 4 further comprising a plurality of at least one type of fuel cell system component distributed about the vehicle.

9. The aerial vehicle of claim 1 wherein the fuel cell component is a fuel supply module.

10. The aerial vehicle of claim 2 wherein a separate fuel supply module is provided to each fuel cell.

11. The aerial vehicle of claim 2 wherein a centralized fuel supply module is used to supply fuel to the fuel cells.

12. The aerial vehicle of claim 4 wherein a separate fuel supply module is provided to each fuel cell.

13. The aerial vehicle of claim 4 wherein a centralized fuel supply module is used to supply fuel to the fuel cells.

14. The aerial vehicle of claim 2 wherein the air inlets are fanless and rely on the motion of the vehicle through the air when in flight to direct air into the forward-facing air inlets.

15. The aerial vehicle of claim 14 further comprising airflow from propellers to direct air into the forward-facing air inlets.

16. The aerial vehicle of claim 4 wherein the air inlets are fanless and rely on the motion of the vehicle through the air when in flight to direct air into the forward facing-air inlets.

17. The aerial vehicle of claim 16 further comprising airflow from propellers to direct air into the forward-facing air inlets of a portion of the fuel cells distributed on the vehicle.
