Fuel cartridge for fuel cells

1. A fuel supply connectable to a cell, comprising:

an outer casing, wherein the outer casing is sealed;

an inner fuel container comprising fuel for the fuel cell, wherein the inner fuel container is made from a polymeric material and wherein the inner fuel container collapses or reduces its volume as fuel is withdrawn;

a valve adapted to transport the fuel to the fuel cell; and

a means for minimizing the net pressure exerted on the inner fuel container at any given time in accordance to ideal gas laws.

2. The fuel supply of claim 1 , wherein the fuel supply is connected to a pump to transport the fuel.

3. A fuel supply connectable to a fuel cell, comprising:

an outer casing, wherein the outer casing is sealed; and

an inner fuel container comprising fuel for the fuel cell, wherein the inner fuel container is made from a polymeric material and wherein the inner fuel container collapses or reduces its volume as fuel is withdrawn, and

a valve adapted to transport the fuel to the fuel cell,

wherein the inner fuel container comprises a first head space having a total pressure P 1 , Wherein a second space between the outer casing and the inner fuel container is filled with a gas to control the pressure P 1 of the inner fuel container, wherein the gas is a member selected from the group consisting of helium, neon, argon, krypton, xenon, radon, nitrogen, and carbon dioxide, and wherein the second space has a total pressure P 2 substantially in equilibrium with P 1 at any Oven time in accordance to ideal gas laws, and wherein the first head space comprises fuel vapor.

4. The fuel supply of claim 3 , wherein the gas is pressurized.

5. The fuel supply of claim 3 , wherein the gas disrupts the gradient of air from the atmosphere to the inner fuel container.

6. The Mel supply of claim 3 , wherein the fuel supply is sealed inside an outer packaging.

7. The fuel supply of claim 6 , wherein a space between the outer packaging and the fuel supply is filled with a gas, wherein the gas is a member selected from the group consisting of helium, neon, argon, krypton, xenon, radon, nitrogen, and carbon dioxide.

8. The fuel supply of claim 6 , where the space between the outer packaging and the fuel supply is vacuumed.

9. The fuel supply of claim 3 , wherein the outer casing is rigid.

10. The fuel supply of claim 3 , wherein the inner fuel container is deformable.

11. The fuel supply of claim 3 , wherein the fuel supply is connected to a pump to transport the fuel.
