Embodiment 1

[0018] The invention provides a strong hydrogen desorption electrolysis water hydrogen production device, which comprises an electrolytic cell, an anode, a cathode and a diaphragm. The anode, cathode, and diaphragm are placed in the electrolytic cell. A separator is placed between the anode and cathode. The electrode material of the anode is platinum, graphite, graphene or titanium dioxide. The cathode is the carbon nanotube layer 1 . like figure 1 As shown, the carbon nanotube layer 1 is fixed on the cantilever beam 2, and the cantilever beam 2 is a semiconductor material or diamond. The cantilever beam 2 is fixed on the base 3, and the base 3 is connected with a vibration source, and the vibration source drives the base 3 to vibrate.

[0019] When in use, in the electrolyte, the anode generates electrons after absorbing light, and the electrons flow to the cathode through the external circuit, and the hydrogen ions in the water receive electrons at the cathode to generat...

Embodiment 2

[0023] On the basis of Example 1, a conductive hoop layer is provided outside the carbon nanotube layer 1 . The conductive mesh hoop layer is activated carbon fiber. In this way, on the one hand, the conductive mesh hoop layer prevents the carbon nanotube layer 1 from falling off; on the other hand, the conductive mesh hoop layer is activated carbon fiber, and the activated carbon fiber can also be used as a cathode to generate hydrogen on the activated carbon fiber.

Embodiment 3

[0025] On the basis of Example 1, such as figure 2 As shown, it also includes a tapered layer 4 , the tapered layer 4 is fixed on the cantilever beam 2 , and the carbon nanotube layer 1 is fixed on the tapered layer 4 . The tapered layer 4 comprises pointed cones. The material of the tapered layer 4 is nickel. The tapered layer 4 has more surface area relative to the planar structure. During application, the volume of hydrogen gas bubbles formed on the surface of the tapered layer 4 is smaller, and the hydrogen gas bubbles are easier to detach from the carbon nanotube layer 1; in addition, the present invention fixes the tapered layer 4 and the carbon nanotube layer 1 on the cantilever beam 2 Above all, the vibration of the cantilever beam 2 makes it easier for the hydrogen bubbles in this embodiment to detach from the carbon nanotubes, improving the hydrogen desorption capacity, thereby improving the hydrogen production efficiency of the device.

Abstract

The invention provides a device for hydrogen production through electrolysis of water and with strong hydrogen desorption performance. The device comprises an electrolytic cell, an anode, a cathode and a diaphragm, wherein the cathode is a carbon nanotube layer, and the carbon nanotube layer is fixed on a cantilever beam. In use, the carbon nanotube layer vibrates under the driving of the cantilever beam, and the hydrogen desorption capacity of the carbon nanotube layer is enhanced, so the hydrogen production efficiency of water electrolysis is improved. The device has the advantages of simplestructure, convenience in use and high hydrogen production efficiency, and has important application value in the field of hydrogen production through electrolysis of water.

Description

technical field [0001] The invention relates to the technical field of hydrogen production, in particular to a strong hydrogen desorption electrolysis water hydrogen production device. Background technique [0002] In recent years, with the development of the global economy, the global energy demand continues to grow, and the research on finding new energy sources has attracted more and more attention. Hydrogen energy has many advantages such as cleanness, high efficiency, and transportability. It is an ideal pollution-free green energy source and a potentially inexhaustible energy source. The development and utilization of hydrogen energy are highly valued by various countries. Hydrogen production by electrolysis of water is the use of solar energy to photolyze water to produce hydrogen, which is an important way to obtain hydrogen energy. However, due to the slow desorption rate of hydrogen from the cathode surface, the efficiency of conventional photo-splitting of water ...
