The invention relates to a cathode half-shell of an electrolytic cell, comprising metallic cell-element components, comprising DEG a metallic support structure (2) welded to the rear wall of the cathode half shell (1), and at least one metallic spring element (4) arranged thereon in a plane-parallel manner, DEG an oxygen-consuming cathode arranged on the at least one metallic spring element and comprising a perforated metallic carrier (5) and a catalyst strip (6), mechanically pressed thereonto, consisting of PTFE and silver oxide, the silver oxide being reduced in the electrolysis operation to obtain silver and therefore producing a uniform connection, characterised in that it is highly conductive, between the components of the oxygen-consuming cathode and the at least one spring element, at least one of the metallic components being provided with an electrically conductive coating comprising at least two layers, DEG one first layer, which is applied directly to the cell-element materials, being selected from a group which contains Au, B-doped nickel, Ni-sulphide, and mixtures thereof, this first layer having a layer thickness of between 0.005 and 0.2 [mu]m, and DEG a second layer, applied to the first layer, consisting of silver and having a layer thickness of between 0.1 to 30 [mu]m.
