- Abstract
- method. The FAS having hydrophobic functional group and silanol ligands is impregnated in Nafion. membrane to reduce methanolcrossover. The prepared FAS/Nafion inorganic-organic composite electrolyte membrane consist of the hydrophobic FAS-derivedsilicate nano-particles and Nafion. matrix showed decrease of methanol crossover and reduction of humidity dependence withoutlarge sacrifice of proton conductivity. The microstructural analysis of the composite membranes was performed using FESEM and FT-IR. And the effect of the incorporation of the hydrophobic FAS-derived silicate nano-particles into Nafion. membrane wasinvestigated via solvent uptake, membrane expansion rate, humidity dependency of proton conductivity and contact anglemeasurement.
