Popis:	A novel polymer composite membrane PVDF-CsAl(SO 4 ) 2 ·12H 2 O with high conductivity within a wide temperature range (30-140 °C) is synthesized by composing PVDF and conductors CsAl(SO 4 ) 2 ·12H 2 O. 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(SO 4 ) 2 ·12H 2 O. The highest conductivity of 0.45×10 3 S·cm -1 was obtained at 140°C , The novel polymer composite membrane PVDF-CsAl(SO 4 ) 2 ·12H 2 O described here can be an attractive candidate as electrolyte in the low and medium fuel cell.
