  • FUEL CELL AND ELECTROLYZER HOTBOX MODULE USING CONDUCTIVE ZIRCONIA STACKS
    Publication number: 20230170494
    Abstract: Modular pressurized hotbox for use and substitution in a variety of pressurized electrochemical applications to include reversible solid oxide electrolyzer and fuel cells, energy storage systems, renewable fuel production, solid-state hydrogen pumping and liquefaction, and oxygen transport membranes. This is enabled by mixed electronic and ionic conducting compositions of vanadia-yttria and vanadia-calcia stabilized zirconia and a dry powder method of manufacture for ceramic core stacks.
    Type: Application

  • Nanocrystalline alpha alumina and method for making the same
    Patent number: 10562784
    Abstract: A process for producing metastable nanocrystalline alpha-alumina (?-Al2O3) having particle sizes smaller than 12 nm. Starting crystallites of ?-Al2O3 having a particle size larger than 12 nm, typically on the order of about 50 nm, are ball-milled at low temperatures to produce a nanocrystalline ?-Al2O3 powder having a particle size of less than 12 nm, i.e., below the theoretical room temperature thermodynamic size limit at which ?-Al2O3 changes phase to ?-Al2O3, wherein the powder remains in the ?-Al2O3 phase at all times.
