Methods for cleaning cathodes (7) immersed in electrolytes, especially electrolytes containing ambient deuterium from D2O. The cathode is first driven with a positive voltage and current is drawn until oxygen evolution begins to dominate deuterium oxidation. Then a negative voltage is impressed on the cathode and several mA/cm<2> of current density are drawn for at least a day to reform the surface of the cathode (7). For palladium cathodes (7), the purity of the surface (8) is further improved by heating it in a vacuum furnace, cooling it in a deuterium atmosphere, etching the cooled surface in aqua regia, and rinsing it in D2O. |
