(DE19715429-A1)      Electrochemical half cell (1) comprises an electrode chamber(2) containing an electrolyte (23), a gas chamber (6), and a gas diffusion electrode (7) as anode or cathode separating the gas chamber (6) and the electrode chamber (2). The novelty is that the electrode chamber (2) is divided into sections (2a, 2b, 2c) which are connected to each other to feed the electrolyte (23) in a cascade fashion over shafts (17, 18, 19).    USE -   For sodium dichromate electrolysis and for use in alkaline fuel cells.    (JP10287990-A)      Electrochemical half-cell (1) comprises an electrode chamber (2) for containing an electrolyte (23), a gas chamber (6), and a gas diffusion electrode (7) separating a gas chamber (6) and electrode chamber (2). The electrode chamber (2) is divided into sections (2a,2b,2c) which are connected to each other to pass the electrolyte (23) in cascade fashion over shafts (17,18,19).    USE -   In alkali halide electrolysis.    (ZA9803034-A)      Electrochemical half-cell (1) comprises an electrode chamber (2) for containing an electrolyte (23), a gas chamber (6), and a gas diffusion electrode (7) separating a gas chamber (6) and electrode chamber (2). The electrode chamber (2) is divided into sections (2a,2b,2c) which are connected to each other to pass the electrolyte (23) in cascade fashion over shafts (17,18,19).    USE -   In alkali halide electrolysis.
