  • Electronically conductive ceramics for high temperature oxidizing environments
    Patent number: 4564567
    Abstract: A high temperature, ceramic composition having electronic conductivity as measured by resistivity below about 500 ohm-cm, chemical stability particularly with respect to cathode conditions in a molten carbonate fuel cell, and composed of an alkali metal, transition metal oxide containing a dopant metal in the crystalline structure to replace a portion of the alkali metal or transition metal.
    Type: Grant
    Filed: November 10, 1983
    Date of Patent: January 14, 1986
    Assignee: The United States of America as represented by the United States Department of Energy
    Inventors: Gene H. Kucera, James L. Smith, James W. Sim
  • Glass electrolyte composition
    Patent number: 4544614
    Abstract: An ionically conductive glass is disclosed for use as electrolyte in a high temperature electrochemical cell, particularly a cell with sodium anode and sulfur cathode. The glass includes the constituents Na.sub.2 O, ZrO.sub.2, Al.sub.2 O.sub.3 and SiO.sub.2 in selected proportions to be a single phase solid solution substantially free of crystalline regions and undissolved constituents. Other advantageous properties are an ionic conductivity in excess of 2.times.10.sup.-3 (ohm-cm).sup.-1 at 300.degree. C. and a glass transition temperature in excess of 500.degree. C.
