摘要： According to an embodiment, a water electrolysis cell (20) generates hydrogen and oxygen by electrolyzing water supplied to an anode electrode (102) using a solid polymer electrolyte membrane (101) having the anode electrode (102) installed on one side and a cathode electrode (104) installed on the other side. The power source supplies a current and a voltage provided by a direct-current power source (30a) to between terminals of the water electrolysis cell (20). The controller (40) performs a first mode of control that, after stopping hydrogen generation, establishes a connection state that causes a discharge current in the opposite direction from a current direction inside the water electrolysis cell (20) during hydrogen generation, and controls a potential of the anode electrode (102) to a first potential while keeping a potential decrease speed at the anode electrode (102) during generation of the discharge current at a predetermined value.
