Abstract

A galvanic cell is described, having a metal oxide or metal sulfide electe and a metal electrode, and between them an electrolyte or separator, which is characterized by the fact that it contains as electrolyte a solid proton conductor, namely a zeolite having a proton-containing cation, which has in its crystal lattice passages a phase promoting proton transport.
