NOVELTY - The fuel supply comprises a liquid storage area, a reaction area (400), a product collection area, a first barrier (300) such as a bag, a rigid container (200), a second barrier such as an elastic membrane, a liquid dispenser, a flexible channel, and a third barrier. The liquid storage area includes a liquid reactant such as water, is contained in the product collection area, and is under vacuum. The reaction area includes a solid reactant (500) such as a compacted pill of sodium borohydride and a biasing mechanism, and is contained in the liquid storage area.    USE - The fuel supply is useful for a fuel cell such as hydrogen fuel cells, as pure-fuel storage such as a tank of hydrogen gas, and as a fuel generator, where the fuel cell is useful in power portable consumer devices such as laptop computers and cell phones, portable media players, power medical devices, heating/ cooling devices and vehicles.    ADVANTAGE - The portable compact fuel supply provides the fuel with high fuel stability, contains both the reactants and waste products in the single container, is easily integrated into the consumer devices, minimizes the required size of the fuel supply cartridge, and increases lifespan of the fuel cell.    DETAILED DESCRIPTION - The fuel supply comprises a liquid storage area, a reaction area (400), a product collection area, a first barrier (300) such as a bag, a rigid container (200), a second barrier such as an elastic membrane, a liquid dispenser, a flexible channel, and a third barrier. The liquid storage area includes a liquid reactant such as water, is contained in the product collection area, and is under vacuum. The reaction area includes a solid reactant (500) such as a compacted pill of sodium borohydride and a biasing mechanism, and is contained in the liquid storage area. The liquid reactant is pumped into the reaction area such that the liquid reactant reacts with the solid reactant to produce reaction components. The product collection area receives the reaction components, is fluidly coupled to the reaction area by the flexible channel, and includes a product filter such as a nylon foam that adsorbs liquid and solid components of the reaction components. The first barrier: separates the liquid storage area from the product collection area; 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; encloses the liquid storage area; divides the internal volume into a first volume and a product collection volume that is fluidly coupled to the first volume; and inversely varies the first volume and the product collection volume as the reaction components flow into the product collection volume. The container with an interior volume encloses the reaction area, liquid storage area and product collection area, includes a product outlet fluidly coupling the interior volume to an exterior of the container, and is fluidly sealed except for the product outlet. The interior volume is occupied by the reaction area, liquid storage area and product collection area. The second barrier encloses/envelopes the solid reactant such that the second barrier collapses as the reaction components are produced; has the first volume that separates the liquid storage area and the reaction area; and moves with the first barrier to inversely vary the first volume and the product collection volume as the reaction components flow into the product collection volume. The biasing mechanism biases the solid reactant towards the pumped liquid reactant, encloses the solid reactant such that the biasing mechanism collapses as the reaction components are produced, and envelops the reaction area. The solid reactant includes a reaction product path that moves reaction products to the product collector, and includes a helix channel disposed around the solid reactant that guides the reaction composition to the product collection area. The reaction product path includes a channel disposed on a surface of the solid reactant, a channel disposed through the solid reactant, the helix channel disposed around the solid reactant, a contained region disposed around the solid reactant, and a conduit abutting the solid reactant. The liquid dispenser: pumps the liquid reactant from the liquid storage area into the reaction area and liquid reactant to the solid reactant surface to produce reaction components that flow into the product collection volume; includes a nozzle through the second barrier through which the liquid reactant is pumped into the reaction area; comprises an inlet such as a tube fluidly coupled to the liquid storage area, an outlet fluidly coupled to the reaction area, a surface such as a flexible diaphragm in fluid communication with the inlet and outlet, a first valve fluidly coupled to the inlet and a second valve fluidly coupled to the outlet; and is coupled to the solid reactant and fluidly coupled to the liquid reactant. The reaction components include a gaseous component. The product filter comprises of a series of open-cell foams with different pore sizes and a hydrogen gas separator. The pore sizes of the foams decrease with increasing distance from the flexible channel. The third barrier encloses the product collection area, and expands as the product collector area increases. The surface moves to pump the liquid reactant from the liquid storage area to the reaction area, and reciprocates to pump the liquid reactant. The liquid dispenser inlet is placed in the liquid storage area. The tube is fluidly coupled to a flexible plastic thread with a length as long as a longest dimension of the liquid storage area and a diameter smaller than the length of the tube. The fuel supply is coupled to a fuel cell. The first volume includes the liquid storage area containing the liquid reactant and the reaction area containing the solid reactant, and collapses as reaction components flow into the product collection volume. The internal volume is defined by interior walls of the container. The second volume includes the series of open-cell foams with different pore sizes and the hydrogen gas separator fluidly coupled to the product outlet. The pore sizes of the foams decrease with increasing distance from the fluid couple with the first volume. The foam expands and adsorbs reaction components as the reaction components flow into the product collection volume. The product filter comprises of open-cell foam. The foam pore size is small in the compressed state, and expands to a significantly larger pore size in the expanded state.
