제목 Anhydrous proton conducting polymer electrolytes based on mesoporous silica material-PVP/poly(vinylphosphonic acid)-heterocycle composite membrane
초록 Triazole effectively promotes proton conductivity of materials under anhydrous conditions. The proton conduction in triazole was proposed as the transfer of protons between neighboring protonated and unprotonated guest molecules by Grotthus mechanism. Mesoporous silica SBA-15 was utilized to increase the proton conductivity through the formation of proton conductive pathway by reacting with acid groups in triazole. This approach could also prevent from leaching out of triazoles under fuel cell operation. The SBA-15/triazole/PVP-PVPA membranes showed the proton conductivity of 5.42 X 10-3 S/cm at 150 °C and low humidity (~10%).
