Abstract (en)
[origin: WO03064728A2] The invention relates to an electrochemical half-cell, in particular for the electrolysis of aqueous solutions of hydrogen chloride. Said cell comprises at least one gas chamber, which has a gas supply and a gas discharge, in addition to a liquid outlet and comprises a gas diffusion electrode, which lies on an electrically conductive current distributor and makes contact with the latter in a conductive manner. According to the invention, the current distributor has an exposed surface ranging between 5 and 65 %, preferably between 10 and 60 % and more specifically between 15 and 50 %, in relation to the total surface of said current distributor and a thickness of between 0.3 mm and 5 mm and preferably between 0.35 and 0.6 mm.
