Description
Technical Field
[0001] The utility model belongs to the field of hydrogen production equipment, and in particular relates to a testing device for improving hydrogen production effect. Background Art
[0002] PEM water electrolysis refers to proton exchange membrane water electrolysis (Proton Exchange Membrane Electrolysis Water), also known as solid polymer water electrolysis. It is an electrochemical reaction process for producing hydrogen and oxygen, using a proton exchange membrane to decompose water into hydrogen and oxygen. In actual use, PEM water electrolysis hydrogen production equipment has the problem of low hydrogen production efficiency of the current device, that is, the low hydrogen production from a given electrical energy. This is because there is a lack of components to improve the hydrogen production effect. The lack of components to improve the hydrogen production effect will not only lead to the above problems, but also may cause the current device to have a slow hydrogen production rate. The hydrogen production rate refers to the amount of hydrogen produced per unit time. The low hydrogen production rate means that it takes longer to obtain the required amount of hydrogen. This may limit the practical applicability of PEM water electrolysis technology in applications that require a large amount of hydrogen, so it is necessary to propose a new structure to solve the above technical problems.

[0005] As a preferred embodiment, a proton exchange membrane is installed in the middle position inside the electrolytic tank, and two accommodating chambers are arranged inside the electrolytic tank through the proton exchange membrane. An anode is arranged inside the left accommodating chamber, and a cathode is arranged inside the right accommodating chamber. Titanium oxide is arranged on the outer surface of the anode, and platinum alloy and nickel catalyst are arranged on the outer surface of the anode. The anode and the cathode are electrically connected to a power supply through an electrical conductor, and the power supply is a DC power supply.
[0006] As a preferred embodiment, a heating plate is installed on the inner wall of the electrolytic tank in a ring shape, and the heating plate is electrically connected to a power supply, a temperature sensor, a relay and a single-chip computer through electric wires. The temperature sensor is located above the electric heating plate, and a light-emitting element is installed on the lower surface of the accommodating cavity on the left side. The light-emitting element includes a light-emitting chamber and a xenon lamp. A xenon lamp is installed inside the light-emitting chamber. After the anode and the cathode are powered on, the light-emitting element is started again so that it can provide an additional energy source. By adding the light-emitting element, light energy can be provided to stimulate the electrolysis reaction, thereby promoting the generation of hydrogen, thereby increasing the efficiency of hydrogen production. Since the titanium oxide on the outer surface of the anode is a common photocatalytic material with good photocatalytic properties, under the action of the light-emitting element, the titanium oxide can absorb light energy to generate electron- and positive-hole pairs, and promote the electrolysis of water through the reaction of photogenerated electrons on the surface and interface.

Because temperature has an important influence on the rate and effect of the electrolysis reaction, which will affect the hydrogen production effect, electrolyzed water is usually kept within an appropriate range (usually between 50-80 degrees Celsius) to achieve a good hydrogen production effect. Therefore, when the electrolysis water component supplies electrolyzed water to the electrolysis component, the heating element heats the electrolyzed water to increase the activity and kinetic energy of the electrolyzed water molecules, thereby accelerating the reaction rate. Within a certain temperature range (usually between 50-80 degrees Celsius), the reaction rate usually increases with increasing temperature. Therefore, heating the electrolyzed water can improve the efficiency of the electrolysis reaction and the hydrogen production rate.

[0011] After adopting the above technical scheme, the beneficial effect of the utility model is as follows: by setting an electrolysis component, the electrolysis component includes an electrolysis tank, a tank cover, an anode, a cathode, a proton exchange membrane, a heating plate, a temperature sensor and a light irradiation element, the lower surface of the electrolysis tank is provided with a light irradiation element, and the surface of the anode is provided with titanium oxide. After the anode and the cathode are powered on, the light irradiation element is started so that it can provide an additional energy source. By adding the light irradiation element, light energy can be provided to stimulate the electrolysis reaction, thereby promoting the generation of hydrogen, thereby increasing the efficiency of hydrogen production. Since the titanium oxide on the outer surface of the anode is a common photocatalytic material with good photocatalytic properties, under the action of the light irradiation element, the titanium oxide can absorb light energy to generate electron- and positive-hole pairs, and promote the electrolysis of water through the reaction of photogenerated electrons on the surface and interface. This photocatalytic property can improve the efficiency of the electrolysis reaction at the anode, thereby improving the hydrogen production effect.
[0012] By setting up an electrolytic water component, the electrolytic water component includes an electrolytic water storage tank, a water inlet pipe, a water outlet pipe, a pump, a pipeline 1, a pipeline 2 and a heating element. The upper surface of the electrolytic water storage tank is installed with a pump, the outlet of the pump is installed with a pipeline 1, the end of the pipeline 1 away from the pump is installed with a heating element, and the left surface of the heating element is installed with a pipeline 2. Because temperature has an important influence on the rate and effect of the electrolysis reaction, which will affect the hydrogen production effect, electrolytic water is usually kept within an appropriate range (usually between 50-80 degrees Celsius) to achieve a good hydrogen production effect. Therefore, when the electrolytic water component supplies electrolytic water to the electrolysis component, the heating element heats the electrolytic water to increase the activity and kinetic energy of the electrolytic water molecules, thereby accelerating the reaction rate. Within a certain temperature range (usually between 50-80 degrees Celsius), the reaction rate usually increases with increasing temperature.

A heating plate 140 is installed on the inner wall, and a gas recovery component is symmetrically installed on the left and right sides of the electrolysis component 100, and the gas recovery component includes a gas pipe 320, an air outlet pipe 310, an air valve 330 and a gas storage box 300. The air outlet pipe 310, the gas pipe 320 and the air valve 330 are installed on the upper surface of the gas storage box 300. The electrolysis water component 200 includes an electrolysis water storage tank 270, an inlet pipe 210, an outlet pipe 220, a pump 230, a pipeline 1 240, a pipeline 260 and a heating element 250. The outer surface of the electrolysis water storage tank 270 is installed with a water inlet pipe 210 and a water outlet pipe 220, and the upper surface of the electrolysis water storage tank 270 is installed with a pump 230.
[0022] See also Figure 1 , Figure 3 As the first embodiment of the utility model: a proton exchange membrane 170 is installed in the middle position of the electrolytic tank 110, and two accommodating chambers are arranged inside the electrolytic tank 110 through the proton exchange membrane 170, an anode 160 is arranged inside the left accommodating chamber, and a cathode 150 is arranged inside the right accommodating chamber, titanium oxide is arranged on the outer surface of the anode 160, and platinum alloy and nickel catalyst are arranged on the outer surface of the anode 160, and the anode 160 and the cathode 150 are electrically connected to the power supply 130 through an electric wire, and the power supply 130 is a DC power supply 130;
[0023] When the device is producing hydrogen by electrolysis, the user can start the xenon lamp inside the illumination chamber on the lower surface of the electrolytic tank 110, so that the xenon lamp emits light to illuminate the anode 160, and the surface of the anode 160 is provided with titanium oxide. At this time, the xenon lamp can provide an additional source of light energy. By adding the illumination element 180, light energy can be provided to stimulate the electrolysis reaction (when light is irradiated to the surface of the material, the energy of the light can stimulate the electrons in the material to jump from the valence band to the conduction band, forming charged electrons and positive holes. Under the action of light, the titanium oxide (TiO2) on the surface of the anode 160 in the electrolyzed water can absorb light energy and stimulate the photoelectric effect to generate charged electrons and positive holes. At this time, the excited electrons and positive holes undergo a photocatalytic reaction on the titanium oxide on the surface of the anode 160 , electrons can move from the conduction band to the titanium oxide surface, undergo a reduction reaction with water molecules to generate hydrogen ions (H+), and positive holes can move from the titanium oxide surface to the water molecules, undergo an oxidation reaction, and generate oxygen ions (OH-). These generated hydrogen ions and oxygen ions further participate in the electrolysis reaction of water electrolysis), thereby promoting the generation of hydrogen, thereby increasing the efficiency of hydrogen production. Since the titanium oxide on the outer surface of the anode 160 is a common photocatalytic material with good photocatalytic properties, under the action of the light irradiation element 180, the titanium oxide can absorb light energy to generate electron- and positive-hole pairs, and promote the electrolysis of water through the reaction of photogenerated electrons on the surface and interface. This photocatalytic property can improve the efficiency of the electrolysis reaction at the anode 160, thereby improving the hydrogen production effect.
[0024] See also Figure 1 , Figure 3 As the second embodiment of the utility model: the inner wall of the electrolytic tank 110 is annularly provided with a heating plate 140, the heating plate 140 is electrically connected to the power supply 130, the temperature sensor 141, the relay and the single-chip computer through electric wires, the temperature sensor 141 is located above the electric heating plate 140, and the lower surface of the left accommodating cavity is provided with a light illuminating member 180, the light illuminating member 180 includes a light illuminating chamber and a xenon lamp, and a xenon lamp is installed inside the light illuminating chamber;
[0025] A gas pipe 320 is symmetrically installed on the left edge and the right edge of the upper surface of the tank cover 120, respectively. The two gas pipes 320 are connected to the inside of the two accommodating chambers respectively. One end of the gas pipe 320 away from the tank cover 120 is connected to the upper surface of the gas storage box 300. A sealing ring is provided at the connection between the gas pipe 320, the tank cover 120 and the gas storage box 300.
[0026] Valves are installed on the outer surfaces of the gas pipe 320 and the gas outlet pipe 310;
[0027] A second pipe 260 is installed on the upper surface of the tank cover 120. The second pipe 260 is in a horizontal F-shaped structure. A heating element 250 is installed at one end of the second pipe 260 away from the tank cover 120. A pipe 1 240 is installed on the right surface of the heating element 250. One end of the pipe 1 240 away from the heating element 250 is connected to the outlet of the pump 230. The pump 230 is installed at the center of the upper surface of the electrolyzed water storage tank 270.
[0028] The inlet of the pump 230 is arranged at the bottom of the electrolyzed water storage tank 270 through a hose, an inlet pipe 210 is installed on the upper edge of the left surface of the electrolyzed water storage tank 270, and an outlet pipe 220 is installed on the lower edge of the right surface of the electrolyzed water storage tank 270. Sealing rings are arranged at the connection between the inlet pipe 210 and the outlet pipe 220 and the electrolyzed water storage tank 270, and valves are arranged on the outer surfaces of the inlet pipe 210 and the outlet pipe 220;
[0029] When in use, the user can start the pump 230 to make the pump 230 draw the electrolyzed water (PEM electrolyzed water) in the electrolyzed water storage tank 270 into the pipe 1 240, and then the pipe 1 240 enters the heating element 250. The heating element 250 is similar to a natural gas heating device. The electrolyzed water is then heated to about 50 to 80 degrees Celsius by the heating element 250, and then transferred to the inside of the pipe 2 260, and then enters the electrolytic cell from the pipe 2 260. At this time, the user can start the power supply 130, and then make the anode 160 and the cathode 150 work, and then electrolyze the electrolyzed water. When the anode 160 and the cathode 150 are working, the water molecules on the anode 160 are oxidized into oxygen (O2), and at the same time At the same time, oxygen from the side of the proton exchange membrane 170 passes through the membrane and enters the proton exchange membrane 170. These protons are conducted in the proton exchange membrane 170 and reach the cathode 150. On the cathode 150, the protons and electrons are combined again to generate hydrogen (H2). The hydrogen cannot return to the anode 160 side due to the property of the proton exchange membrane 170 that blocks electrons from passing through. Then, the generated hydrogen and oxygen enter the gas storage box 300 through the gas pipe 320 respectively. Then, the outlet pipe 310 on the upper surface of the gas storage box 300 can be opened to release the hydrogen or oxygen for subsequent operations. At the same time, the gas valve 330 on the upper surface of the gas storage box 300 can avoid the occurrence of dangerous situations caused by excessive gas storage.
[0030] Then, when the electrolysis tank 110 is electrolyzing, the user can set the temperature sensor 141 at a threshold value (50-80 degrees Celsius, the temperature sensor 141 is a prior art, and its model can be selected from existing product models on the market, and its working principle and structure are not described in detail here). When the temperature of the electrolyzed water inside the electrolysis tank 110 is lower than 50 degrees Celsius, the temperature sensor 141 sends a signal to start the heating plate 140 through the relay and the single-chip microcomputer to heat the electrolyzed water to above 50 degrees. When the electrolyzed water is higher than 80 degrees Celsius, the temperature sensor 141 sends a signal to turn off the heating plate 140 through the relay and the single-chip microcomputer, so that the electrolyzed water being electrolyzed can be heated, and the electrolyzed water group The heating element 250 inside the component 200 can also heat the electrolyzed water injected into the electrolysis tank 110, because the temperature has an important influence on the rate and effect of the electrolysis reaction, which will affect the hydrogen production effect. The electrolyzed water is usually kept within an appropriate range (usually between 50-80 degrees Celsius) to achieve a good hydrogen production effect. Therefore, when the electrolysis water component 200 supplies electrolyzed water to the electrolysis component 100, the heating element 250 heats the electrolyzed water to increase the activity and kinetic energy of the electrolyzed water molecules, thereby accelerating the reaction rate. Within a certain temperature range (usually between 50-80 degrees Celsius), the reaction rate usually increases with the increase of temperature. Therefore, heating the electrolyzed water can improve the efficiency of the electrolysis reaction and the hydrogen production rate.
