The chlorine and caustic soda electrolytic cell with oxygen cathode has the advantages of low voltage across cell and less disturbance of gas to the neutral layer in the electrolyte because of no hydrogen being produced. Thus, when the parrellel arrangement of eletrodes in and opposite positions to each other is ad- opted, a better electrochemical properties can still be achieved even without using diaphragms and a structural model for the countercurrent flow of electrolyte.

The chlorine and caustic soda electrolytic cell with oxygen cathode has the advantages of low voltage across cell and less disturbance of gas to the neutral layer in the electrolyte because of no hydrogen being produced. Thus, when the parrellel arrangement of eletrodes in and opposite positions to each other is ad- opted, a better electrochemical properties can still be achieved even without using diaphragms and a structural model for the countercurrent flow of electrolyte. Under the given conditions of the cell structure, the concentration of salt solu- tion, as well as the current density, we varied the electroded distance, the elect- rolyte temperature and the speed of countercurrent flow and then measured the voltage and the current efficiency. It has been found that when the electrolyte contains 310 g/l NaCl, 3.5 g/l SO4, pH=7. and the total current is 3.5A (current density for cathode 10 A/dm2)the most appropriate parameters are: the electrodes distance B = 16mm. electrolyte temperature t = 50°-60°. the speed of countercurrent flow 40-54 ml/A.hr (11.4-15.4 ml/A.hr). In this way, the ob- tained concentration of alkali in solution is 118 g/l,the voltage across cell 2.06 Y and the current efficiency 93.0%.
