  • Publication number: 20050092618
    Abstract: The present invention discloses a process and apparatus for removing sodium and chloride ions from an aqueous sodium chloride solution, such as seawater or brine. The process includes electrolyzing aqueous sodium chloride to remove chloride and sodium ions in the form of chlorine gas and sodium metal. Preferably, a photovoltaic device, such as a triple junction amorphous silicon solar cell, provides the electrical energy for the electrolysis. The process utilizes electrode material that facilitates the production of chlorine gas and inhibits the evolution of hydrogen from the aqueous sodium chloride solution. The sodium is deposited onto a metal surface having a high hydrogen overpotential to produce sodium amalgam. The processed solution from the electrolysis has a reduced sodium chloride content and may be further processed to produce fresh water for human consumption or agricultural purposes.

  • Publication number: 20050079129
    Abstract: The present invention discloses a method and system for charging a metal hydride bed, wherein the metal hydride bed contains a hydrogen storage material. The metal hydride bed is charged using a chemical hydride slurry having a metal hydride, a stabilizing agent and water. As the slurry contacts the metal hydride bed, a catalyst in the metal hydride bed promotes a reaction between the metal hydride of the slurry and water. The reaction produces atomic hydrogen and byproducts. At least a portion of the atomic hydrogen is absorbed by the hydrogen storage material and the remaining atomic hydrogen is disposed from the system or used as fuel in a hydrogen fueled apparatus, such as a fuel cell.

  • Publication number: 20050058892
    Abstract: Mechanically and thermally improved rechargeable batteries, modules and fluid-cooled battery pack systems. The battery is prismatic in shape with an optimized thickness to width to height aspect ratio which provides the battery with balanced optimal properties when compared with prismatic batteries lacking this optimized aspect ratio. The optimized thickness, width and height allow for maximum capacity and power output, while eliminating deleterious side affects. The battery case design allows for unidirectional expansion which is readily compensated for by applying external mechanical compression counter to that direction. In the module, the batteries are bound within a module bundling/compression means under external mechanical compression which is optimized to balance outward pressure due to expansion and provide additional inward compression to reduce the distance between the positive and negative electrodes, thereby increasing overall battery power.

    Abstract: A fuel cell utilizing parallel flow of a hydrogen stream, an oxygen stream, and an electrolyte solution with respect to the electrodes, while maintaining mechanical support within the fuel cell. The fuel cell utilizes encapsulated electrodes to maintain a high air flow rate and low pressure throughout the fuel cell. The fuel cell is also designed to maintain mechanical support within the fuel cell while the electrodes expand and contract in response to the absorption of oxygen and hydrogen. Gas is predistributed by the compression plates and electrode plates to supply the electrodes with high concentrations of oxygen from air.
