TECHNICAL FIELD

[0001] The present application relates to the technical field of electrolytic water, in particular to an oxygen-heat-electricity-hydrogen comprehensive energy supply backpack for high-cold and hypoxic areas. BACKGROUND

[0002] In high-altitude areas, due to low air pressure and thin oxygen, people often face health risks such as hypoxia. Especially for residents, explorers or special operation personnel who are in these environments for a long time, oxygen supply becomes a critical need. However, the existing oxygen supply methods, such as carrying oxygen cylinders or using portable oxygen machines, usually have problems such as inconvenience to carry, heavy weight, large space occupation, difficulty in oxygen storage and replenishment, etc. In addition, these devices often cannot provide other energy such as heat and electricity at the same time, so that in cold high-altitude environments, personnel not only face the problem of hypoxia, but also often need to cope with the physiological pressure brought by cold. Traditional heating devices, such as fuel heaters and electric heating devices, can provide short-term heat support, but they usually have large volume, rely on limited fuel, and it is inconvenient to replenish fuel, resulting in poor endurance of the heating device and complex operation, making it difficult to achieve long-term stable heat supply.

[0003] The oxygen supply technology devices on the market have the problems of single supply mode, low hydrogen utilization rate, and lack of heating and power supply components. Therefore, how to improve the integration of oxygen supply technology devices is a technical problem that needs to be solved today. SUMMARY

[0006] The oxygen-heat-electricity-hydrogen comprehensive energy supply backpack for high-cold and hypoxic areas provided by the embodiment of the application integrates water electrolysis hydrogen and oxygen production, fuel cell power generation and heating, efficient heat supply of the heat supply layer, and preparation of hydrogen-rich water in a single backpack system, improves the integration of the energy supply backpack, improves the richness of the functions of traditional outdoor equipment, reduces equipment redundancy, generates hydrogen and oxygen by consuming water through an electrolysis assembly, directly supplies hydrogen to a fuel cell for power generation, realizes sustainable supply of oxygen, heat energy, electricity, and hydrogen-rich water, avoids the problem of scattered energy supply, and simultaneously, the heat supply unit can supply heat according to needs, thereby improving the oxygen and heat supply capacity in a high-altitude, low-oxygen, and high-cold environment.

[0007] Optionally, a shock-absorbing partition is arranged in the backpack body, and the shock-absorbing partition is arranged in the backpack body and defines the first chamber, the second chamber, and the third chamber.

[0008] In the above scheme, the shock-absorbing partition can absorb impact force through its own deformation to provide buffer protection for the core components in the chamber, avoid line loosening, part falling off, or shell damage caused by vibration, and prolong the service life of the equipment.

[0009] Optionally, the backpack body is made of a lightweight composite material, the outer side of the backpack body is coated with a waterproof thermal insulation material, and the shock-absorbing partition has at least one of a honeycomb structure, a foam filling structure, and a micro air bag structure.

[0010] In the above scheme, the waterproof material coated on the outer side can block the penetration of liquid such as rainwater, dew, and splashed water, avoid the circuit of the internal electrolysis assembly from being short-circuited due to moisture, reduce the probability of failure of the drying device of the fuel cell due to water ingress, on the other hand, the thermal insulation material can reduce the heat exchange between the inside and outside of the backpack, effectively recover the waste heat of each component during work, help to reduce the waste of heat in a high-cold and low-pressure environment, help to continuously supply heat to the user in a low-temperature environment, reduce the probability of electrolyte (water) freezing and fuel cell electrode activity reduction of the electrolysis assembly due to excessively low temperature, maintain the normal working temperature of the equipment, improve the utilization efficiency of internal heat, and the shock-absorbing partition can absorb high-frequency vibration and external impact to protect each component inside the backpack body.

[0011] Optionally, the electrolysis assembly includes a water electrolysis bottle, a gas-liquid separator, and an electrolysis cell, the top of the separator is provided with a first opening, a second opening, and a third opening, the bottom of the separator is provided with a fourth opening, the fourth opening is in communication with the water inlet of the electrolysis cell, the water-hydrogen mixed outlet of the electrolysis cell is in communication with the second opening, the third opening is in communication with the hydrogen outlet of the electrolysis assembly, and the oxygen outlet of the electrolysis cell is in communication with the oxygen outlet.

[0012] In the above scheme, when the electrolytic cell is working, electrolysis of water produces hydrogen, oxygen and unreacted water to form a "water-hydrogen mixture". The gas-liquid separator can effectively remove the liquid water in the hydrogen gas, avoid the water entering the fuel cell in the second chamber, reduce the probability of electrode short circuit, improve the stability of power generation, the oxygen outlet of the electrolytic cell is directly connected with the oxygen outlet, reducing the mixing probability with hydrogen and water, ensuring the purity of oxygen, the fourth opening at the bottom of the liquid separator is connected with the water inlet of the electrolytic cell, which means that the unreacted water settled in the separator can flow back to the electrolytic cell to participate in electrolysis again, reducing water waste and helping to extend the use time of single water supply and reduce the frequency of replenishment.

[0013] Optionally, a first pipeline is arranged between the water-hydrogen mixture outlet of the electrolytic cell and the second opening, and the first pipeline is provided with a first circulating pump.

[0014] In the above scheme, the first circulating pump provides additional power for the mixture by active pressurization, ensuring that it quickly and stably enters the gas-liquid separator through the first pipeline, which helps to improve the bubble detachment efficiency and ensure rapid bubble detachment. The problem of slow bubble detachment and low hydrogen production efficiency in low-pressure environments can be solved. It can be understood that the forced transportation of the circulating pump can speed up the circulation speed of the unreacted water from the electrolytic cell to the separator and then back to the electrolytic cell, reducing the probability of slow flow or even stagnation of the mixture due to the increase in water viscosity in high-altitude, low-temperature or low-pressure environments.

[0015] Optionally, the electrolytic water bottle, the gas-liquid separator and the electrolytic cell are arranged in the first chamber from top to bottom.

[0016] In the above scheme, the electrolytic water bottle is located at the top as a new water source, so that the water flows naturally downward into the gas-liquid separator under the action of gravity, without the need for additional power to supplement the water in the circulation system, reducing the energy consumption of the system. When the water-hydrogen mixture enters the gas-liquid separator from the electrolytic cell located below, the separation effect can be enhanced by the difference in gravity during the upward process of the mixture: the liquid is more likely to settle at the bottom under the action of gravity, and the hydrogen gas with smaller density is more likely to float to the top and be discharged, reducing the dependence on the circulating pump.

[0017] Optionally, the oxygen outlet of the electrolytic cell is connected to a quick connector provided on the main body of the backpack through a pipeline, and the quick connector is used to connect a quick connector of an external oxygen inhalation device.

[0018] In the above scheme, the quick connector can be connected without tools, and can quickly supply oxygen to oxygen cylinders, masks and other devices, improving the operation efficiency.

[0019] Optionally, a liquid level sensor is arranged in the gas-liquid separator, and the liquid level sensor is connected to the control circuit board through a signal line.

[0020] In the above scheme, the liquid level sensor can detect the liquid level in the separator in real time, facilitate monitoring the state of the material in the gas-liquid separator, help monitor whether the liquid level is in the optimal interval, facilitate ensuring continuous and efficient gas-liquid separation, facilitate observing the liquid surface, and help prevent liquid from splashing out and backflowing to the electrolytic water bottle.

[0021] Optionally, the hydrogen assembly further comprises a drinking water bottle, a drying device, a fuel cell and a waste liquid bottle, the bottom of the drinking water bottle is provided with a nano gas disc, the air inlet of the drying device is in communication with the hydrogen outlet, the exhaust port of the drying device is in communication with the nano gas disc, the hydrogen inlet of the fuel cell is in communication with the exhaust port of the drying device, the oxygen inlet of the fuel cell is in communication with the outside, and the water outlet of the fuel cell is in communication with the waste liquid bottle.

[0022] In the above scheme, the drying device can dehydrate the hydrogen gas from the hydrogen outlet, avoiding water entering the fuel cell, and a part of the hydrogen gas passes through the nano gas disc to form hydrogen-rich water in the drinking water bottle, further improving the hydrogen utilization rate.

[0023] Optionally, the fuel cell is provided with a sixth opening, and the sixth opening is connected with the hydrogen inlet of the fuel cell through a one-way valve to transport the unreacted hydrogen gas of the fuel cell to the hydrogen inlet of the fuel cell.

[0024] In the above scheme, the sixth opening can return the hydrogen gas not participating in the electrochemical reaction to the hydrogen inlet through the one-way valve, so that the hydrogen gas reenters the fuel cell to participate in the reaction, which helps to improve the energy utilization rate, reduce energy waste, recover hydrogen gas in the low-load operation or start-up stage, and improve the power generation per unit of hydrogen gas without increasing the electrolysis load, thereby prolonging the endurance time.

[0025] Optionally, the heat supply layer comprises an electric heating device and a heat-conducting waterproof layer, the heat-conducting waterproof layer covers the electric heating device, and the electric heating device is at least one of a graphene heating sheet, a polyimide heating film and a flexible carbon nanotube heating film.

[0026] In the above scheme, the high thermal conductivity of the heat-conducting waterproof layer can reduce thermal resistance, more efficiently transfer heat, reduce energy waste, and prevent water vapor generated during equipment operation from invading the inside of the heating device, thereby reducing the probability of equipment short circuit.

[0027] Optionally, the backpack body further comprises a storage cavity for storage, the first cavity and the second cavity are arranged on the left and right sides of the storage cavity, and the third cavity is arranged on the lower side of the storage cavity.

[0028] In the above scheme, the storage cavity serves as the core storage area, which can facilitate the storage of articles. The first cavity is used to store the electrolysis assembly, and the second cavity is used to store the hydrogen assembly. The separation of the two cavities can avoid the entanglement of the equipment pipelines. The third cavity is located at the lower part to store the power supply assembly, which is relatively heavy. The use of gravity can stabilize the center of gravity and reduce the displacement of articles when the backpack shakes. BRIEF DESCRIPTION OF DRAWINGS

[0038] In high-altitude areas, the lower air pressure and thin oxygen often cause humans to face health risks such as hypoxia. Especially for residents, explorers or special operation personnel who are in these environments for a long time, oxygen supply becomes a critical need. However, the existing oxygen supply methods, such as carrying oxygen cylinders or using portable oxygen machines, usually have problems such as inconvenience to carry, heavy weight, large space occupation, difficulty in oxygen storage and replenishment, etc. In addition, these devices often cannot provide other energy such as thermal energy and electric energy at the same time, so that in cold high-altitude environments, personnel not only face the problem of hypoxia, but also often need to cope with the physiological pressure brought by cold. Traditional heating devices, such as fuel heaters and electric heating devices, can provide short-term heat support, but they are usually bulky, dependent on limited fuel, and it is inconvenient to replenish fuel, resulting in poor endurance of the heating device and complex operation, making it difficult to achieve long-term stable heat supply.

[0039] The existing oxygen supply technology devices on the market have the problems of single supply mode, low hydrogen utilization rate, lack of heating and power supply components, etc. For example, in Chinese patent CN222092275U, molecular sieve technology is used to compress air to achieve portable oxygen supply, but this technology has low oxygen purity, high energy consumption, and cannot provide hydrogen energy, heat energy and electric energy; In Chinese patent CN221964250U, water electrolysis technology is used to realize oxygen inhalation and hydrogen drinking integration, but hydrogen is only used to prepare hydrogen-rich water or directly discharged, and when sufficient oxygen is generated, a large amount of hydrogen is wasted; In Chinese patent CN211771583U, a filtration system is used to filter electrolytic water to generate hydrogen and oxygen, ensuring gas purity, but in actual use, users have different needs for hydrogen and oxygen, and the patent does not make full use of hydrogen, and the device uses the inner wall of the backpack body as the chamber boundary, which has high maintenance cost. In Chinese patent CN111264999B, a separate space is used to accommodate an oxygen inhalation bag for oxygen supply, which has limited capacity and cannot provide energy for a long time; Therefore, there is an urgent need for a highly integrated, lightweight and stable energy supply system that can operate under extreme conditions to provide reliable protection for the safety and efficiency of operations in high-cold and hypoxic areas.

[0040] In view of this, in order to improve the integration of the energy supply backpack, the application embodiment proposes an oxygen-heat-electricity-hydrogen comprehensive energy supply backpack for high-cold and hypoxic areas. The backpack main body 1 includes a first chamber 12, a second chamber 13 and a third chamber 14. The inner wall of at least one of the first chamber 12, the second chamber 13 and the third chamber 14 is provided with a heat supply layer 15. The electrolysis assembly 2 is arranged in the first chamber 12. The electrolysis assembly 2 is used to electrolyze water to generate hydrogen and oxygen. The electrolysis assembly 2 has an oxygen outlet 121 and a hydrogen outlet 151. The hydrogen assembly 3 is arranged in the second chamber 13. The hydrogen assembly 3 includes a fuel cell 34. The fuel cell 34 is adapted to generate electricity by using the hydrogen gas discharged from the hydrogen outlet 151. The electrolysis of water to produce hydrogen and oxygen, the electricity generation of the fuel cell 34, the efficient heat supply and the preparation of hydrogen-rich water are integrated in a single backpack system. The problem of single function and equipment redundancy of traditional outdoor equipment is solved. Through the integration of functions such as oxygen and hydrogen production by water electrolysis, electricity generation and heating by the fuel cell 34, and heat supply by the heat supply layer 15, the oxygen and heat supply capacity in high-altitude, low-oxygen and high-cold environments is improved. The problem of dispersed energy supply is solved. The electrolysis assembly 2 consumes water to generate hydrogen and oxygen. The hydrogen is directly supplied to the fuel cell 34 to generate electricity. The sustainable supply of oxygen, heat energy, electricity and hydrogen-rich water is realized.

[0041] Next, according to the oxygen-heat-electricity-hydrogen comprehensive energy supply backpack for high-cold and hypoxic areas proposed by the application embodiment, the following is described.

[0042] In the first aspect, please refer to Figure 2 , Figure 3 , Figure 4 and Figure 11 , the application embodiment provides an oxygen-heat-electricity-hydrogen comprehensive energy supply backpack for high-cold and hypoxic areas, which includes a backpack main body 1, an electrolysis assembly 2, a hydrogen assembly 3 and a power supply assembly 4. The backpack main body 1 includes a first chamber 12, a second chamber 13 and a third chamber 14. The inner wall of at least one of the first chamber 12, the second chamber 13 and the third chamber 14 is provided with a heat supply layer 15. The electrolysis assembly 2 is arranged in the first chamber 12. The electrolysis assembly 2 is used to electrolyze water to generate hydrogen and oxygen. The electrolysis assembly 2 has an oxygen outlet 121 and a hydrogen outlet 151. The hydrogen assembly 3 is arranged in the second chamber 13. The hydrogen assembly 3 includes a fuel cell 34. The fuel cell 34 is adapted to generate electricity by using the hydrogen gas discharged from the hydrogen outlet 151. The power supply assembly 4 is arranged in the third chamber 14. The power supply assembly 4 includes a power supply battery 41 and a control circuit board 42. The power supply battery 41 and the fuel cell 34 are respectively electrically connected with the control circuit board 42. The control circuit board 42 is also electrically connected with the heat supply layer 15.

[0043] The high-cold hypoxia area-oriented oxygen-heat-electricity-hydrogen comprehensive energy supply backpack provided by the embodiment of the application integrates water electrolysis hydrogen-oxygen production, fuel cell 34 power generation and heating, and heat supply layer 15 efficient heat supply and hydrogen-rich water preparation in a single backpack system, improves the integration of the energy supply backpack, improves the richness of the functions of traditional outdoor equipment, and reduces equipment redundancy.

[0044] It can be understood that in a low-oxygen high-cold area, oxygen deficiency and low temperature often cause a large amount of physical consumption. The comprehensive energy supply backpack of the application can simultaneously provide oxygen and heat for the user, thereby eliminating the need to carry independent oxygen cylinders, generators, stoves and other equipment, significantly reducing the load, and simultaneously providing oxygen and heat for the user, ensuring stable operation of the human body core physiological function, relieving dizziness, fatigue, and excessive heart and lung load caused by oxygen deficiency, and reducing the energy consumed by the body to compensate for oxygen deficiency.

[0045] Hydrogen and oxygen are generated by consuming water through the electrolysis assembly 2, hydrogen is directly supplied to the fuel cell 34 for power generation, sustainable supply of oxygen, heat energy, electricity and hydrogen-rich water is achieved, the problem of dispersed energy supply is avoided, and the heat supply unit can supply heat as needed, thereby improving the oxygen and heat supply capacity in a high-altitude environment and a low-oxygen high-cold condition.

[0046] As an example, the heat supply unit can include graphene, and the temperature of the heat supply unit is adjustable. It can be understood that graphene has extremely high thermal conductivity, and electrical energy or other energy can be quickly converted into heat energy, and the heat is uniformly transferred, thereby reducing local heat loss. Compared with traditional resistance wires, carbon fibers and other materials, the heat conversion efficiency can be further improved.

[0047] In a specific embodiment, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the backpack body 1 includes a backpack shell 11, a first chamber 12, a second chamber 13, a third chamber 14, a heat supply layer 15, a storage chamber 16, a charging port 17, a shoulder strap 18 and a hand strap 19. The backpack shell 11 is made of lightweight composite material, has waterproof, cold-proof and impact-resistant functions, and is internally provided with a honeycomb structure shock-absorbing layer to enhance the overall structural strength. The heat supply layer 15 is arranged on the shock-absorbing layer of the first chamber 12, the second chamber 13 and the third chamber 14, and graphite heating sheets or PI heating films are arranged inside to realize electric heating, thereby providing stable heat in a low-temperature environment.

[0048] In other embodiments, a shock-absorbing layer is arranged in the backpack body 1, and the shock-absorbing chamber defines the first chamber 12, the second chamber 13 and the third chamber 14.

[0049] In the above scheme, the shock-absorbing partition layer can absorb impact force by itself deformation to provide buffer protection for the core components in the chamber, avoid line loosening, part falling off or shell damage caused by vibration, and prolong the service life of the equipment.

[0050] In other embodiments, the backpack body 1 is made of lightweight composite material, the outer side of the backpack body 1 is coated with waterproof and heat preservation material, and the shock-absorbing partition layer has at least one of a honeycomb structure, a foam filling structure and a micro air bag structure.

[0051] In the above scheme, the waterproof material coated on the outer side can block the penetration of liquid such as rainwater, dew and splashed water, avoid the short circuit of the circuit of the internal electrolysis assembly 2 due to moisture, and reduce the probability of water entering the drying device 35 of the fuel cell 34.

[0052] On the other hand, the heat preservation material can reduce the heat exchange between the inside and outside of the backpack, effectively recover the waste heat of each component during work, help to reduce the waste of heat in high-cold and low-pressure environment, and help to continuously heat the user in low-temperature environment.

[0053] At the same time, it can reduce the probability of electrolyte (water) freezing and electrode activity of the fuel cell 34 decreasing due to too low temperature, maintain the normal working temperature of the equipment, improve the utilization efficiency of internal heat, and the shock-absorbing partition layer can absorb high-frequency vibration and external impact to protect each component inside the backpack body 1.

[0054] In addition, when the shock-absorbing partition layer has at least one of a honeycomb structure, a foam filling structure and a micro air bag structure, on the one hand, it can efficiently absorb impact energy and improve the shock-absorbing effect, and on the other hand, it can greatly reduce the material density on the premise of ensuring the structural strength, thereby helping to improve the lightweight effect of the backpack, facilitating the use in low-oxygen and high-cold areas, and reducing the burden when used in low-oxygen and high-cold areas.

[0055] In other embodiments, please refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 , the electrolysis assembly 2 includes an electrolysis water bottle 22, a gas-liquid separator 23 and an electrolysis tank 24, the top of the separator is provided with a first opening 231, a second opening 233 and a third opening 232, the bottom of the separator is provided with a fourth opening 234, the fourth opening 234 is in communication with a water inlet 241 of the electrolysis tank 24, a water-hydrogen mixed outlet 242 of the electrolysis tank 24 is in communication with the second opening 233, the third opening 232 is in communication with a hydrogen outlet 151 of the electrolysis assembly 2, and an oxygen outlet 243 of the electrolysis tank 24 is in communication with an oxygen outlet 121.

[0056] In the above scheme, when the electrolytic cell 24 is working, electrolysis of water produces hydrogen gas, oxygen gas and unreacted water to form a "water-hydrogen mixture". The gas-liquid separator 23 can effectively remove the liquid water in the hydrogen gas to avoid water entering the fuel cell 34 in the second chamber 13, reduce the probability of electrode short circuit and improve the stability of power generation. The oxygen outlet 243 of the electrolytic cell 24 is directly communicated with the oxygen outlet 121 to reduce the mixing probability with hydrogen and water and ensure the purity of oxygen. The fourth opening 234 at the bottom of the liquid separator is communicated with the first opening of the electrolytic cell 24, which means that the unreacted water settled in the separator can flow back to the electrolytic cell 24 to participate in electrolysis again, reducing water waste, helping to prolong the use time of single water supply and reducing the frequency of replenishment.

[0057] In other embodiments, referring to Figure 5 , a first pipeline is arranged between the water-hydrogen mixture outlet 242 of the electrolytic cell 24 and the second opening 233, and the first pipeline is provided with a first circulating pump 25.

[0058] In the above scheme, the first circulating pump 25 provides additional power for the mixture by active pressurization, ensuring that the mixture quickly and stably enters the gas-liquid separator 23 through the first pipeline, which helps to improve the bubble detachment efficiency and ensure rapid bubble detachment, solving the problem of slow bubble detachment and low hydrogen production efficiency in low-pressure environments.

[0059] It can be understood that in low-pressure environments such as high altitudes, the hydrogen gas bubbles generated in the process of electrolytic water hydrogen production have reduced buoyancy in the electrolyte due to the low pressure below the standard atmospheric pressure, resulting in a significant slowdown in bubble detachment speed. The first circulating pump 25 of the present application can provide additional power for the mixture to increase the flow rate of the mixture, quickly bring the suspended bubbles into the gas-liquid separator, reduce the residence time of the bubbles, and at the same time accelerate the reflux of unreacted electrolyte to the electrolytic cell, improving the overall material circulation efficiency.

[0060] That is, the forced transport of the circulating pump can accelerate the circulation speed of unreacted water from the electrolytic cell 24 to the separator and then back to the electrolytic cell 24, reducing the probability of slow or even stagnant flow of the mixture due to the increase in water viscosity in high-altitude, low-temperature or low-pressure environments.

[0061] In other embodiments, the electrolytic water bottle 22, the gas-liquid separator 23 and the electrolytic cell 24 are arranged in the first chamber 12 from top to bottom.

[0062] In the above scheme, the electrolysis water bottle 22 is located at the top as the water source, so that the water flows downward naturally under the action of gravity into the gas-liquid separator 23, without the need for additional power to supplement the water in the circulation system, reducing the energy consumption required by the system, and the water-hydrogen mixture enters the gas-liquid separator 23 in the middle from the electrolysis tank 24 located below. When the gas-liquid separator 23 is located higher, the mixture can enhance the separation effect in the rising process with the help of gravity difference, and the liquid is more easily settled at the bottom under the action of gravity, and the hydrogen with smaller density is more easily floated to the top and discharged, reducing the dependence on the circulating pump.

[0063] In other embodiments, the oxygen outlet 121 of the electrolysis tank 24 is connected to the quick connection interface provided on the backpack main body 1 through a pipeline, and the quick connection interface is used to connect the quick connection joint of the external oxygen inhalation equipment.

[0064] In the above scheme, the quick connection interface can be connected without tools, and can quickly supply oxygen to oxygen cylinders, masks and other equipment, improving the operation efficiency.

[0065] In other embodiments, please refer to Figure 7 A liquid level sensor 27 is provided in the gas-liquid separator 23, and the liquid level sensor 27 is connected to the control circuit board 42 through a signal line.

[0082] Please refer to Figure 12 The working principle of the oxygen-thermal-electric-hydrogen comprehensive energy supply backpack described in the present application is briefly described as follows: Pure water is added to the electrolytic water bottle 22; after the power supply assembly 4 is started, the pure water in the electrolytic water bottle 22 flows into the electrolytic cell 24 through the gas-liquid separator 23; in the electrolytic cell 24, hydrogen and oxygen are generated after the water is electrolyzed, the hydrogen and the unreacted pure water flow into the gas-liquid separator 23 through the first circulating pump 25, and the oxygen is directly supplied to the user through the pipeline; the hydrogen is separated from the water in the gas-liquid separator 23, is input into the drying device 35 through the hydrogen conveying pump 26 for water removal, and is then stably conveyed to the drinking water bottle 32 and the fuel cell 34; part of the hydrogen forms hydrogen-rich water in the drinking water bottle 32 through the nano gas disc 33, and the other part of the hydrogen enters the fuel cell 34; the electric energy generated by the fuel cell 34 is supplied to the heat supply layer 15 and an external load; the heat generated by the heat supply layer 15 is supplied to the storage cavity 16, the electrolysis assembly 2, the hydrogen use assembly 3 and the energy supply assembly 4.

[0083] The energy supply backpack can be applied in the fields of hydrogen fuel cell bicycles, hydrogen fuel cell unmanned aerial vehicles, communication base stations, vehicle-mounted hydrogen and oxygen supply systems and portable power sources by virtue of the portable and movable characteristics of the energy supply backpack, and the present application does not limit this.

[0084] In another specific embodiment, the overall outer dimensions of the backpack body 1 are 450 mm (high) x 360 mm (wide) x 230 mm (thick), wherein the effective volume of the first cavity 12 is 2.2 L (440 x 50 x 100 mm), the effective volume of the second cavity 13 is 2.2 L (440 x 50 x 100 mm), and the effective volume of the third cavity 14 is 4.8 L (100 x 240 x 100 mm). The cavities are physically isolated by reinforced isolation pads, and the isolation pads have a thickness of 5 mm and are provided with a shock-absorbing honeycomb structure.

[0085] Meanwhile, the electrolytic cell is made of an organic polymer material, and the weight is about 800 g. Compared with the electrolytic cell made of a traditional metal material, the weight of the electrolytic cell is greatly reduced, the weight of the entire backpack is further reduced, the weight of the entire backpack is about 3 kg, the lightweight degree is improved, and the use is facilitated.

[0086] The current density of the electrolytic cell can be 500 mA / cm 2 , the electrolysis period can be shortened, the hydrogen production is improved, the energy utilization rate is optimized, and the overall energy efficiency of the backpack is higher.

[0087] 1. Hydrogen and oxygen production calculation: the effective area A of the anion exchange membrane electrolytic cell 24, which is the core component of the electrolysis assembly 2, is 64 cm 2 , and the current density j is 500 mA / cm 2 . Using 15 lithium batteries with a capacity of 5000 mA, the electrolytic cell can stably work for at least 2 hours.

[0088] According to I = j x A, it can be obtained that I=500mA / cm 2 ×64cm 2 =32000mA=32A According to Faraday's law, combined with the cathode and anode electrode reaction formula, the number of moles of hydrogen n1 and oxygen n2 generated per minute is: Then the volume V1 of hydrogen generated per minute under standard conditions is: V1=9.95×10 -3 mol×22.4L / mol≈0.223L Then the volume V2 of oxygen generated per minute under standard conditions is: V2=4.98×10 -3 mol×22.4L / mol≈0.111L That is, the product described in the present application can generate 0.223L of hydrogen and 0.111L of oxygen per minute.

[0089] 2. Hydrogen use: fuel cell power P=20W, fuel cell efficiency η=0.50, output voltage U=5V, output current I=4A; According to the "Fuel Cell Engine Performance Test Method" GB / T24554-2022, the fuel cell efficiency calculation formula is: Where: is the hydrogen mass flow rate, is the hydrogen low heat value (HHV) ) Then the hydrogen mass flow rate required is is: Then the hydrogen volume flow rate required under standard conditions is is: Then the volume V3 of hydrogen required per minute under standard conditions is: V3=0.222L; Since the amount of hydrogen used in the drinking water bottle 32 is very small, it can be ignored when calculating the hydrogen consumption; therefore, the hydrogen generated by the electrolytic tank 24 in this embodiment can supply the 20W fuel cell to work normally.

[0090] The electric heating device of the heat supply layer 15 adopts two graphene heating sheets with a length of 20 cm and a width of 10 cm. When there is an external load, the fuel cell outputs 10 W of electricity to the external load, and the remaining 10 W of electricity is output to one of the graphene heating sheets, so that it is heated for a short time and kept at about 60 DEG C; when there is no external load, the fuel cell can selectively output 20 W of electricity to the two graphene heating sheets, so that the two graphene heating sheets are rapidly heated to 60 DEG C at the same time, or the fuel cell can selectively output 20 W of electricity to one of the graphene heating sheets, so that the graphene heating sheet is rapidly heated to 110 DEG C 3. Oxygen supply: According to the Design Standard for Civil Oxygen Supply Project in Tibet Autonomous Region DBJ540004-2018, at an altitude of 3000 meters, the oxygen partial pressure in the air is 109.9 mmHg, and the equivalent concentration of oxygen is 14.46%. Compared with sea level, the oxygen concentration is about 70% of the sea level concentration, so 30% of oxygen needs to be supplemented to meet the demand. When the human body is engaged in standing and relaxing activities, the total oxygen consumption of the human body is 0.36 NL / min, so at an altitude of 3000 meters, 0.108 NL / min of oxygen needs to be supplemented to maintain normal metabolism.

[0091] Therefore, the oxygen-heat-electricity-hydrogen comprehensive energy supply backpack for alpine hypoxic areas in the embodiment can meet the oxygen demand of the user in the standing or relaxing state at an altitude of 3000 meters, and simultaneously provide electric energy, heat energy and hydrogen-rich water, so as to achieve the expected comprehensive energy supply effect.

[0092] Based on the above description, the oxygen-heat-electricity-hydrogen comprehensive energy supply backpack based on the water electrolysis technology can solve the problems of insufficient oxygen, insufficient heat supply and low energy utilization rate in extreme environments in a portable manner, not only provides efficient oxygen supply, but also provides certain heat energy support for the user, and ensures the basic survival needs of personnel in extreme environments such as high cold and high altitude. In addition, the device also solves the problem of dispersed energy supply through innovative integrated design, optimizes the energy utilization efficiency of the device, and can provide stable multiple energy support for personnel within a certain period of time.
