Abstract: The mechanism of oxygen reduction reaction was investigated by cyclic voltammetry and electrochemical impedance spectroscopy. Changes in high frequency resistance conduct us to distinguish the adsorbed species in different potentials.

Key words: silver, oxygen reduction, cyclic voltammetry, electrochemical impedance spectroscopy
