Description

Technical Field

[0001] This invention patent relates to the field of electrochemical technology, and more specifically, to a thermoelectric membrane fuel cell. Background Technology

[0002] A proton exchange membrane fuel cell (PEMFC) is a type of fuel cell. As a truly green and environmentally friendly energy source, its extremely high theoretical specific energy (for the hydrogen-air system, its theoretical specific energy is as high as 32940 WhP kg, far exceeding any other existing chemical power source) is considered to be one of the main power sources for future transportation, distributed power stations, and various electronic products.

[0003] Features

[0004] (1) High energy conversion efficiency. Chemical energy is directly converted into electrical energy through hydrogen hydration, without going through a heat engine process and not being limited by the Carnot cycle.

[0005] (2) It can achieve zero emissions. Its emissions are pure water (and water vapor), with no pollutant emissions, making it an environmentally friendly energy source.

[0006] (3) Low operating noise and high reliability. PEMFC battery packs have no mechanical moving parts, and only gas and water flow during operation.

[0007] (4) Easy to maintain. The internal structure of PEMFC is simple, and the battery modules present a natural "building block" structure, which makes the assembly and maintenance of the battery pack very convenient; it is also easy to achieve "maintenance-free" design.

[0008] (5) Its power generation efficiency is minimally affected by load changes, making it ideal for use as a distributed power generation unit (as the main unit) and also suitable for use as a "peak shaving" generator unit for the power grid (as an auxiliary unit).

[0009] (6) Hydrogen is the most abundant element in the world, and its sources are extremely wide. It is a renewable energy resource that is inexhaustible. Hydrogen can be produced by reforming petroleum, natural gas, methanol, methane, etc.; it can also be obtained through methods such as water electrolysis, photocatalytic water splitting, and biological hydrogen production.

[0010] (7) The technologies for the production, storage, transportation and use of hydrogen are now very mature, safe and reliable.

[0011] Fuel cells use hydrogen as fuel. In the next 5-10 years, hydrogen production will likely remain primarily from fossil fuel reforming; however, in the long term, hydrogen is increasingly seen as an energy storage medium, and its source will mainly rely on renewable energy resources. Once humanity enters the hydrogen economy era, hydrogen energy will primarily come from solar, wind, hydro, geothermal, tidal, and bioenergy sources. Solar, wind, hydro, geothermal, and tidal energy will be used extensively for power generation and water electrolysis, thus storing large quantities of this non-directly storable energy in the form of hydrogen for use when needed. Furthermore, through bio-hydrogen production methods, urban and rural areas can obtain significant amounts of bioenergy (such as methane) from organic waste and plant matter.

[0012] Advantages of fuel cells:

[0013] 1. Its power generation process does not involve the combustion of hydrogen and oxygen, and therefore is not limited by the Carnot cycle, resulting in a high energy conversion rate;

[0014] 2. It generates no pollution during power generation, the power generation unit is modular, highly reliable, easy to assemble and maintain, and operates without noise. Therefore, the proton exchange membrane fuel cell power supply is a clean, efficient, and environmentally friendly power source.

[0015] 3. Proton exchange membrane fuel cells have low operating temperature, fast start-up, high specific power, simple structure, and convenient operation.

[0016] 4. It is widely recognized as an energy source for electric vehicles, stationary power plants, etc. Inside a fuel cell, the proton exchange membrane provides a channel for the migration and transport of protons, allowing protons to pass through the membrane from the anode to the cathode, forming a loop with the electron transfer in the external circuit to provide current to the outside. Therefore, the performance of the proton exchange membrane plays a very important role in the performance of the fuel cell, and its quality directly affects the battery's lifespan.

[0017] Currently, proton exchange membrane fuel cells (PEMFCs) suffer from significant heat waste, and fuel utilization efficiency needs improvement. The membrane structure still utilizes a laboratory bipolar plate design, which is prone to leaks during operation, requiring frequent maintenance. The bipolar plate structure is also simplistic and lacks safety. Furthermore, fuel cell manufacturing costs are prohibitively high. Summary of the Invention

[0018] To solve the above problems, the present invention adopts the following technical solution.

[0019] In some embodiments, the proton exchange membrane layer is clamped by two semi-circular tubes. A transversely corrugated anode layer and a transversely corrugated cathode layer are used to bond and fix the proton exchange membrane layer together with the two semi-circular tubes around the perimeter. The thermoelectric power generation chip membrane is first bonded to the top and bottom surfaces with thermally conductive adhesive, and then a polysulfone layer is bonded. The layers are then rotated and wound around the circular axis formed by the two semi-circles to form a fuel cell membrane roll. Finally, end caps are attached to both ends of the membrane roll, and an outer tube is wound around a fiberglass shell to form a thermoelectric power generation membrane tube fuel cell core. Multiple thermoelectric power generation membrane tube fuel cell cores are installed in a stainless steel membrane shell to form the finished membrane tube fuel cell.

[0020] In some embodiments, the two semicircular tubes have small vent holes distributed on the tube walls at both ends of the portion where they overlap with the proton exchange membrane, and the interior of each semicircular tube is sealed with adhesive. These vent holes are distributed on both sides of the centerline of the square proton exchange membrane, and their length extends beyond the proton exchange membrane.

[0021] In some embodiments, the cooling water flows in from one end face of the thermoelectric membrane tube fuel cell and flows out from the other end face, and then reaches the surface of the thermoelectric chip membrane layer through the water supply channel of the polysulfone support layer, using the temperature difference between the cooling water and the anode layer and cathode layer to generate thermoelectric power.

[0022] In some embodiments, inside the thermoelectric membrane tube fuel cell, apart from a 45-60 micrometer thick polysulfone support layer serving as a water inlet barrier, all other membrane components are sequentially bonded together after being coated with insulating and waterproof adhesive around their perimeters. All layers are then wound onto two semi-circularly combined shafts to form a thermoelectric membrane tube fuel cell roll. Finally, end caps are attached to both ends of the roll, and fiberglass is wound around the outside to form the thermoelectric membrane tube fuel cell core. The thermoelectric membrane tube fuel cell core is then installed in the membrane housing to constitute the finished thermoelectric membrane tube fuel cell.

[0023] In some embodiments, the anode and cathode layers inside the thermoelectric membrane tube fuel cell are provided with air guiding channels on the side near the proton exchange membrane, and airflow channels for hydrogen and oxygen (air) are formed between the anode and cathode layers and the proton exchange membrane inside the thermoelectric membrane tube fuel cell.

[0024] In some embodiments, the internal semi-circular tube of the thermoelectric membrane fuel cell is made of plastic, ceramic, or metal.

[0025] In some embodiments, a thermoelectric film layer is provided between the cooling water polysulfone layer and the anode and cathode plates. The thermoelectric film is bonded and fixed to the anode and cathode layers with thermally conductive adhesive.

[0026] In some embodiments, each end of the thermoelectric membrane tube fuel cell core is provided with two sets of connecting wires. One set is for the positive and negative electrode wires of the hydrogen fuel cell, and the other set is for the positive and negative electrode wires of the thermoelectric chip. One end of the connecting wire of the membrane tube fuel cell core is connected to a waterproof male connector, and the other end is connected to a waterproof female connector. This facilitates the series connection of several thermoelectric membrane tube fuel cell cores into a single membrane housing. The beneficial effects of the embodiments of this disclosure are as follows: The thermoelectric membrane tube fuel cell of the present invention is formed by laminating and sealing the proton exchange membrane, positive and negative electrode layers, thermoelectric membrane, and polysulfone layer together, then winding all the layers onto two semi-circularly combined shafts to form a thermoelectric membrane tube fuel cell roll, finally attaching end caps to both ends of the roll, and then winding the outer tube around a fiberglass shell to form a thermoelectric membrane tube fuel cell core. The thermoelectric membrane tube fuel cell core is then installed in the membrane housing to constitute the finished thermoelectric membrane tube fuel cell. This thermoelectric membrane fuel cell features high integration, low noise, small size, and good sealing. It can also flexibly adjust the hydrogen circulation volume according to the output power requirements of the hydrogen fuel cell device, and can be connected in series or parallel at will. The membrane tubes can be freely combined to make full use of the thermoelectric power generation of the fuel cell, thereby improving energy efficiency and having strong industrial application value.

Obviously, the described embodiments are merely some embodiments of this specification, and not all embodiments.

[0034] Proton exchange membrane fuel cells (PEMFCs) are simple in structure and easy to use and maintain. They do not require boilers, turbines, generators, or other equipment. Fuel utilization is high, typically 50%-70%. They operate without noise and do not pollute the environment. Hydrogen fuel cells can provide continuous, high-power electricity. Because fuel cells directly convert chemical energy into electrical energy, they are not limited by the Carnot cycle thermal efficiency. However, with current technology, a significant amount of heat is wasted in PEMFCs, and fuel utilization needs improvement. The membrane structure still uses a laboratory bipolar plate design, making it prone to leaks and requiring frequent maintenance during operation.

[0035] Furthermore, the safety of current hydrogen fuel cell technology still has safety flaws. If hydrogen leaks into the fuel cell, the danger is extremely high.

[0036] Furthermore, since hydrogen fuel cells are mostly used in mobile transportation, how to ensure safety in the event of a traffic accident is a question that deserves our serious consideration.

[0037] Furthermore, the energy conversion efficiency of hydrogen fuel cells needs further improvement.

[0038] Finally, there's the cost of hydrogen fuel cells. Cheapness, energy efficiency, high efficiency, and safety are the technical parameters we really need to consider.

[0039] To address the aforementioned problems in the prior art, this disclosure provides a thermoelectric membrane tube fuel cell, comprising: a proton exchange membrane layer clamped by two semi-circular tubes; an anode layer with transverse corrugations; and a cathode layer with transverse corrugations. The proton exchange membrane layer, along with the two semi-circular tubes, is glued and fixed around the perimeter. A thermoelectric chip membrane is first bonded to the top and bottom surfaces with thermally conductive adhesive, followed by a polysulfone layer. The layers are then wound around a circular axis formed by the two semi-circles to form a fuel cell membrane roll. Finally, end caps are attached to both ends of the membrane roll, and an outer tube is wound around a fiberglass shell to form a thermoelectric membrane tube fuel cell core. Multiple thermoelectric membrane tube fuel cell cores are then housed in a stainless steel membrane shell to constitute the finished membrane tube fuel cell. Figure 1 As shown.

[0040] Figure 1 A side cross-sectional view of the thermoelectric membrane tube fuel cell in this embodiment is shown. In this embodiment, hydrogen and oxygen (air) enter the semicircular tube from semicircular tubes 6 and 7, respectively. The middle of the semicircular tube is sealed with sealant 25. After the hydrogen and oxygen (air) flow out through the small vent holes 23 at both ends of the semicircular tube, they enter the airflow channel 21 of the positive electrode layer and the negative electrode layer 22, and then flow into the semicircular tube through the small vent hole 23 at the other end of the semicircular tube. They then flow directly out of the semicircular tube and enter the next thermoelectric membrane tube fuel cell or the gas pump pumps the gas back to the gas storage container.

[0041] In this embodiment, the front edge 24 of the positive and negative electrode layers with airflow channels is bonded and fixed together with the edge of the proton exchange membrane and the semi-circular tube 20, while the back edge of the positive and negative electrode layers is bonded and fixed with the thermoelectric chip film layer by coating the entire surface with thermally conductive and curable adhesive.

[0042] In this embodiment, 1 is the proton exchange membrane layer, 2 is the anode layer, 3 is the cathode layer, 4 is the thermoelectric power generation membrane layer, 5 is the polysulfone layer, and the outermost layer is a fiberglass protective layer. Cooling water flows into the thermoelectric power generation membrane tube fuel cell from one end, passes through the polysulfone water-conducting layer, and flows out from the other end.

[0043] 9. In this embodiment, each end of the thermoelectric membrane tube fuel cell core is provided with two sets of connecting wires 10 and 11. One set is for the positive and negative electrode wires of the hydrogen fuel cell power generation, and the other set is for the positive and negative electrode wires of the thermoelectric chip power generation. One end of the connecting wire of the membrane tube fuel cell core is connected to a waterproof male connector, and the other end is connected to a waterproof female connector. This facilitates the connection of several thermoelectric membrane tube fuel cell cores in series and then installed in a membrane housing.

[0044] Figure 2 The diagram shows the cross-sectional membrane winding structure of a thermoelectric membrane tube fuel cell.

[0045] In this embodiment, 1 is a proton exchange membrane, 2 is an anode layer, 3 is a cathode layer, 4 is a thermoelectric membrane, 5 is a polysulfone layer, 6 is a hydrogen inlet, 7 is an oxygen inlet, 8 is a hydrogen semi-circular tube, and 9 is an oxygen semi-circular tube.

[0046] In this embodiment, the proton exchange membrane layer 1 is clamped by two semi-circular tubes 8 and 9. The anode layer 2 with transverse corrugations and the cathode layer 3 with transverse corrugations are glued and fixed together around the proton exchange membrane layer 1 and the two semi-circular tubes 8 and 9. The thermoelectric power generation chip membrane 4 is first glued to the top and bottom with thermally conductive adhesive and then the polysulfone layer is glued on. The membrane layer is rotated and wound around the circular axis formed by the two semi-circles to form a fuel cell membrane roll.

[0047] In this embodiment, hydrogen is oxidized into ions and electrons at the anode layer, while oxygen is reduced to water at the cathode. Ions are transferred to the cathode via the electrolyte, while electrons are transferred to the anode via an external circuit, forming an electric current. Due to the potential difference generated by the redox reaction, the current can be used to drive external circuits and devices.

[0048] In this embodiment, the proton exchange membrane 1 of the hydrogen fuel cell is a composite of the anode, cathode, and electrolyte, consisting of a proton exchange membrane, porous gas diffusion electrodes (porous carbon cloth coated with catalyst) on both sides of the membrane, and the electrolyte. The electrodes of the hydrogen fuel cell are typically made of noble metals such as platinum, palladium, rhodium, and titanium. The noble metal catalyst on the anode promotes the oxidation reaction of hydrogen, thereby generating electrons. The noble metal catalyst on the cathode promotes the reduction reaction of oxygen, thereby accepting electrons and forming water. The physical isolation between the electrodes and the electrolyte prevents an explosion caused by the mixing of oxygen and hydrogen.

[0049] In this embodiment, instead of the bipolar plates of a traditional hydrogen fuel cell, there are anode and cathode layers. The anode and cathode layers are preferably made of graphite or graphene carbon composite materials that have fast thermal conductivity and strong electrical conductivity.

[0050] In this embodiment, hydrogen input is a crucial component of hydrogen fuel cell operation. Typically, hydrogen is stored in pressurized cylinders and piped to the anode. To ensure the purity and quality of the hydrogen input, a hydrogen purification system is usually required. This system removes impurities and impurities, improving the purity and quality of the hydrogen and thus ensuring proper battery operation.

[0051] Figure 3 Diagram of the anode and cathode layer structure of a thermoelectric membrane tube fuel cell.

[0052] In this embodiment, the middle of the semicircular tube 20 is sealed with a curing adhesive 25. At both ends of the semicircular tube 20, away from the adhesive joint, are numerous airflow holes and guide channels. Hydrogen and oxygen (air) enter the semicircular tube from the semicircular tubes 6 and 7 respectively. The middle of the semicircular tube is sealed with sealant 25. After flowing out through the small ventilation holes 23 at both ends of the semicircular tube, the hydrogen and oxygen (air) enter the airflow channels 21 of the positive and negative electrode layers 22, then flow back into the semicircular tube through the ventilation hole 23 at the other end, and flow directly out of the semicircular tube into the next thermoelectric membrane fuel cell or a gas pump to pump the hydrogen back into the storage container.

[0053] In this embodiment, each end of the thermoelectric membrane tube fuel cell core is provided with two sets of connecting wires 10 and 11. The positive and negative terminals of 10 are connected to the positive and negative electrode layers, respectively, and the positive and negative terminals of 11 are connected to the positive and negative terminals of the thermoelectric chip. One set is for the positive and negative terminals of the hydrogen fuel cell, and the other set is for the positive and negative terminals of the thermoelectric chip. One end of the connecting wire of the membrane tube fuel cell core is connected to a waterproof male connector, and the other end is connected to a waterproof female connector. This facilitates the connection of several thermoelectric membrane tube fuel cell cores in series and then assembled into a single membrane housing.

[0054] In this embodiment, the thermoelectric membrane tube fuel cell with a catalyst layer electrode thickness of 8 μm exhibits the highest power output. Reducing the membrane thickness is beneficial for improving the cell's performance, and as the catalyst layer thins, the amount of catalyst used also decreases, which not only reduces costs but also improves cell performance. At the same current density, the single-cell voltage of the thermoelectric membrane tube fuel cell tends to increase with increasing air humidity, reaching its maximum value at a relative humidity of 80%. The proton exchange membrane requires water to maintain its proton conductivity; higher air humidity increases the water content of the proton exchange membrane, enhancing its conductivity, reducing the impedance across the membrane, accelerating the hydrogen ion transfer rate within the membrane, and thus improving the electrochemical reaction rate and the output performance of the thermoelectric membrane tube fuel cell. Furthermore, the improvement in output performance is more pronounced with increasing output current because as the current density increases, more water is produced by the chemical reaction, leading to a gradual increase in humidity within the stack, resulting in better output performance. The effect of temperature on the performance of the thermoelectric membrane tube fuel cell is mainly manifested in its influence on gas diffusion capacity and membrane proton conductivity. When the fuel cell stack temperature is between 55℃ and 65℃, the power output of the fuel cell increases with increasing temperature. This is because at low temperatures, water mostly exists in the form of small droplets, with little gaseous component and low saturation pressure. At this temperature, water flooding occurs at the membrane electrode assembly (MEA), making it difficult for O2 to enter the catalyst layer from the diffusion layer, thus affecting the electrochemical reaction rate. As the stack temperature increases, the catalyst activity significantly increases. Simultaneously, the temperature increase also increases the water and gas diffusion coefficients within the membrane, thereby reducing membrane resistance and improving output performance. When the fuel cell temperature exceeds 70℃, the power output of the fuel cell decreases with increasing temperature. This is because when the stack temperature is too high, water on the proton exchange membrane easily evaporates, leading to a decrease in membrane humidity. Lower membrane humidity increases membrane resistance, reducing its efficiency in transporting hydrogen ions, thus affecting the stack performance. Therefore, during fuel cell operation, the stack temperature needs to be properly controlled by the cooling system. Above 65℃, thermoelectric generators should be activated promptly to accelerate the cooling water flow. During fuel cell operation, liquid water is generated in the porous medium of the battery plates, especially the cathode. The presence of liquid water reduces the porosity of the porous electrode and increases the gas conduction resistance in the diffusion layer. Increasing the air flow helps to remove liquid water from the electrode, improves porosity, increases the diffusion coefficient, and thus improves the performance of the battery.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure, and not to limit them. Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this disclosure. For example, multiple proton exchange membranes and membrane assemblies are simultaneously rotated and wound.
