Abstract

The invention relates to an electrolyte arrangement for a cell having at least one anode (1) and at least one cathode (3) comprising at least three superposed layers (2.1, 2.2, 2.3), wherein the middle layer (2.2) comprises a porous electrically nonconductive structure, and wherein a layer of a polymer-based electrolyte (2.1, 2.3) is arranged on both opposite sides of the porous electrically nonconductive structure, wherein at least one of the superposed layers (2.1, 2.2, 2.3) contains a ceramic material, wherein the ceramic material of the middle layer (2.2) is selected from metal ion-conductive ceramic material, a ceramic material which does not conduct metal ions, and/or mixtures thereof, and the ceramic material of the polymer-based electrolyte layer(s) (2.1, 2.3) is a metal ion-conductive ceramic material.
