  • Gas sensing element and method for manufacturing the same
    Patent number: 6849291
    Abstract: A gas sensing element has a solid electrolytic body, a reference gas side electrode provided on a surface of the solid electrolytic body so as to be exposed to a reference gas, and a measured gas side electrode provided on another surface of the solid electrolytic body so as to be exposed to a measured gas. A crystal face strength ratio of the measured gas side electrode according to X-ray diffraction is 0.7?{I(200)/I(111)} or 0.6?{I(220)/I(111)}.
    Type: Grant
    Filed: October 17, 2002
    Date of Patent: February 1, 2005
    Assignee: Denso Corporation
    Inventors: Gang E, Kiyomi Kobayashi, Yasumichi Hotta, Namitsugu Fujii
  • Gas sensor element and its production method
    Publication number: 20040007462
    Abstract: The present invention provides a gas sensor element and its production method, in which poisons are trapped in a porous protective layer to prevent them from reaching a measured gas side electrode, thereby making it possible to maintain a stable sensor output over a long period of time.
