Pulsed power supply for sustainable redox agent supply for hydrogen abatement during electrochemical hypochlorite generation

A method of operating an electrochemical cell, the method comprising steps of:

• introducing a chloride-containing aqueous solution into an electrochemical cell between an anode and a cathode of the electrochemical cell;
• applying a current across the anode and the cathode at less than 1.6 volts to generate a hypochlorite-containing product compound from the chloride-containing aqueous solution in the electrochemical cell;
• monitoring at least one parameter selected from the group consisting of the voltage, a concentration of dissolved hydrogen in a product solution generated in the electrochemical cell, and a condition of the chloride-containing aqueous solution associated with hydrogen gas production, the condition of the chloride-containing aqueous solution being selected from the group consisting of flow rate, dissolved oxygen concentration, dissolved hydrogen concentration, pH, ORP, and temperature of the chloride-containing aqueous solution being introduced into the electrochemical cell;
• and
• applying the current across the anode and the cathode in a pulsed waveform responsive to the at least one parameter being outside of a predetermined range, wherein pulsed power is applied in a pulse of less than 500 seconds, in a cathodic potential of less than 1.6 volts and each parameter of the condition is controlled to maintain the voltage.
