Abstract

Additional energy losses in water electrolysis are caused by the evolution of gas bubbles. The main aim of this investigation is to obtain dimensionless correlations for the ohmic resistance between the working electrode and the diaphragm in the presence of gas bubbles and for the average radius of the bubbles at the outlet of the electrolysis cell. The resistance and the average bubble radius have been determined in dependence of KOH concentration, temperature, pressure, gas to liquid volumetric ratio at the outlet of the cell, nature of the nickel electrode surface, electrode geometry and distance between working electrode and diaphragm. From the experimental results a following dimensionless correlation for the reduced resistance between the working electrode and the diaphragm has been deduced.
