Description

Technical Field

[0002] With the acceleration of industrialization, energy consumption is increasing. The consumption of fossil fuels as the main energy source has brought serious environmental pollution and energy shortage problems. Hydrogen combustion is pollution-free and has high calorific value. It is an environmentally friendly clean energy with broad prospects for replacing fossil fuels. Water, as a renewable energy source with abundant content on the earth, is one of the important raw materials for the production of hydrogen and oxygen. The electrolysis of water to produce hydrogen and oxygen has the characteristics of efficient reduction power and clean hydrogen evolution, making it a promising method.

[0003] At present, a Chinese patent announcement with announcement number CN210771434U discloses a hydrogen storage device for solar hydrogen production, including a main body, a groove is opened on one side of the main body, air pressure valves are fixedly installed at both ends of the top of the groove, a controller is fixedly installed on one side of the groove, hydrogen storage tanks and oxygen storage tanks are fixedly installed at both ends of the top of the main body, and air valve heads are fixedly provided at the connection between the middle part of the bottom end of the hydrogen storage tank and the column and the connection between the middle part of the bottom end of the oxygen storage tank and the column. The hydrogen storage tank and the oxygen storage tank are fixed by the hydrogen storage device, and the gas storage work is automatically performed after the hydrogen pipe and the oxygen pipe of the solar hydrogen production device are connected. After the air pressure in the hydrogen storage tank and the oxygen storage tank reaches a certain level, the air pressure valve is automatically closed, and the hydrogen storage tank and the oxygen storage tank are lifted up after the gas is full, and the joints are automatically closed at the same time. The operation of taking out the hydrogen storage tank and the oxygen storage tank is simple, and the use is convenient and safe.
