Abstract
It is shown experimentally that the gas produced on perforated plate e lectrodes in water electrolysis cells is generated in the gap between the electrode and the diaphragm. Under a minimum diameter of the perfo rations no gas evolution is observed; the bubbles block the perforatio ns. For hydrogen evolving electrodes, this minimum diameter is about 2 00 mum. The gap between the diaphragm and the electrode should be of t he same order of magnitude.
