  • Patent number: 8357213
    Abstract: 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.

  • Publication number: 20090053134
    Abstract: A process, composition of matter, and apparatus for generating hydrogen are disclosed. The process includes providing an anhydrous hydride, forming a mixture of the hydride with an activating agent, and introducing a liquid reactant to the mixture to produce hydrogen. The mixture includes activating agent in the range of between about 20 to about 80 percent by dry weight.

  • Patent number: 7438732
    Abstract: A fuel cartridge for a hydrogen generating system having a cartridge containing a substantially anhydrous chemical hydride reactant. A plurality of liquid conduits extends into the cartridge and each of the liquid conduits has a length and a plurality of liquid distribution apertures formed along the length. The liquid distribution apertures have a diameter of less than approximately 1 mm. The chemical hydride reactant forms a bed and the liquid conduits extend along at least half of a length of the bed.
