ABSTRACT:
For charging an electrochromic layered package with hydrogen and for applying a backing to a layered package comprising a transparent substrate plate disposed on the front, at least two electrodes, where, of these two electrodes, the first electrode after this substrate plate (first electrode) is a transparent electrode, at least one electrochromic layer, a hydrogen-storing layer, a hydrogen ion-conducting layer and a backing which seals the layered package and directly follows the second of the two electrodes, an electrochromic layered system is initially, before application of the backing and after application of the second electrode, which is to be followed by the backing, electrolytically charged, in a first step, with hydrogen from a hydrogen ion-containing electrolyte solution and, in a second step, a metal layer is deposited reductively, preferably electrolytically, as a backing which provides sealing against H.sub.2 loss and H.sub.2 O exchange, onto the second electrode from a solution containing the pertinent metal as the ion, and the layered package is then completed.
