A new class of glass composite membranes of various compositions was prepared via a sol-gel technique. The membranes, consisting of (phophotungsticacid/phosphomolybdicacid) PWA/PMA-P2O5-SiO2 mixed with either ZrO2 or TiO2 displayed varying properties depending on their composition and mode of fabrication. The structure and property of the obtained glass ceramic composite membranes were investigated by FTIR, TG/DTA and textural analysis. The results included good mechanical, textural and thermal properties and the materials were deemed to be suitable electrolytes for fuel cell applications.
