제목 | Fabrication of Nanocomposite Membranes Based on Graft Polymerization and Sol-gel Process for Polymer Electrolyte Membrane Fuel Cells |
초록 | Proton conducting nanocomposite membranes consisting of poly(vinylidene fluoride-co-chlorotrifluoroethylene)-graft-poly(styrene sulfonic acid), i.e., P(VDF-co-CTFE)-g-PSSA graft copolymer and sulfonated silica and were prepared using a sol-gel reaction and subsequent oxidation of a silica precursor, i.e., (3-mercaptopropyl) trimethoxysilane (MPTMS). As a result, both proton conductivity (0.12 S/cm at 25 oC) and single cell performance (1.0 W/cm2 at 75 oC) were maximal at 5 wt% MPTMS. |
