Enhanced OH? Conductivity for Fuel Cells with Anion Exchange Membranes, Based on Modified Terpolymer Polyketone and Surface Functionalized Silica

Several modified terpolymer polyketones (MPK) with N-substituted pyrrole moieties in the main chain and quaternized amine side group were synthesized for use as anion exchange membranes fuel cells. The carried by SiO2 nanoparticles through surface functionalization (Si–N), which added to enhance their overall properties. On increasing amount of silica from 10% 60% wt/of MPK, there was an increase Si–N a corresponding threefold hydroxide conductivity membrane. MPK–SiN (60%) exhibited superior ionic 1.05 × 10?1 S.cm?1 at 120 °C, high mechanical stability, tensile strength 46 MPa 80 °C. In strongly alkaline conditions (1 M KOH, 216 h °C), maintained about 70% measured usual environment. Fuel cell performance °C showed peak power density 133 mW·cm?2, indicating that using surface-functionalized is simple effective way applications.
