Abstract

Solid proton conductors are described, which are based on zeolites having oton-containing cations and having six-member and larger rings as secondary structural groups of the zeolitic structure, and in whose crystal lattice passages a phase is present which promotes proton transport. Their use as separator material and electrolyte for electrochemical cells is also described.
