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.

Electrochromic layer-set

In an electrochromatic, transparent layer system comprising at least one electrochromatic layer (2), two electrodes (3, 5) separated by a hydrogen ion supplying layer which simultaneously is a hydrogen ion storing layer (4), there is located, seen in the direction of light incidence through the layer system, a further hydrogen ion conducting layer (6) (e.g. of SiO.sub.2) behind the electrode (5), behind which a further electrode (7) is arranged. The electrode (7) is capable of oxidizing hydrogen diffusing from within the system into hydrogen ions. For this purpose, a protective voltage is applied between electrode (5) and electrode (7) such that the third electrode (7) forms the positive pole.

Electrochromatic system with third electrode

Electrochromic mirrors hermetically sealed from the ambient environment and comprising at least one electrode, at least one electrochromic layer, a reflector, at least one ion-conducting layer, and at least one ion-supplying layer which simultaneously is an ion-storing layer and is not identical with the reflector, wherein the ion-conducting layer consists essentially of an ion-conducting inorganic solid.
