Abstract

A fuel storage device in accordance with a present invention includes a fuel storage area and at least one of a fuel heater, a byproduct heater and a valve.

Claims

1. A fuel storage device, comprising:

a fuel storage area;

a fuel outlet;

a fuel heater having an inlet operably connected to the fuel storage area and an outlet operably connected to the fuel outlet;

a byproduct storage area;

a byproduct inlet operably connected to the byproduct storage area; and

a byproduct heater having an inlet operably connected to the byproduct inlet and an outlet operably connected to the byproduct storage area.

2. A fuel storage device, comprising:

a fuel outlet;

means for storing fuel;

means for receiving energy from an outside source and transferring heat to the fuel as the fuel flows from the means for storing fuel to the fuel outlet; and

means for storing byproduct.

3. A fuel storage device as claimed in claim 2, further comprising:

a byproduct inlet operably connected to the means for storing byproduct.

4. A fuel storage device as claimed in claim 3, further comprising:

means for receiving energy from an outside source and transferring heat to the byproduct as the byproduct flows from the byproduct inlet to the means for storing byproduct.

5. A fuel storage device for use with fuel cell that generates heat, the fuel storage device comprising:

a fuel storage area;

a fuel outlet;

a fuel heater having an inlet operably connected to the fuel storage area. an outlet operably connected to the fuel outlet, and means for transferring heat from the fuel cell to fuel; and

a byproduct storage area that is isolated from the fuel storage area.

6. A fuel storage device as claimed in claim 5, further comprising:

a housing;

wherein the fuel storage area is defined by a first flexible container located within the housing and the byproduct storage area is defined by a second flexible container located within the housing.

7. A fuel storage device, comprising:

a fuel storage area;

a fuel outlet; and

a fuel heater having an inlet operably connected to the fuel storage area. an outlet operably connected to the fuel outlet, non-hollow heat pipe. and a plurality of heat transfer fins extending from the heat pipe;

wherein

the fuel heater includes a housing and a plurality of walls within the housing;

the heat pipe and heat transfer fins are located within the housing such that the walls are located between respective pairs of heat transfer fins; and

there are gaps between the walls and the heat transfer fins that together define a fuel path that extends from the inlet to the outlet.

8. A fuel storage device, comprising:

a fuel storage area;

a fuel outlet;

a fuel heater having an inlet operably connected to the fuel storage area, an outlet operably connected to the fuel outlet, non-hollow heat pipe and a plurality of heat transfer fins extending from the heat pipe; and

a byproduct storage area that is isolated from the fuel storage area.

9. A fuel storage device, comprising:

a fuel storage area;

a fuel outlet;

a fuel heater having an inlet operably connected to the fuel storage area, an outlet operably connected to the fuel outlet, non-hollow heat pipe, and a plurality of heat transfer fins extend from the heat pipe; and

a housing;

wherein the fuel storage area is defined by a first flexible container located within the housing and the byproduct storage area is defined by a second flexible container located within the housing.
