Effect of Large Voltage Modulations on Electrodes Under Charge-Transfer Control

Source

The experimental test of the validity of a mathematical treatment of the effect of large a–c voltage modulations on the behavior of efectrodes under charge-transfer control was carried out for the case of the hydrogen evolution reaction. A frequency analysis of the resulting current showed that both d–c and a–c components of the faradaic current were in quantitative agreement with the predictions of the mathematical model. Deviations from the calculated values, which were observed in certain conditions (particularly at higher frequencies), were explained as the effect of the ohmic-drop error.
