摘要： An electrochemical half cell, particularly suitable for the production of chlorine from an aqueous solution of an alkaline chloride, comprises an electrode chamber (10) for electrolyte. Several gas pockets (20, 22) for gas are also provided. A gas diffusion electrode (36) separates the gas pockets (20, 22) from the electrode chamber (10). A connecting channel (26) is also provided, by means of which the two gas pockets (20, 22) are connected to each other. Gas in the lower gas pocket (20) can flow into the connecting channel (26) through an outlet opening (28). Said gas climbs therein in the direction of the arrow (46) and arrives in a second gas pocket (22), lying thereabove, through an inlet opening (30). According to the invention, a non-return element (40) is arranged in the connecting channel (26) to avoid ingress of electrolyte (42) into the gas pocket (22).

摘要： The present invention relates to an electrochemical cell suitable for a membrane electrolysis process, comprising (i) at least one anode compartment having a metal electrode, (ii) a cathode compartment having a gas diffusion electrode (iii) and an ion exchange membrane arranged between the anode compartment and the cathode compartment. The metal electrode that functions as an anode is capable of being dipped into an electrolyte during use and is provided with one or more orifices for the passage of gas formed during operation. The metal electrode can optionally be angled and/or curved, and the orifices preferably have guide structures that conduct the gas formed to a side of the metal electrode that faces away from the cathode. The present invention also relates to electrodes per se as well as methods for use of electrodes and electrochemical cells.
