Abstract

An electrochromic unit (1) having an electrochemical cell with at least two electrodes (3, 4) applied to a carrier, an electrolyte (2) located between the electrodes (3, 4) and an electrochromic material (7), such as an electrochromic polymer, applied to one of the electrodes (3), is characterized by a proton exchange membrane (2) as a solid electrolyte and carrier for the bilaterally applied electrodes (3, 4), the electrochromic material (7) being positioned on the side of the electrode (3) carrying it remote from the membrane (2).
