  • Hydrogen gas detecting membrane
    Patent number: 8591828
    Abstract: An optical hydrogen gas detecting membrane is prepared by sequentially depositing a platinum oxide layer and a catalytic metal layer on a transparent substrate, such as quartz glass, by vapor deposition such as the sputtering method. Palladium or platinum is used as the catalytic metal layer.
    Type: Grant
    Filed: May 14, 2008
    Date of Patent: November 26, 2013
    Assignee: Japan Atomic Energy Agency
    Inventors: Shunya Yamamoto, Katsuyoshi Takano, Aichi Inouye, Masahito Yoshikawa
  • Hydrogen gas detecting material and the coating method
    Patent number: 8052898
    Abstract: A hydrogen gas detecting material, which changes in light absorption characteristics when exposed to an atmosphere containing hydrogen, and the coating method are characterized in that (1) the principal component of the hydrogen gas detecting material is tungsten oxide, (2) palladium is deposited on the surface of the tungsten oxide, (3) the tungsten oxide is coated on a substrate by a sputtering method involving a controlled oxygen pressure, and (4) the temperature of the substrate during coating with the tungsten oxide is room temperature (20° C.).
