Water electrolysis system, method of controlling water electrolysis system, and computer program

Abstract

To provide a technique of shortening a time necessary for raising the temperature of a water electrolysis device in a water electrolysis system.SOLUTION: The water electrolysis system comprises a water tank storing water to be supplied to a water electrolysis device, and a first heat exchanger disposed on a water supply flow path in which water to be supplied to the water electrolysis tank flows from the water tank, to exchange heat between a fluid including oxygen and water discharged from the anode side of the water electrolysis device and water to be supplied to the water electrolysis device.SELECTED DRAWING: Figure 1
