Polymer electrolyte membranes involving 1-Hexyl-3-methylimidazolium chloride, 1H-1,2,4-triazole and tetrazole functionalized silica nanoparticles in PVDF-HFP have been developed for high temperature fuel cells. The maximum proton conductivity reached to 1.1×102 S/cm with 10 wt% tetrazole functionalized silica nanoparticles at 130 °C. The proton conductivity shows an increase with the amount of the tetrazole functionalized silica particles and temperature. It has been demonstrated that the addition of tetrazole functionalized silica particles can be a very effective method in increasing the proton conductivity of polymer electrolytes. |
