Abstract
Electrochemical, especially organo-electrochemical, reactions are carried out with improved current efficiency in a continuous-flow cell with the use of bipolar electrodes placed in a frame of non-conducting material, especially a polyolefin. Preferably, the electrically active part of the electrodes consists of glass-like carbon the cathode face of which is coated with a material reducing the hydrogen overvoltage, for example titanium carbide or tungsten carbide.
