DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example: Figure 1-Figure 7 As shown, the present invention provides a technical solution of a hydrogen supply system suitable for a fuel cell, comprising a gas supply device 1 and a controller 8, wherein the gas supply device 1 comprises a hydrogen production component 2, an oxygen storage tank 11, a hydrogen storage tank 12, a distribution component 3 and a plurality of power generation equipment 4, wherein the hydrogen production component 2 is respectively connected to the oxygen storage tank 11 and the hydrogen storage tank 12, wherein the oxygen storage tank 11 and the hydrogen storage tank 12 are respectively connected to the distribution component 3, and the distribution component 3 is respectively connected to the plurality of power generation equipment 4;

[0030] Therefore, when the device is in use, hydrogen can be prepared through the hydrogen production component 2 to be supplied to the power generation equipment 4 so that the power generation equipment 4 can generate electricity stably. When the hydrogen production component 2 of the device is in use, it can replenish the acidic medium in the hydrogen production component 2 according to the content of the generated oxygen and hydrogen, so that the electrolysis can be better carried out when hydrogen is produced by electrolysis. The oxygen and hydrogen generated by the hydrogen production component 2 can be recovered through the oxygen production tank and the hydrogen production tank 21, and the distribution component 3 can be fully distributed to the power generation equipment 4 according to the needs of the power generation equipment 4 and the current hydrogen content and oxygen content inside the power generation equipment 4, so that the power generation equipment 4 can generate sufficient electricity, thereby enabling the entire power station to generate stable electricity all the time. After the generated current is converted into direct current, the excess electricity can be supplied to the hydrogen production component 2, thereby achieving self-sufficiency.

[0031] like Figure 2 , Figure 4-Figure 6 As shown, in this embodiment, specifically, the hydrogen production component 2 includes a hydrogen production tank 21, and multiple groups of electrolytic components 5 are installed inside the hydrogen production tank 21. The electrolytic components 5 include multiple groups of limiting rings 51. A graphite rod 52 is installed between two groups of limiting rings 51. A joint 53 is installed at one end of the graphite rod 52. The graphite rod 52 is equidistantly installed between the two groups of limiting rings 51. The positive and negative poles of two adjacent groups of graphite rods 52 are staggered and arranged at the same end. The joints 53 on the same side of the limiting rings 51 are connected to each other through copper wires. A support block 54 is installed between the limiting rings 51. The support block 54 is installed between the limiting rings 51 through a support rod. A copper sheet 55 is installed between the two groups of support blocks 54. Multiple groups of limiting rods 14 are respectively installed between the multiple groups of copper sheets 55. Conductive columns are installed at both ends of the copper sheet 55 group. The conductive columns and copper wires are respectively connected to the controller 8.

[0032] When the hydrogen production component 2 of the device is in use, it cooperates with the electrolysis component 5 to electrolyze water. The principle of electrolysis to produce oxygen and hydrogen is mainly to use electrolytic ion exchange technology to carry out oxidation-reduction reaction on water ions in water, so that water is decomposed into oxygen and hydrogen, and then become active oxygen, and then converted from gas into oxygen, etc. When the electrolysis component 5 is in use, the device can supply power to the graphite rod 52, so that the graphite rod 52 electrolyzes the liquid in the hydrogen production tank 21, and the graphite can better adsorb water, and then can better electrolyze the water. At the same time, the multiple groups of copper sheets 55 between the limit rings 51 will also electrolyze the water, so that the positive electrode of the copper sheet 55 produces oxygen, and the negative electrode of the copper sheet 55 produces hydrogen. There are multiple groups of electrolysis components 5 in the hydrogen production tank 21, so that the electrolysis of water can be accelerated through the multiple groups of electrolysis components 5, and the production of hydrogen can be increased.

[0033] like Figure 1-Figure 2 As shown, in this embodiment, specifically, an adding component 6 is installed outside the hydrogen production tank 21, and the adding component 6 can add acidic substances to the hydrogen production component 2. The adding component 6 includes a liquid storage tank 61, and the liquid storage block is installed outside the hydrogen production tank 21. A detection component 7 is installed inside the hydrogen production tank 21, and the detection component 7 can detect the acidity of water in the hydrogen production tank 21. The detection component 7 cooperates with the adding component 6. An output port is provided at the bottom of the liquid storage tank 61, and the output port is closed by a valve. A guide pipe is connected between the output port and the hydrogen production tank 21;

[0034] Because the conductivity of water is low when it is simply electrolyzed, it is generally necessary to add a proper amount of electrolytes and acidic substances to the water so that the water can achieve the best electrolysis efficiency. When the device is in use, the electrolysis component 5 can quantitatively add appropriate electrolytes or acidic substances to the hydrogen production tank 21 so that the water in the hydrogen production tank 21 can reach the best electrolysis state. When used specifically, the liquid storage tank 61 can control the closure of the valve at the bottom to quantitatively inject a proper amount of sulfuric acid into the hydrogen production tank 21 so that the water electrolysis effect in the hydrogen production tank 21 reaches the best state. At the same time, the device can also detect water through the detection component 7, and then add a certain amount of sulfuric acid or other electrolytes according to the detection results obtained by the detection component 7. When the electrolyte or acidic substance or sulfuric acid in the hydrogen production tank 21.

[0035] like Figure 7 As shown, in this embodiment, specifically, the detection component 7 includes a shell 71, a glass electrode 72 is installed inside the shell 71, the glass electrode 72 and the shell 71 are hollow, a reference electrolyte 73 is arranged between the glass electrode 72 and the shell 71, and a reference electrode 74 is arranged between the glass electrode 72 and the shell 71, and the reference electrode 74 can cooperate with the reference electrolyte 73 to compare the detection results of the glass electrode 72;

[0036] When in use, the detection component 7 of the device can detect the water in the hydrogen production tank 21, detect its pH value, and then add a certain amount of electrolyte or acidic substance to the inside of the hydrogen production tank 21 according to the current pH value through the adding component 6. When in use, the glass electrode 72 is driven by the cylinder to contact the water in the hydrogen production tank 21, and then detect the current pH value. The pH value obtained will be compared with the values ​​obtained by the reference electrode 74 and the reference electrolyte 73 to obtain the final value. The subsequent adding component 6 can add electrolyte or acidic medium in a certain amount according to the above-obtained values, so that the liquid in the hydrogen production tank 21 can achieve the best electrolysis, so that the device can produce the most hydrogen when electrolyzing the liquid, so that the device can supply sufficient hydrogen energy to the power generation equipment 4, so that the power generation component can stably output electrical energy.

[0037] like Figure 1-Figure 2 As shown, in this embodiment, specifically, the detection component 7 is installed inside the hydrogen production tank 21 through a cylinder, the water in the hydrogen production tank 21 accounts for 80% to 85% of the total capacity of the hydrogen production tank 21, and the acidic medium in the hydrogen production tank 21 accounts for 0.3% to 0.4% of the water;

[0038] 80% to 85% of the total volume of the hydrogen production tank 21 is injected mainly to facilitate the circulation of gas so that the gas can have enough space to be discharged, and 0.3% to 0.4% of the total water acidic medium is added to the hydrogen production tank 21 to make the conductivity of the water reach the best state, so that the maximum amount of hydrogen and oxygen can be produced when the liquid in the hydrogen production tank 21 is electrolyzed.

[0039] like Figure 1 As shown, in this embodiment, specifically, an air pressure sensor is respectively arranged inside the oxygen storage tank 11 and the hydrogen storage tank 12, and an induction coil 13 is respectively installed outside the input pipe of the oxygen storage tank 11 and the hydrogen storage tank 12, and a limit rod 14 is installed inside the input pipe, and the limit rod 14 is limited between the input pipes by a support rod, and a limit groove is arranged on the limit rod 14, and an interference piece 141 and a spring 142 are installed inside the limit groove, one end of the spring 142 is connected to the limit groove, and the other end of the spring 142 is connected to the interference piece 141, and a magnetic piece is arranged at the end of the interference piece 141, and the spring 142 is installed at the end of the limit rod 14 away from the inlet of the input pipe;

[0040] When the device is in use, the gas inside the oxygen storage tank 11 and the hydrogen storage tank 12 can be detected in real time through the air pressure sensor, and the input gas can also be detected. When the gas flows through the input tank and enters the hydrogen storage tank 12, when the speed of the hydrogen reaches a certain speed, the impact force of the hydrogen will push the interference piece 141. When the impact force is greater than the pulling force of the spring 142, the impacted interference piece 141 will fall into the limit groove. When the interference piece 141 falls into the limit groove, the magnetic piece will break away from the magnetic field of the induction coil 13. Field range, and thus will not affect the induction coil 13, so it can be known that the current hydrogen production is in a relatively high state, and thus it is only necessary to maintain the current indicators, and when the impact force of the hydrogen cannot push the interference plate 141, or the impact force is less than the pulling force of the spring 142, the magnetic plate on the upper end of the interference plate 141 will be retained in the magnetic field range of the induction coil 13, and then the magnetic plate will affect the magnetic field of the induction coil 13, so that it can be known that the current hydrogen supply is insufficient, and then the controller 8 will make up for the missing part.

[0041] like Figure 3 As shown, in this embodiment, specifically, when the wind force of the supplied oxygen and hydrogen is greater than the pulling force of the spring 142: the interference sheet 141 will fall into the limiting groove, and the magnetic sheet will be out of the range of the induction coil 13;

[0042] When the wind force of the supplied oxygen and hydrogen is less than the pulling force of the spring 142, the interference sheet 141 will not fall into the limiting groove, and the magnetic sheet will interfere with the magnetic field of the induction coil 13.

[0043] When the device is in use, the gas inside the oxygen storage tank 11 and the hydrogen storage tank 12 can be detected in real time through the air pressure sensor, and the input gas can also be detected. When the gas flows through the input tank and enters the hydrogen storage tank 12, when the speed of the hydrogen reaches a certain speed, the impact force of the hydrogen will push the interference piece 141. When the impact force is greater than the pulling force of the spring 142, the impacted interference piece 141 will fall into the limit groove. When the interference piece 141 falls into the limit groove, the magnetic piece will leave the magnetic field range of the induction coil 13, and then It will not affect the induction coil 13, so it can be known that the current hydrogen production is in a relatively high state, and then it is only necessary to maintain the current indicators. When the impact force of the hydrogen cannot push the interference plate 141, or the impact force is less than the pulling force of the spring 142, the magnetic plate on the upper end of the interference plate 141 will be retained in the magnetic field range of the induction coil 13, and then the magnetic plate will affect the magnetic field of the induction coil 13, so that it can be known that the current hydrogen supply is insufficient, and then the controller 8 will make up for the missing part, and the same is true for the input pipe of the oxygen storage tank 11.

[0044] like Figure 1 As shown, in this embodiment, specifically, the distribution component 3 includes multiple groups of air supply pumps 31, the input ends of the multiple groups of air supply pumps 31 are respectively connected to the oxygen tank and the hydrogen tank, the output ends of the air supply pumps 31 are respectively connected to the power generation equipment 4, and the input ends of the air supply pumps 31 are installed with flow sensors;

[0045] Through the distribution component 3 of the device, the gas provided by each group of air supply pumps 31 can be detected in real time. When the gas supply of a group of air supply pumps 31 is insufficient, the output of the air supply pump 31 will be increased, thereby ensuring that each group of air supply pumps 31 can supply the same amount of hydrogen or oxygen. Then, when the power generation efficiency is reduced, the cause of the distribution component 3 can be eliminated first, so that the staff can check the device more quickly.

[0046] like Figure 1 As shown, in this embodiment, specifically, the input end of the power generation device 4 is connected to the oxygen storage tank 11 and the hydrogen storage tank 12 respectively, and the output end of the power generation device 4 is installed with an AC-DC converter 41, and the AC-DC converter 41 is connected to the controller 8;

[0047] Therefore, when the device is used, it can convert the electric energy generated by the power generation equipment 4 and convert AC power into DC power. The device is suitable for any type of hydrogen power generation, not only for fuel cells, but also for large-scale hydrogen-oxygen combined cycle power generation equipment 4.

[0048] like Figure 1 As shown, in this embodiment, specifically, the controller 8 is installed above the supporting platform, a distribution box is provided at the bottom of the controller 8, and a control panel is provided above the controller 8;

[0049] Therefore, when the device is in use, each device can be controlled through the controller 8, and the staff can operate the device through the control panel on the controller 8, and can also observe the current status of each device of the device and the total energy of the total output of electricity through the control panel.

[0050] Working principle: When the device is in use, hydrogen can be prepared through the hydrogen production component 2 to be supplied to the power generation equipment 4 so that the power generation equipment 4 can generate electricity stably. When the hydrogen production component 2 of the device is in use, it can replenish the acidic medium in the hydrogen production component 2 according to the content of the generated oxygen and hydrogen, so that the electrolysis can be better carried out when hydrogen is produced by electrolysis. The oxygen and hydrogen produced by the hydrogen production component 2 can be recovered through the oxygen production tank and the hydrogen production tank 21, and the distribution component 3 can be fully distributed to the power generation equipment 4 according to the needs of the power generation equipment 4 and the current hydrogen content and oxygen content inside the power generation equipment 4, so that the power generation equipment 4 can generate sufficient electricity, thereby enabling the entire power station to generate stable electricity all the time. After the generated current is converted into direct current, the excess electricity can be supplied to the hydrogen production component 2, thereby achieving self-sufficiency.

[0051] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
