A method of operating an electrochemical cell, the method comprising: introducing an aqueous solution comprising at least one of seawater, brackish water, and brine into an electrochemical cell between an anode and a cathode of the electrochemical cell; applying a current across the anode and the cathode at a voltage sufficient to generate a product compound from the aqueous solution in the electrochemical cell, wherein the current is applied in a pulsed waveform; 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 aqueous solution associated with hydrogen gas production, wherein the condition of the aqueous solution is selected from the group consisting of flow rate, dissolved oxygen concentration, dissolved hydrogen concentration, pH, ORP, and temperature of the aqueous solution being introduced into the electrochemical cell; and reversing polarity of the anode and the cathode in response to the voltage being outside of a range between 0.5 Volts and 4 Volts.
