Abstract
A fuel cartridge with a deformable inner fuel container connectable to a fuel cell is disclosed. The pressure in the inner fuel container is controlled.
Claims11
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is made from a polymeric material and wherein the inner fuel container collapses or reduces its volume as fuel is withdrawn;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.

- 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is made from a polymeric material and wherein the inner fuel container collapses or reduces its volume as fuel is withdrawn, and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 P1, Wherein a second space between the outer casing and the inner fuel container is filled with a gas to control the pressure P1 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 P2 substantially in equilibrium with P1 at any Oven time in accordance to ideal gas laws, and wherein the first head space comprises fuel vapor.
