Problems solved by technology

[0002] Solar energy has been used as a clean fuel to replace coal, petroleum and other fossil fuels, but it has a disadvantage: it cannot be stored and transported like coal and petroleum, nor can it be used by people at night without the sun. If solar energy is used as A clean source of energy that powers the planet has to find a way to store the sun's energy
Although the existing method of hydrogen production can also produce gas, but because the distance between the two poles of the catalyst is relatively close (including nano-level and molecular level), the generated hydrogen atoms and oxygen atoms are very active, so the hydrogen and oxygen atoms are easy to undergo a chemical reaction. It is water, and a small amount of mixed gas is released, and a large amount of heat energy is generated at the same time. These heat energy will accelerate the reaction of hydrogen atoms and oxygen atoms to synthesize water, greatly reducing the benefits of hydrogen production, greatly reducing the amount of hydrogen and oxygen produced. Prospects for large-scale production are not optimistic
Moreover, due to the large distance between the two electrodes (generally at the centimeter level or decimeter level) in the existing method of hydrogen production, the physical distance from the ion electrophoresis generated by the positive and negative electrodes to the corresponding positive and negative electrodes is too large, and the time is too long, which is also The production of hydrogen and oxygen is not optimistic

Embodiment Construction

[0007] The present invention will be further described below in conjunction with the accompanying drawings.

[0008] The photovoltaic cell 2 is directly put into the electrolytic aqueous solution 1 of the traditional electrolytic hydrogen production device, and the two ends of the photovoltaic cell 2 will generate positive and negative voltages under the irradiation of light. The positive and negative voltages generated by the photovoltaic cell 2 in the electrolyzed aqueous solution will cause the aqueous solution to generate hydrogen and oxygen 3 . The traditional electrolytic hydrogen production device uses a catalyst (such as titanium oxide) to absorb light energy and provide electrons under the irradiation of light, so that hydrogen ions become hydrogen atoms, and at the same time take away the electrons of its hydroxide ions, so that hydroxide ions become hydrogen atoms. into oxygen atoms. Although hydrogen and oxygen are produced, due to the very close distance between ...

Abstract

The invention discloses a device for producing hydrogen fuel by decomposing water through solar energy. Specifically, a photovoltaic cell is directly placed into an electrolysis water solution of a traditional electrolytic hydrogen producing device, two ends of the photovoltaic cell can produce positive voltage and negative voltage under the irradiation of light, the positive voltage and the negative voltage which are produced by the photovoltaic cell in the electrolysis water solution can enable the water solution to produce hydrogen and oxygen, the distance between two poles of the photovoltaic cell is far larger than that between two poles of a catalyst, contact of hydrogen atoms and oxygen atoms which are produced in the water solution can be isolated effectively, and synthesis of water is prevented, so that the gas yield is greatly increased. Besides, compared with the traditional electrolytic device, the device has the advantages that the physical distance between a hydrogen producing area and an oxygen producing area is greatly shortened, the physical distance and the time for electrophoretic movement between the hydrogen producing area and the oxygen producing area are reduced, and the gas yield can also be increased.

Description

technical field [0001] The invention relates to a device for generating hydrogen fuel by using solar energy to decompose water, which is a device for directly putting photovoltaic cells into hydrolysis to produce hydrogen in a traditional electrolysis device. Background technique [0002] Solar energy has been used as a clean fuel to replace coal, petroleum and other fossil fuels, but it has a disadvantage: it cannot be stored and transported like coal and petroleum, nor can it be used by people at night without the sun. If solar energy is used as A clean source of energy that powers the planet has to find a way to store the sun's energy. After years of research, hydrogen has been found to provide a new solution for how to store solar energy. The current method of hydrogen production is to use a catalyst (such as titanium oxide) to absorb light energy and provide electrons under sunlight irradiation, so that hydrogen ions become hydrogen atoms, and at the same time get its ...
