Abstract A new type of electrochemical cell with two reference electrodes was designed to meet the requirement of solution resistance correction in the measurement of stationary polarization curves. The distance from the reference electrodes to working electrode should be accurately adjusted. The effect of solution resistance was eliminated by calculation from the potential data measured with these two reference electrodes. The results of simulation circuit and some real systems showed that this experimental technique was practical for the study of corrosion electrochemistry.

Key words: Polarization curve Solution resistance Reference electrodes
