The apparatus includes a liquid permeable pouch that defines a cavity for maintaining an anhydrous hydride reactant, wherein the cavity comprises a cross-section such that a point within the cross-section is separated from a perimeter of the liquid permeable pouch by no more than double the permeation distance, and a cartridge configured to receive the liquid permeable pouch and a liquid reactant such that at least a portion of the liquid permeable pouch is submerged in the liquid reactant. The system includes a plurality of pouches formed from two rectangular sheets of liquid permeable material, and each pouch has a width selected such that each point within a cross-section is separated from the sheets by no more than double the permeation distance. The method includes joining the sheets, forming one or more seals to define a cavity, disposing anhydrous hydride within the cavity, and sealing the opening.

What is claimed is: 1. An apparatus to promote a substantially complete reaction of an anhydrous hydride reactant, the apparatus comprising: a liquid permeable pouch that defines a cavity, the liquid permeable pouch having at least one wall formed from material configured to permit passage of a liquid from one side of the material to the other side; a solid anhydrous hydride reactant disposed within the cavity, the solid anhydrous hydride reactant having a liquid permeation distance; wherein the cavity comprises a cross-section such that each point within the cross-section is separated from a perimeter of the liquid permeable pouch by no more than double the permeation distance; a cartridge configured to receive the liquid permeable pouch and a liquid reactant such that at least a portion of the liquid permeable pouch is in contact with the liquid reactant. 2. The apparatus of claim 1, wherein the permeation distance comprises a distance the liquid reactant is capable of traveling in reacted hydride. 3. The apparatus of claim 1, further comprising a plurality of tubular liquid permeable pouches in a side-by-side configuration. 4. The apparatus of claim 3, wherein the cartridge is cylindrical and wherein the plurality of liquid permeable pouches is rolled, a longitudinal axis of the rolled plurality of liquid permeable pouches oriented coaxial with a longitudinal axis of the cartridge. 5. The apparatus of claim 3, wherein the plurality of liquid permeable pouches are disposed within the cartridge such that the plurality of liquid permeable pouches form one or more liquid channels directing a flow of liquid reactant around the plurality of liquid permeable pouches. 6. The apparatus of claim 5, further comprising a plurality of liquid conduits radially spaced about a longitudinal axis of the cartridge, each liquid conduit positioned along side at least one tubular liquid permeable pouch. 7. The apparatus of claim 1, wherein the cartridge is configured to receive a plurality of liquid permeable pouches having different lengths, the liquid permeable pouches stacked and arranged in alternating courses such that a course gap between two stacked liquid permeable pouches does not line up with the gap in an adjacent course of liquid permeable pouches. 8. The apparatus of claim 1, wherein the liquid permeable pouch is formed substantially of a material having a maximum wicking distance of about 0.3 inches per minute in a direction opposite a gravitational pull. 9. The apparatus of claim 1, wherein the liquid permeable pouch is formed substantially of a material configured to maintain structural integrity through temperatures in the range of between about 5 degrees and about 200 degrees Celsius. 10. The apparatus of claim 1, wherein the liquid permeable pouch is formed of a material configured to maintain structural integrity and contribute substantially no contaminates to the anhydrous hydride reactant during a reaction of the anhydrous hydride reactant. 11. The apparatus of claim 1, wherein the liquid permeable pouch comprises a material formed substantially of between about 75 percent polyester and about 100 percent polyester and between about 25 percent rayon and about 0 percent rayon. 12.
