Abstract:
A glazing element, comprising:a first pane; a second pane spaced apart from said first pane and having a surface facing said first pane; an electrically conductive layer between said surface and said first pane, said electro-conductive layer being in contact with said surface for acting as an electrode; an electrochromic layer between said electrically conductive layer and said first pane, said electrochroic layer being in contact with said electrically conductive layer; an ion conducting layer between said electrochromic layer and said first pane, said ion conducting layer being in contact with said electrochromic layer; an electrocatalytic layer between said ion conducting layer and said first pane, said electrocatalytic layer being in contact with said ion conducting layer for acting as a counter electrode to provide an electrical connecting with said electrically conductive layer; a gas mixture between said electrocatalytic layer and said first pane for permitting operation of the glazing element at a reduced voltage; and a reducing gas component placed between said first and second panes that adsorb and dissociate at said electrocatalytic layer.
