  • Proton conductors
    Patent number: 8426077
    Abstract: Proton conductivity has been shown in acceptor-doped rare earth orthoniobates and tantalates (LnNbO4 and LnTaO4) at high temperatures and in a humid atmosphere. The use of the materials as an electrolyte in a laboratory-scale fuel cell and water vapor sensor has been demonstrated. Results for Ca-doped LaNbO4 are given as examples.
    Type: Grant
    Filed: December 22, 2005
    Date of Patent: April 23, 2013
    Assignee: Universitetet I Oslo
    Inventors: Truls Norby, Reidar Haugsrud, Stefan Marion, Mari-Ann Einarsrud, Kjell Wiik, Øystein Andersen, Ruth Astrid Strøm, Tor Grande
