Proton conductor with a temperature resistance in a wide range and good proton conductivities

摘要

The invention concerns proton conductors which contain between 1 and 99 wt % of an acid and between 99 and 1 wt % of a nonaqueous ampholyte, are resistant to temperatures of between -50 DEG C and 400 DEG C, and whose proton conduction is /= 10-5 S/cm. The invention further concerns membranes containing the proton conductors according to the invention, processes for preparing the membranes and their use in electrochemical cells, secondary batteries and electrochromic displays.
