Fast proton-conducting glasses were prepared via the hydrolysis of metal alkoxides. The glasses which were obtained by heating at 150 to 400C were chemically stable and exhibited conductivities of about 104S/cm at room temperature. These conductivities were higher, by about 4 orders of magnitude, than those of glasses which contained no P2O5. These high conductivities were attributed to fast proton transfer which was accelerated by molecular water, bonded with POH groups.
