    摘要： 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. The fluid-cooled battery pack includes; 1) a battery-pack case having coolant inlet and outlet; 2) battery modules within the case such that the battery module is spaced from the case walls and from other battery modules to form coolant flow channels along at least one surface of the bundled batteries; and 3) at least one coolant transport means. The width of the coolant flow channels allows for maximum heat transfer. Finally the batteries, modules and packs can also include means for providing variable thermal insulation to at least that portion of the rechargeable battery system which is most directly exposed to said ambient thermal condition, so as to maintain the temperature of the rechargeable battery system within the desired operating range thereof under variable ambient conditions.

    摘要： 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. The sodium amalgam is removed from the aqueous sodium chloride solution and transported to and coupled against an air depolarizing fuel cell in water to produce electrical power with the sodium air fuel cell, power that may be used to operate the apparatus or other machinery. The product of the reaction between the sodium amalgam and the fuel cell is sodium hydroxide that may be reacted with the chlorine gas to produce sodium hypochlorite.

    摘要： 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.
