A method for measuring ohmic resistance of solution layers at gas‐evolving electrodes was developed and tested. The method was applied to hydrogen and oxygen‐evolving electrodes, and the resistance of their adjacent solution layers (for a 9 mm electrode separator gap) causes a negligible IR drop. For 3 mm gaps at a current density of 300 mA/cm 2 , the IR drop of the solution layer increases to 25 mV. Contact resistances at the various electrode connections are shown to have a measurable contribution which increases with electrolysis time.
