  • Electrolytic production of hydrogen
    Patent number: 4737249
    Abstract: A process for the electrochemical production of hydrogen from an aqueous alkaline electrolyte characterized by the use as a cathode of a material having the general formula AB.sub.5 H.sub.x wherein A is one or more of rare earth metals and calcium, B is nickel or cobalt and x is a number, generally from 4 to 8 characteristic of saturation of the AB.sub.5 -compound with hydrogen. The hydrogen is generated at a relatively low overpotential and thus at high efficiency.
    Type: Grant

    Date of Patent: April 12, 1988
    Assignee: Inco Alloys International, Inc.
    Inventors: Vance R. Shepard, Jr., Dale E. Hall, John T. Arms, William D. K. Clark
  • Hydrogen sorbent composition
    Patent number: 4433063
    Abstract: A hydrogen sorbent composition is provided which is comprised of a hydridable material such as LaNi.sub.5 encradled throughout a porous, fiber-containing polymeric composition.
    Type: Grant

  • Production of a cell electrode system
    Patent number: 4396693
    Abstract: An improvement in the production of polymer-bonded cell electrodes comprises forming a particulate material which can be developed into a shaped polymeric system comprising an electrode active material encradled in a porous, fiber-containing, polymeric composition. In a preferred embodiment, the polymeric system is developed as a thin, flexible electrode.
    Type: Grant

    Date of Patent: August 2, 1983
    Assignee: MPD Technology Corporation
    Inventors: Philip Bernstein, James P. Coffey, Alan E. Varker, John T. Arms, William D. K. Clark
  • Production of a polymeric active composition
    Patent number: 4385019
    Abstract: A process is provided for forming a polymeric material which can be developed into a shaped polymeric structure comprising an active material encradled in a porous, fiber-containing polymeric composition. In the process, the active material is mixed with a tripartite system comprising a fibrillatable polymer, a support-contributing polymer and a pore-former. When such a system is mixed and developed with an active material, such as LaNi.sub.5, an active composition is produced which may be used, for example, as a hydrogen collecting or storing material.
