| 제목 | Studies on the fabrication of zeolite/Nafion composite membranes with high proton selectivity using various zeolites and heteropoly acids for DMFCs |
| 초록 | Heteropoly acids-encaged zeolites/Nafion composite membranes were fabricated for direct methanol fuel cells(DMFCs) by solution-casting method. Heteropoly acids(HPAs) which have been proposed to enhance proton conductivity were incaged in zeolite by impregnation method and direct synthesis method. Incaged HPA, proton conductivity and methanol permeability of composite membranes were characterized by XRD, FT-IR, SEM, IM-6(for EIS) and refractive index detecter. |
