Fuel supply for a fuel cell
First Claim
1. A fuel supply cartridge for a fuel cell, the cartridge comprising:
- a liquid storage area containing a liquid reactant;
a reaction area containing a solid reactant, the reaction area configured to allow liquid reactant to be pumped from the liquid storage area into the reaction area at which time that the liquid reactant reacts with the solid reactant to produce reaction components;
a product collection area configured to the reaction components from the reaction area;
three barriers, each barrier individually separating;
(i) the liquid storage area from the product collection area;
(ii) the liquid storage area from the reaction area; and
(iii) the reaction area from the product collection area;
one or more barriers moving to simultaneously increase a volume of one area while decreasing the volume of another area; and
,an outer container with an interior volume that substantially encloses the reaction area, liquid storage area, and product collection area;
wherein the product collection area is fluidly coupled to the reaction area by a channel and includes a product filter that adsorbs one or more of the reaction components;
wherein the product filter has different adsorption characteristics along its distance from the channel.

Abstract
The present invention discloses a fuel supply for a fuel cell, the fuel cell including a liquid storage area that includes a liquid reactant, a reaction area that includes a solid reactant, wherein the liquid reactant is pumped into the reaction area such that the liquid reactant reacts with the solid reactant to produce reaction components, a product collection area that receives the reaction components, a barrier, and a container with an interior volume that substantially encloses the reaction area, liquid storage area, product collection area. The barrier separates and defines several of the aforementioned areas, and moves to simultaneously increase the product collector area and decrease the liquid storage area as the liquid reactant is pumped from the liquid storage area and the reaction components are transferred into the product collection area.
