Abstract:A systematical study of current leakage in bipolar multi-cmpartment cell has been made. By using basic conceptions in electrochemistry and establishing equivalent circuit, a reasonable mathematical model of current leakage was developed. After simplified properly, basic principles of current leakage in bipolar electrolytic cells were found out. To verify the model, a series of experiments in electrolysis of aqueous copper sulphate were made. The effects of some elements on current leakage were observed and mathematical model was verified by Comparing the experimental results with the calculated ones according to the model.
