Abstract: A water electrolysis system produces hydrogen gas at a higher pressure than oxygen gas. A Peltier cooler is disposed between a gas-liquid separator and a back pressure valve in a hydrogen gas flow path, and cools and dehumidifies the hydrogen gas. A temperature sensor measures a temperature in the vicinity of the Peltier cooler, and outputs a temperature measurement value. A pressure sensor measures a pressure of the hydrogen gas between a cathode and the back pressure valve in the hydrogen gas flow path, and outputs a pressure measurement value. A control unit controls a cooling temperature by the Peltier cooler, in a manner so that the temperature measurement value becomes a target temperature that exceeds the freezing point of water corresponding to the pressure measurement value. At least a portion of the target temperature becomes lower as the pressure measurement value increases.

Abstract: In a water electrolysis system and a control method therefor, when a depressurizing process is performed, pressure reducing valves for high pressure reduce the pressure of a high pressure hydrogen. A first pressure detecting sensor detects, as a first pressure, a pressure of the high pressure hydrogen on a more upstream side than the pressure reducing valves for high pressure. A second pressure detecting sensor detects, as a second pressure, a pressure of the high pressure hydrogen on a more downstream side than a first pressure reducing valve of the pressure reducing valves for high pressure. Based on the first pressure or the second pressure, a controller controls a degree of opening of a depressurization control valve.
