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

The advanced design of the bipolar water electrolyser comprises the following aspects: electrocatalytic efficiency of the electrodes, corrosion resistance of the materials used, and optimization of process conditions. They depend on the potential, the temperature and distribution Of mass in the electrolysis system. All three problem areas are discussed, and attention is first drawn to the importance of the precise determination of the potential position of the electrodes in the electrolyser system. The mathematical methods for determining the necessary data. such as potential distribution, mass transport and temperature profiles of the cell. were presented. The calculations were first carried out for a single cell but due to the periodicity of the properties they can be very simply transferred to systems with several individual cells.
