Abstract: Discloses a means for enhancing the transfer of hydrogen to and from solid hydridable material in a container and enhancing heat transfer to and from said hydridable material. The means whereby these enhancements are accomplished comprises a series of metallic trays arranged in non-nesting configuration in the hydrogen container.

Abstract: A composite electrode having a structural electrode member with at least a portion of one surface of the electrode member constructed from a continuous matrix of an anodically passivatable metal infiltrated by a metal capable of forming an electroconductive oxide and having the infiltrating metal at the electrode surface oxidized such that an electric current path is provided through the oxidized surface of the matrix metal. In one embodiment the matrix metal is an electrochemical valve metal, e.g., titanium and the infiltrating metal is lead. Applications for the composite electrode include battery grids and electrochemical processing electrodes.

Abstract: A process of producing copper-cored titanium wire of less than 16 gauge comprising cold drawing, in a multiplicity of passes, a titanium tube filled with copper powder.

Abstract: A bipolar electrode support structure for use in a lead acid battery is constituted by a porous matrix of valve metal, impregnated with lead or a lead alloy, and is provided on at least one surface thereof with a rim-portion at which little or no lead is exposed. The rim-portion is used to maintain an electrolyte-tight seal in operation.

Abstract: Discloses a hydrogen storage module comprising a fluted tube section closed at each end with a gas permeable porous plug and containing a metal adapted to form a hydride or the hydride of such metal.

Abstract: Discloses the use of collapsible hollow structures within a mass of metal-hydride material used in a pressure vessel for storing hydrogen.

Abstract: Discloses the use of spatially extended particles of a solid characterized by a low apparent density distributed within a mass of metal hydride material used in a pressure vessel for storing hydrogen.

Abstract: A hydrogen-storage vessel having particles of hydrideable alloy in a multiplicity of closed containers permeable to hydrogen within the vessel to prevent localized pressure effects acting against the walls of the vessel.
