Hydrogen production system by electrolysis of water

Abstract

The application discloses a hydrogen production system by electrolysis of water, which comprises a power supply system, a central control system, an electrolysis system and a constant temperature control system. The constant temperature control system comprises a hot water supply tank, a hot water supply pump, a cold water supply tank, a cold water supply pump, a constant temperature water tank and a constant temperature water supply pump. The hot water supply tank stores first electrolyte water, and the temperature of the first electrolyte water is greater than a first temperature threshold. The hot water supply pump delivers the first electrolyte water to the constant temperature water tank. The cold water supply tank stores second electrolyte water, and the temperature of the second electrolyte water is less than the first temperature threshold. The cold water supply pump delivers the second electrolyte water to the constant temperature water tank, and third electrolyte water obtained by mixing the first electrolyte water and the second electrolyte water is stored in the constant temperature water tank. The constant temperature water supply pump delivers the third electrolyte water to the electrolysis system. The electrolysis system electrolyzes the third electrolyte water. In this way, the efficiency of hydrogen production by electrolysis of water can be improved.
