  • Nanocomposite electrode material for proton conducting fuel cell
    Patent number: 10381656
    Abstract: An electrode includes a proton conducting electrolyte phase, an electronic conducting phase, and a metal or metal alloy catalyst in contact with each of the phases. The electronic conducting phase is infiltrated with the proton conducting electrolyte phase such that the phases form a solid nanocomposite with bulk electronic conductivity.
    Type: Grant
    Filed: November 19, 2015
    Date of Patent: August 13, 2019
    Assignee: University of Tennessee Research Foundation
    Inventors: Alexander B. Papandrew, Ramez A. Elgammal

  • Electrolytic generation of graphite
    Patent number: 9290853
    Abstract: The embodiments herein relate to methods and apparatus for forming graphitic material from a carbon oxide feedstock in an electroplating chamber containing molten inorganic carbonate as electrolyte. Carbon dioxide flows into a reaction chamber containing one or more cathodes, one or more anodes, and a molten carbonate electrolyte. The carbon dioxide and/or carbonate reduces at the cathode to form graphitic material, which may be removed from the surface of the cathode through various mechanisms. The graphitic material is then separated out from the electrolyte.
