Abstract: A method has been developed for measuring IR-free potentials of electrodes of full-size electrolytic cells. It consists of interrupting the current on a small fraction of the working electrode only, called the probe electrode, and measuring the potential difference between probe electrode and reference electrode. The working and probe electrodes are kept at the same potential for most of the operation time by an external connection. The results of the measurements were compared to those obtained by the standard current interruption technique. The agreement was better than 15 mV for the cathode voltage and 10 mV for anode voltage at a current of 400 mA/cm2.
