Nafion®/organosilica-SO3H membrane for proton exchange membrane fuel cell application |
| 초록 |
Sulfonated organosilica with hydrophilic-SO3H functional groups were used as the additive to reduce the methanol permeability of Nafion. The Nafion-sulfonated organosilica nano-composite membranes were prepared by mixing Nafion-dimethyl formamide solutions with sulfonated organosilica sol and casting to membranes. The methanol permeabilities for composite membrane are tested by gas chromatography according to the amount of the sulfonated silane. The cell performances of the Nafion-sulfonated organosilica membrane are evaluated and compared with the unsulfonated organosilica composite membrane and Nafion®117. |
