Abstract
A water electrolysis system includes a water supply unit, a KOH tank, a water electrolysis apparatus, and a control device. The water supply unit and the KOH tank supply an aqueous solution containing hydroxide ions of a predetermined concentration to a cathode of the water electrolysis apparatus. The water electrolysis apparatus includes a solid polymer electrolyte membrane, and a water electrolysis cell having an anode and a cathode provided on both sides of the solid polymer electrolyte membrane. The control device changes the voltage to increase while restricting a supply amount of a KOH aqueous solution to the cathode when a concentration of the KOH aqueous solution is higher than a predetermined reference concentration on the basis of information on correspondence between a voltage and current between the anode and the cathode and the concentration of the KOH aqueous solution on the cathode.
