Problems solved by technology

[0004] However, since the electrolyte will gradually cool down as the downtime prolongs after a hydrogen production cycle ends, it is often necessary to reheat the electrolyte when the second hydrogen production cycle starts, resulting in a large waste of electrical energy. Moreover, the heating process of the electrolyte takes a long time, which affects the efficiency of hydrogen production.

Abstract

The hydrogen production electrolyte temperature control method and the hydrogen production system provided by the invention are applied to the technical field of hydrogen preparation. According to the method, after the current temperature of the electrolyte in the electrolytic bath is obtained, if the current temperature of the electrolyte is not within a preset temperature range, a heat preservation tank and a liquid supplementing device are controlled to adjust the electrolyte in the electrolytic bath; as the temperature of the electrolyte in the heat preservation tank is higher than that of the electrolyte in the liquid supplementing device, the average temperature of the electrolyte in the electrolytic bath can be increased through cooperation of the heat preservation tank and the liquid supplementing device, then the electric energy needed for heating the electrolyte to the preset temperature range is reduced, meanwhile, the heating time is shortened, and the hydrogen production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of hydrogen production, in particular to a method for controlling the temperature of an electrolyte for hydrogen production and a hydrogen production system. Background technique [0002] Hydrogen production by water electrolysis is the most commonly used hydrogen production method at present. The hydrogen production system by water electrolysis in the prior art basically includes hydrogen production power supply, electrolyzer, hydrogen storage tank and liquid replenishment device. Among them, the hydrogen production power supply and The electrolytic cell is connected, and the phase electrolytic cell provides the electric energy required for electrolysis of water. The electrolytic cell is respectively connected with the hydrogen storage tank and the rehydration device. The rehydration device is used to store and provide the electrolyte required for the electrolysis process. hydrogen. [0003] In actual use,...
