摘要： An active metal coating which lowers the hydrogen discharge overpotential at the cathode in the electrolysis of aqueous alkali metal halide solutions is deposited on the cathode tubes of a cathode can of an electrolysis cell without the removal of the tubes from the can. Plating solution and anodes of plating metal are placed inside a cathode can and the components are electrically connected so as to deposit an active coating onto the cathode tubes. The plating metal is preferably an alloy of nickel and zinc and the process involves the final step of leaching the zinc component of the alloy deposit from the plated cathode tubes to provide a porous, active nickel surface which results in a reduction of the hydrogen discharge overpotential for the electrolysis of alkali metal halides, particularly sodium chloride.

摘要： Electrolysis of impure solutions containing hardness impurities such as calcium and magnesium causes deposits to form on the cathodes of such an electrolysis cell which rapidly reduces the efficiency of the cell. The electrolysis cell of the instant invention contains a plurality of cathodes. The efficiency of such a cell is rejuvenated periodically by changing the polarity of less than the total number of cathodes in said cell so as to clean such cathodes while continuing normal operation of the cell by means of the remaining cathodes.
