  • Metal suboxide and methods of preparing same
    Patent number: 9643158
    Abstract: A metal suboxide having a specific surface area of greater than or equal to about 1.5 m2/g is prepared by preparing a metal suboxide precursor, and heat-treating the metal suboxide precursor.
    Type: Grant
    Filed: December 17, 2014
    Date of Patent: May 9, 2017
    Assignee: SAMSUNG ELECTRONICS CO., LTD.
    Inventors: Dong Jin Ham, Bok Soon Kwon, Hyun-seok Kim, Joon Seon Jeong, Hyo Rang Kang, Jae Sung Lee, Sueng Hoon Han, Gang Hong Bae
  • Electrode catalyst and method of preparing electrode catalyst for fuel cell, and membrane electrode assembly and fuel cell including same
    Patent number: 9466843
    Abstract: An electrode catalyst for a fuel cell, a membrane electrode assembly including the electrode catalyst, and a fuel cell including the electrode catalyst. The electrode catalyst has excellent electrochemical activity compared to the currently commercially available Pt/C catalyst and is much cheaper than a catalyst using platinum. The electrode catalyst includes tungsten carbide having a specific surface area of about 10 to about 30 m2/g, and a metal catalyst comprising palladium (Pd) or palladium alloy.

  • ELECTRODE CATALYST, AND MEMBRANE ELECTRODE ASSEMBLY AND FUEL CELL INCLUDING THE ELECTRODE CATALYST
    Publication number: 20110053039
    Abstract: An electrode catalyst for a fuel cell having comparable electrochemical activity as a platinum electrode catalyst but is much cheaper than the platinum electrode catalyst has a structure in which palladium and at least one metal catalyst selected from the group consisting of nickel, gold, iron, and silver, and combinations thereof, are supported on a tungsten carbide and carbon mesoporous composite support. A membrane electrode assembly and a fuel cell including the electrode catalyst also has comparable electrochemical activity as a platinum electrode catalyst but is also much cheaper than the platinum electrode catalyst.
