Abstract

The invention relates to the technical field of resource utilization, in particular to a system for producing hydrogen from seawater. The system comprises a photoelectric conversion device, a primaryfiltering device, a secondary filtering device, a power supply device and an electrolysis device, wherein the primary filtering device is connected with the electrolysis device through the secondary filtering device, and the filtering precision of the secondary filtering device is higher than the filtering precision of the primary filtering device; and the photoelectric conversion device is connected with the electrolysis device through the power supply device. Since seawater resources and sunlight are rich, waste of fresh water resources is reduced since the seawater is used as a hydrogen production raw material, and the photoelectric conversion device is used for providing electric energy; and impurities in the seawater can be effectively removed and the water quality of the seawater during electrolysis is guaranteed through the two-stage filtering devices, and therefore, the service life of the electrolysis device can be prolonged.

Description

technical field [0001] The invention relates to the technical field of resource utilization, in particular to a seawater hydrogen production system. Background technique [0002] At present, the main hydrogen production processes include: hydrogen production from mineral fuels, hydrogen production from biomass, hydrogen production from chemical processes, and hydrogen production from water electrolysis. Hydrogen production by electrolysis of water is the most extensive and mature method for producing hydrogen. In the process of water electrolysis to produce hydrogen, a cathode and an anode are placed in the water. Under the action of electric current, the cathode forms hydrogen by reducing water, and the anode forms oxygen by oxidizing water. Hydrogen is produced in about twice the amount of oxygen. [0003] However, in the process of electrolyzing water, the amount of raw material water is very large, and if fresh water is used, it will cause a great waste of fresh water ...
