摘要： This invention concerns an electrolytic cell equipped with several bipolar electrodes which are connected in series during operation of the cell. Each of the bi-polar electrodes has a cathode side (K7, 8) and an anode side (A7, 8) between which an electrically conducting connection (11, 12) is established during operation. At least one bipolar electrode has a cathode side and an anode side which are displaceable towards one another. In particular, either the cathode side or the anode side can be separated and removed from the electrolyte.

摘要： This invention concerns a process in which gases or gas mixtures are reacted in the presence of an ion-conductive liquid in an electro-chemical cell. The cell has at least one anode (2) and at least one cathode (3) to which an external electrical constant potential is applied so that a direct current flows through the ion-conducting liquid. In the lower region of the cell a sump (4) of ion-conductive liquid is located into which the electrodes are partially immersed. At least 20 % of the entire surface of at least one of the electrodes is located outside the sump in an upper region through which gas flows. This upper region of the cell is sprayed or irrigated with the ion-conductive liquid and the electrode surface at least partially wet. During this wetting process, the gas flows across the electrode surface.
