  • Cathode layer including ionic conductor material and electronic conductor material
    Patent number: 11502306
    Abstract: An electrochemical device can include a cathode layer including an ionic conductor material and an electronic conductor material. The cathode layer can include a ratio of (Vi/Ve) of a volume of the ionic conductor material (Vi) to a volume of the electronic conductor material (Ve) of at least 1.3. In an embodiment, the cathode layer can include a median surface diffusion length (Ls) greater than 0.33 microns. In an embodiment, the cathode layer can include a cathode functional layer.
    Type: Grant
    Filed: June 14, 2019
    Date of Patent: November 15, 2022
    Assignee: SAINT-GOBAIN CERAMICS & PLASTICS, INC.
    Inventors: Sophie Marie Claire Poizeau, Juliette Lea Marylou Maria, John D. Pietras
  • Electrode comprising heavily-doped ceria
    Patent number: 10622628
    Abstract: An electrode can include a functional layer having an Ln2MO4 phase, where Ln is at least one lanthanide optionally doped with a metal and M is at least one 3d transition metal, and a heavily-doped ceria phase. In an embodiment, the ceria phase can be present in the functional layer in an amount of at least 40 vol % based on a total volume of the functional layer absent any porosity. An electrochemical device or a sensor device can include the electrode.
