THEORETICAL-ANALYSIS AND EVALUATION OF THE OPERATING DATA OF BIPOLAR WATER ELECTROLYZER

The advanced design of the bipolar water electrolyser comprises the fo llowing aspects: electrocatalytic efficiency of the electrodes, corros ion resistance of the materials used, and optimization of process cond itions. They depend on the potential, the temperature and distribution Of mass in the electrolysis system. All three problem areas are discu ssed, and attention is first drawn to the importance of the precise de termination of the potential position of the electrodes in the electro lyser system. The mathematical methods for determining the necessary d ata. such as potential distribution, mass transport and temperature pr ofiles of the cell. were presented. The calculations were first carrie d out for a single cell but due to the periodicity of the properties t hey can be very simply transferred to systems with several individual cells.
