Embodiment 1

[0021] The invention provides an elastic cone-enhanced 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. Such as figure 1 As shown, the cathode includes a conductive substrate 1 , a hydrogen evolution cone 2 and an elastic cone 3 . The hydrogen evolution cone 2 and the elastic cone 3 are placed on the conductive substrate 1, and the hydrogen evolution cone 2 and the elastic cone 3 are arranged at intervals. The material of the conductive base 1 and the hydrogen evolution cone 2 is nickel. The material of the elastic pointed cone 3 is an elastic material.

[0022] In application, external force is applied to stir the electrolyte on the cathode side, causing the elect...

Embodiment 2

[0024] On the basis of Example 1, such as figure 2 As shown, the height of the elastic cone 3 is greater than the height of the hydrogen evolution cone 2. In this way, the elastic cone 3 is more susceptible to the action of the electrolyte, resulting in more swings, thereby generating stronger turbulent flow near the hydrogen evolution cone 2, and the hydrogen evolution cone 2 generates greater vibration, increasing the hydrogen The ability of the bubbles to desorb from the hydrogen evolution cone 2 improves the hydrogen production efficiency of the water electrolysis hydrogen production device.

Embodiment 3

[0026] On the basis of Example 1, such as image 3 As shown, the cathode also includes a carbon nanotube layer 4 , and the carbon nanotube layer 4 is placed on the hydrogen evolution cone 2 and the elastic cone 3 . In this way, the carbon nanotube layer 4, the hydrogen evolution cone 2, and the conductive substrate 1 together serve as a cathode, and both have the function of hydrogen evolution. Due to the smaller size of the carbon nanotubes, the hydrogen bubbles generated on the carbon nanotubes are smaller, which is more conducive to the desorption of the hydrogen bubbles. After the elastic cone 3 is introduced, under the action of the electrolyte, the elastic cone 3 swings, which also drives the carbon nanotubes to swing, and also improves the hydrogen bubble desorption capacity of the carbon nanotubes, thereby improving the efficiency of the electrolyzed water hydrogen production device. hydrogen production efficiency.

Abstract

The invention provides an elastic pointed-cone enhanced 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 comprises a conductive substrate, hydrogen-evolution pointed cones and an elastic pointed cone. During application of the device, an electrolyte on one side of the cathode is stirred by external force, so the electrolyte moves; the movement of the electrolyte drives the elastic pointed cone to swing, and the swing of the elastic pointed cone enables the pressure intensity of a fluid between the adjacent hydrogen-evolution pointed cones to fluctuate, so turbulent flow is generated; and under the action of the elastic pointed cone, the hydrogen-evolution pointed cone also vibrates. Due to the above two effects, force acting on hydrogen bubbles is increased, the desorption capacity of the hydrogen bubbles is enhanced, and therefore, the efficiency of hydrogen production through water electrolysis is improved. The device has the advantages of being convenient to use and high in 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 an elastic cone-enhanced strong hydrogen desorption electrolysis water hydrogen production device. Background technique [0002] In recent years, with the rapid development of the global economy and the rapid and continuous growth of global energy demand, research on new energy sources such as solar energy, tidal energy, wind energy, and geothermal energy has attracted more and more attention. Hydrogen energy has many advantages such as clean and pollution-free, high combustion efficiency, and transportability, and is an ideal green energy. Because the earth has a lot of water resources, hydrogen energy is also a potentially inexhaustible energy source. The development and utilization of hydrogen energy are highly valued by various countries. Electrolysis of water to produce hydrogen is the use of solar energy to irradiate the anode to photolyze water to produce hydr...
