Proton conductors which are thermally stable over a wide range and have good proton conductivities

摘要

Proton conductors comprising from 1 to 99% by weight of an acid and from 99 to 1% by weight of a nonaqueous amphoteric material which are thermally stable from -50° C. to 400° C. and have a proton conductivity of >=10-5 S/cm. The invention further relates to membranes comprising the proton conductors of the invention, processes for preparing the membranes and their use in electrochromic cells, secondary batteries and electrochromic displays.
