Abstract
Abstract An electrochromic layer-set, operating with hydrogen, comprises a transparent substrate front face plate, at least two electrodes, at least one electrochromic layer, a hydrogen ion-storing layer, a hydrogen ion-conducting layer, a rear face in sealing relationship with the layer-set, directly following one of the two electrodes, there being a metallic layer between the rear face and the layer lying in front of the rear face (the electrode) or the rear face itself is formed by this metallic layer. The side of the metallic layer turned away from the substrate plate is optionally transformed into the oxide of the metal. For the application of such a metallic layer, the layer-set and a counter-electrode are immersed in an electrolyte containing the metal ions, with the electrode lying at the rear face of the layer-set being made the negative electrode.
