Abstract: A water electrolyzer includes an electrochemical cell including an anode and a cathode, an electrolyte solution, a heater, a voltage applicator, and a controller. The heater heats the electrolyte solution. The voltage applicator applies a voltage between the anode and the cathode. The electrochemical cell includes nickel. In startup of the water electrolyzer, the controller causes the heater to increase the temperature of the electrolyte solution by heating and causes the voltage applicator to start application of a voltage when the temperature of the electrolyte solution is less than a predetermined threshold value.
