Apparatus of the electrochemical-cell type with solid electrolyte, and method of manufacturing the same

Abstract

Abstract 1. A device of the electrochemical cell type having a solid state electrolyte of a cristal lattice structure consisting of a doped material such that holes are created in the lattice, the electrolyte being an exclusive ion conductor of a predetermined chemical nature and being in contact with two conducting electrodes, characterized in that the electrolyte comprises a first region (El1 ) having a first doping factor (DN ) and a second, superficial region (El2 ) having a second doping factor (DM ), this second region presenting a small thickness with respect to the first region and covering at least the surface of the first region under at least one of the electrodes (E2 ), and the second doping factor (DM ) being higher than the first one (DN ) in order to increase the number of holes created in the lattice and to increase the ionic exchange currents at the interface between the solid state electrolyte and the medium outside that solid state electrolyte.
