Abstract
An electrochromic cell, connected to an electrical reference element equivalent to an element of the electrochromic cell of zero surface dimensions and zero electrolyte thickness, connected in series with a resistance R.sub.i identical to the ion resistance of the electrochromic cell (reduced to a same zero surface), a potential difference applied by a generator, in coloration and decoloration respectively, being such that the voltage at the terminals of the reference element is kept at a value below a coloration reference voltage or decoloration reference voltage respectively.
