Kim et prepared Nafion /zirconium sulphophenyl phosphate (ZSPP) composite membranes. ZSPP was precipitated by the reaction of Zr ion and m-sulphophenyl phosphonic acid (SPP) with a stoichiometric ratio P/Zr = 2. They found the conductivity of ZSPP to be about 10 S/cm, much higher than ZPL. The conductivity increased with the crystallinity of ZSPP. The increased conductivity may be related to more conduction channels through the interlayer of crystalline ZSPP. When 12.5 wt% ZSPP particles was incorporated in Nation , it showed quite high conductivity, 0.07 S/cm at 140 °C. [Pg.163]
