The electrochemical behavior of a copper sulfide electrode (Cu,,,,S) in a sulfate bath containing Cu\*+ ions is studied by cyclic voltammetry and impedance spectroscopy techniques. Cyclic voltam- metry shows that several cathodic reductions occur at the copper sulfide electrode, one of which involve
