Abstract
The invention relates to a system (1) comprising a glazing element (2) and a gas supply device (4), whereby the glazing element (2) has at least two substrates (18, 19), which enclose a space (3), and at least one gas of a defined composition located inside the space (3). A coating whose physical properties, in particular, optical and/or electrical properties, which can be altered according to the composition of the gas, is at least applied to one of the surfaces of a substrate (18, 19), said surfaces facing the space (3). The gas supply device (4) has at least one electrolysis device that has a working electrode (9), a counter electrode (10) and at least one electrolyte (17) for producing gas. The glazing element (2) and the gas supply device (4) are connected to one another whereby enabling the gas inside a closed circuit (6) to be guided between the glazing element (2) and the gas supply device (4). In addition, means for influencing the moisture content of the gas are placed inside the system.
