Patent ID: 7291410

Claim:
A liquid fuel reservoir for a liquid fuel cell, said liquid fuel reservoir comprising a container comprising walls defining a container volume capable of holding a liquid fuel, a first port through a wall of the container capable of discharging the liquid fuel to a location exterior of the container volume, at least one extremity remote from the first port and a pressurized pallet or bladder comprising a compressible porous material, wherein the first port has inner and outer ends; and a wicking structure within the container volume and into which the liquid fuel can wick by capillary action and from which the liquid fuel may subsequently be discharged, the wicking structure (a) having a solid wicking structure volume which is no more than 50% of the container volume; (b) being in fluid communication with the first; and (c) extending from proximate the at least one extremity to proximate the inner end of the first port in order to be able to place the at least one extremity in fluid communication with the first port, in any orientation of the container, and at substantially any stage of liquid fuel depletion, to permit liquid fuel located proximate the at least one extremity to be wicked to the first port.
