Preparation and Proton Conductivity of a Novel Polymer Composite Membrane PVDF- CsAl(SO4)2·12H2O
OPEN ACCESS
A novel polymer composite membrane PVDF-CsAl(SO4)2·12H2O with high conductivity within a wide temperature range (30- 140 °C) is synthesized by composing PVDF and conductors CsAl(SO4)2·12H2O. A sharp increase of the conductivity has been observed at around 90 °C, which was due to the release of the crystal water in the CsAl(SO4)2·12H2O. The highest conductivity of 0.45×10-3 S·cm-1 was obtained at 140°C , The novel polymer composite membrane PVDF-CsAl(SO4)2·12H2O described here can be an attractive candidate as electrolyte in the low and medium fuel cell.
