  • Ion conductive composite membrane using inorganic conductor
    Patent number: 7981568
    Abstract: An ion-conductive composite membrane and a method of manufacturing the same, the membrane including phosphate platelets, a silicon compound, and a Keggin-type oxometalate and/or Keggin-type heteropoly acid, wherein the phosphate platelets are three-dimensionally connected to each other via the silicon compound. An electrolyte membrane having an ion-conductive inorganic membrane or an ion-conductive organic/inorganic composite membrane effectively prevents crossover of liquid fuel without the reduction of ion conductivity in a liquid fuel cell, thereby allowing for the production of fuel cells having excellent performance.
    Type: Grant
    Filed: February 4, 2011
    Date of Patent: July 19, 2011
    Assignee: Samsung SDI Co., Ltd.
    Inventors: Hyuk Chang, Hae-kyoung Kim, Hasuck Kim, Jin-Kyu Lee, Sangook Park, Shin Woo Ha
