A Method for Oscillation-Free Dynamic IR Compensation
During Potentiostatic Electrolyses

Potentiostatic electrolysis is widely used to evaluate electrocatalyst stability but is often distorted by uncompensated solution resistance (IR drop).
The research groups of Prof. Dr. Soma Vesztergom and Prof. Dr. Peter Broekmann developed a novel method for 100% dynamic IR compensation using continuous resistance and current monitoring with adaptive setpoint control. The approach is demonstrated in nitrate-to-ammonia reduction at high current densities, enabling stable operation even under thermally induced resistance changes.
