[0002] After years of development, fuel cell technology has gradually entered the early stages of commercialization. In recent years, the demand for high-power fuel cells in electric vehicles has become increasingly urgent. The membrane electrode is the core component of a fuel cell. The proton exchange membrane (PEM) conducts protons and blocks anode and cathode gases. Proton conduction within the PEM requires water. Humidification of the reactant gases is necessary to maintain a well-hydrated PEM and maintain high proton conductivity, thereby improving the output performance and service life of the fuel cell. This ensures fuel cell system efficiency and extends its lifespan.

[0003] When a humidifier is in use, dry air and moisture flow through it. Therefore, the membrane tubes must be plugged and then sealed with glue to prevent the dry air and moisture from mixing. However, traditional plugging and glue filling are two separate processes, using different tooling, which is relatively time-consuming and complex. Utility Model Content

[0004] To address the aforementioned issues, the present application provides a glue-filling device for a fuel cell membrane humidifier. By disposing a glue-filling container on the housing, the device first injects glue into the housing to seal the ends of the membrane tubes, effectively plugging the holes. The device then uses the glue-filling container to inject glue into the housing to form a sealing surface. This allows for continuous plugging and glue-filling processes, utilizing the same device. This eliminates the need for disassembly or replacement of tooling, reducing both process time and complexity.

[0019] This application has at least the following beneficial effects:

[0020] 1. The present application provides a glue-filling device for a fuel cell membrane humidifier, comprising a housing and two glue-filling containers. Multiple membrane tubes for conveying dry gas can be placed inside the housing, and the glue-filling containers are connected to both ends of the housing, respectively, to seal the first opening and the second opening.

Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0032] Among related technologies, hydrogen energy is one of the most promising new energy sources. Hydrogen produced in various ways can be directly converted into electricity through fuel cells. This can be used in vehicles such as cars and trains to achieve zero terminal pollutant emissions. It can also be used in stationary power generation and heating facilities such as industrial, commercial, and residential buildings. Proton exchange membrane fuel cells (PEMFCs) are a new type of green power source with low operating temperatures, no corrosion issues, high current density, and fast response speed. They are highly favored in many applications in the military, aerospace, and automotive industries, demonstrating excellent performance and strong vitality. PEMFCs have made significant progress over the past decade and have become a dominant force in vehicle fuel cell engines.

[0033] After years of development, fuel cell technology has gradually entered the early stages of commercialization. In recent years, the demand for high-power fuel cells in electric vehicles has become increasingly urgent. The membrane electrode is the core component of a fuel cell. The proton exchange membrane (PEM) conducts protons and blocks anode and cathode gases. Proton conduction within the PEM requires water, necessitating humidification of the reactant gases to maintain a well-hydrated PEM and maintain high proton conductivity. This improves the fuel cell's output performance and service life, ultimately guaranteeing the efficiency of the fuel cell system.

[0034] The general method for humidifying the reaction gas is to set up a humidifier, and set up a membrane tube for the flow of dry gas in the humidifier. There is moisture flowing inside the humidifier, and the reaction gas is humidified according to the principle of heat and moisture exchange. Usually, in order to avoid the mixing of moisture and dry gas after flowing, it is necessary to plug the holes in the membrane tube and then fill the membrane humidifier with glue to seal the membrane tube and the inner wall of the humidifier. However, in the traditional plugging process, plugging and filling are two independent processes, which require the use of two different toolings, are relatively time-consuming, and the process flow is relatively complicated. In addition, the traditional plugging process mainly uses putty and hot melt adhesive as plugging materials, which not only have poor bonding effect, but the formed adhesive layer is also easy to fall off, and the membrane tube opening effect after cutting is poor, which affects the circulation of dry gas in the membrane wire, thereby affecting the performance of the fuel cell membrane humidifier.

[0035] Based on the above problems, the present application embodiment proposes a glue filling device for a fuel cell membrane humidifier, see Figure 1 and Figure 2 , specifically including:

[0036] A housing 1 for placing a film tube 14 and two glue-filling containers 2;

[0037] The shell 1 is provided with a first opening 11 and a second opening 12 at both ends thereof. The glue pouring container 2 is connected to the ends of the shell 1 and blocks the first opening 11 and the second opening 12 respectively. The glue pouring container 2 is used for pouring glue into the shell 1 .

[0038] During implementation, the membrane tube 14 is placed within the housing 1, and the glue potting containers 2 are then fixedly connected to both ends of the housing 1, sealing the first opening 11 and the second opening 12. When installing the glue potting containers 2, the ends of the membrane tube 14 are aligned with the glue potting containers 2 at both ends of the housing 1. This ensures that the potting glue reaches both ends of the membrane tube 14 during potting, ensuring both hole plugging and glue potting. This device features a simple structure, is easy to install, and is highly practical.

[0039] See also Figure 2 When pouring glue, first add a certain amount of potting glue into the potting container 2 at one end of the shell 1, so that the potting glue is poured from bottom to top in the shell 1 for the first time, and the two ends of the membrane tube 14 are sealed. After the potting glue is solidified, a first glue layer 18 is formed; then the second potting is carried out, and a certain amount of potting glue is added to the potting container 2 again, so that the potting glue is transported from bottom to top in the shell 1, and the gap between the shell 1 and the membrane tube 14 is sealed. After the potting glue is solidified, a second glue layer 19 is formed; then the potting container 2 at one end of the shell 1 is removed, and the first glue layer 18 and the corresponding membrane tube 14 in the glue layer are cut off, and then the second glue layer 19 of a certain height is cut off from bottom to top to expose the air inlet of the membrane tube 14, ensuring that the sealing between the outer wall of the membrane tube 14 and the shell 1 is not affected. Except for the openings at both ends of the membrane tube 14, the rest of the shell end face is sealed, thereby completing the hole plugging and glue pouring. After one side of the shell 1 is completed, the shell 1 is turned upside down and the above operation is repeated on the other end of the shell 1, so that both ends of the membrane tube 14 in the shell 1 are processed with plugging and glue filling.

[0040] By providing the glue pouring container 2, when pouring glue into the housing 1, the same glue pouring container 2 can be used for two consecutive pouring operations, eliminating the need for two toolings for pouring glue, avoiding the need for disassembly and assembly, simplifying the glue pouring process, and shortening the processing time. Furthermore, using the same glue pouring container 2 for two pouring operations combines the hole plugging and the pouring of the sealant layer into a continuous step, thereby improving the processing effect.

[0041] In specific implementation, the connection method between the glue filling container and the shell includes threaded connection, snap connection, bolt connection, etc., which can fix the glue filling container on the shell and seal the shell. The specific connection method is not specifically limited in the embodiment of this application.

[0042] During specific implementation, the same potting glue is used for the first and second potting processes. Compared with the traditional process of using different potting glues for plugging holes and potting, the embodiment of the present application has a better hole plugging effect, the glue layer is less likely to fall off, the sealing effect is better, and the curing time is short, which can shorten the process time.

[0043] In practice, the potting adhesive of the present application embodiment uses one or both of polyurethane and epoxy resin. Compared to the traditional process of using putty or hot melt adhesive as a pore-blocking material, the adhesive layer prepared in the present application embodiment has a better effect of opening the membrane tube 14 after cutting, and has a smaller impact on the circulation of dry gas within the membrane filament, thereby reducing the impact on the performance of the fuel cell membrane humidifier.

[0044] In specific implementation, epoxy resin is preferably used. After curing, epoxy resin has high adhesive strength and cohesive strength, which can ensure that the fuel cell membrane humidifier maintains stable sealing performance under harsh operating conditions such as high pressure and high temperature. In specific implementation, after the glue filling is completed, the glue filling containers 2 at both ends of the shell 1 are removed, and the shell 1 can continue to be used as the outer shell of the fuel cell membrane humidifier.

[0045] In some embodiments, see Figure 3 After the glue filling is completed, the shell 1 can be used as the outer shell of the membrane humidifier. Specifically, after the glue filling container 2 is removed, end caps 15 are installed at both ends of the shell 1. A dry gas inlet 151 and a dry gas outlet 152 are set on the end caps 15. The two ends of the membrane tube 14 are respectively connected to the dry gas inlet 151 and the dry gas outlet 152 to transport dry gas. Then, a wet gas inlet 16 and a wet gas outlet 17 are opened on the shell 1. Dry gas enters the membrane tube 14 along the dry gas inlet 151, and wet gas enters the shell 1 along the wet gas inlet 16. Since the shell 1 has been plugged and glued, the wet gas will not enter the membrane tube 14 along the end of the membrane tube 14. The dry gas and wet gas can be well separated, so that the wet gas outside the membrane tube 14 humidifies the dry gas inside the membrane tube 14. The dry gas is humidified and then discharged along the dry gas outlet 152 , and the wet gas is humidified and then discharged along the wet gas outlet 17 .

[0046] During specific implementation, the first time, the glue container 2 is used to add a potting glue with a height of about 10 mm-20 mm into the shell 1 to plug the hole of the membrane tube 14, forming a first glue layer 18; the second time, the glue container 2 is used to add a potting glue with a height of about 30-40 mm into the shell 1 to form a potting glue surface, that is, a second glue layer 19.

[0047] The height refers to the distance between the top surface of the first adhesive layer 18 and the inner wall of the adhesive filling container 2 , and the second adhesive surface is formed on the side of the first adhesive surface facing away from the adhesive filling container 2 .

[0048] By setting the height of the first adhesive layer 18 and the second adhesive layer 19 , it is possible to achieve good hole plugging and adhesive potting effects while also avoiding the use of excessive potting adhesive, which would result in an excessively thick adhesive layer inside the housing 1 and affect moisture circulation.

[0049] In some embodiments, see Figure 4 The glue filling container 2 includes a glue filling cover 21 and a glue inlet pipe 22 provided on the glue filling cover 21;

[0050] In specific implementation, the membrane tube 14 is selected as a fiber membrane yarn, which is made of polymer materials such as polyester, polyamide, polypropylene, etc. through a spinning process. It has a hollow structure or a solid structure. The fiber diameter is usually in the micron to nanometer level and has excellent hydrophilicity.

[0051] One end of the glue inlet pipe 22 extending into the housing 1 is located between two adjacent membrane tubes 14 .

[0052] During implementation, potting caps 21 are installed at both ends of the housing 1. After sealing the first and second openings 11 and 12, potting glue is then added to a depth of approximately 10-20 mm through a glue inlet pipe 22 from bottom to top into the housing 1 to plug the holes. The potting glue is then used to seal both ends of the membrane tube 14. After the glue solidifies, a first glue layer 18 is formed. The provision of glue inlet pipe 22 limits the flow rate of the potting glue, allowing it to flow slowly into the housing 1, thereby allowing for more precise control of the height of the first glue layer 18.

[0053] In some embodiments, the length of the glue inlet tube 22 extending into one side of the housing 1 is greater than 10 mm and less than 40 mm.

[0054] In practice, the height of the first glue pouring is approximately 10 mm to 20 mm, so the length of the glue inlet pipe 22 must be at least greater than 10 mm. Specifically, the length of the glue inlet pipe 22 entering the housing 1 can be set to be greater than the height of the first glue layer 18. After the first glue layer 18 is formed, the end of the glue inlet pipe 22 extending into the housing 1 is open, facilitating the second glue pouring without the need for drilling or other operations, further simplifying the process and reducing the difficulty of the process.

[0055] In some embodiments, the glue inlet pipe 22 is threadedly connected to the glue filling cover 21. Specifically, a thread groove is provided on the glue filling cover 21, and a thread matching the thread groove is provided on the outer wall of the glue inlet pipe 22.

[0056] In specific implementation, before glue filling, the glue filling cover 21 is first fixedly installed on the two ends of the shell 1, and then the glue inlet pipe 22 is threadedly connected to the glue filling cover 21. After fixing, glue filling is performed to make the glue inlet pipe 22 detachable.

[0057] After the glue filling is completed, the glue inlet pipe 22 is rotated out of the glue filling cover 21 so that the glue inlet pipe 22 is separated from the glue layer first, and then the glue filling cover 21 is removed to reduce the difficulty of disassembling the glue filling container 2.

[0058] In some embodiments, a sealing tape 23 is provided at the connection between the glue inlet pipe 22 and the glue filling cover 21 .

[0059] In specific implementation, the sealing tape 23 is provided to seal the gap between the glue inlet pipe 22 and the glue filling cover 21, preventing the glue from leaking along the gap and avoiding resource waste. The fixing method of the sealing tape 23 is not specifically limited in the embodiment of the present application.

[0060] In some embodiments, the sealing tape 23 is selected as a raw tape, namely polytetrafluoroethylene, which is non-toxic, odorless, has excellent sealing, insulation and corrosion resistance, and is more suitable for the glue filling device of the fuel cell membrane humidifier.

[0061] In some embodiments, the glue inlet tube 22 is cylindrical in shape.

[0062] In specific implementation, since the viscosity of the potting glue is relatively high, providing a cylindrical glue inlet pipe 22 is more conducive to the flow of glue, thereby accelerating the glue pouring rate.

[0063] In some embodiments, a separation layer 24 is provided on the side of the glue potting cover 21 facing the film tube 14 .

[0064] In specific implementation, the separation layer 24 is provided to separate the glue filling cover 21 from the glue layer to prevent the glue filling cover 21 from adhering to the glue layer, so as to facilitate the separation of the glue filling container 2 from the shell 1 and improve the disassembly efficiency.

[0065] In some embodiments, the separator 24 is made of silicone, which is soft and can avoid damaging the adhesive layer.

[0066] In some embodiments, a cavity 211 is formed on the side of the glue-potting cover 21 facing the membrane tube 14 , the separation layer 24 is disposed on the cavity wall, and the distance between the end of the membrane tube 14 and the separation layer 24 is 2 mm-5 mm.

[0067] In a specific implementation, by providing the cavity 211 , the end of the membrane tube 14 can be prevented from abutting against the separation layer 24 , thereby preventing the membrane tube 14 from bending and affecting ventilation, and keeping the membrane tube 14 vertical.

[0068] By setting the distance between the end of the membrane tube 14 and the separation layer 24, the distance between the membrane tube 14 and the separation layer 24 is prevented from being too large, resulting in an increase in the height of the first glue layer 18 during the first glue pouring, thereby reducing the amount of potting glue used.

[0069] In some embodiments, the cavity 211 of the glue potting cover 21 is formed in a direction away from the housing 1. The outer surface of the glue potting cover 21 forming the cavity 211 is provided with rounded corners, which makes it easier to separate the glue potting cover 21 from the glue layer and reduces the difficulty of disassembly.

[0070] In some embodiments, see Figure 1 and Figure 2 , a plurality of support frames 13 are provided in the housing 1, and the plurality of support frames 13 are arranged side by side in the housing 1;

[0071] A plurality of the membrane tubes 14 are fixed in each of the support frames 13 , and both ends of the membrane tubes 14 extend out of the support frame 13 .

[0072] During specific implementation, a plurality of membrane tubes 14 are stacked side by side in the support frame 13 , and the support frame 13 is fixedly installed side by side in the shell 1 along the thickness direction of the shell 1 .

[0073] In specific implementation, by providing the support frame 13 and the two ends of the membrane tube 14 extending out of the support frame 13, during the first glue pouring, the ends of the membrane tube 14 extending out of the support frame 13 can be blocked to control the height of the first glue pouring.

[0074] For specific implementation, see Figure 2 The two ends of the membrane tube 14 extend into the glue filling cover 21 respectively, and the first glue layer 18 formed after the first glue filling wraps the two ends of the membrane tube 14 to achieve precise plugging.

[0075] In some embodiments, both sides of the support frame 13 are arc-shaped. Since the membrane tube 14 is also cylindrical, the support frame 13 can fit more closely to the outer wall of the membrane tube 14 , saving space and allowing more membrane tubes 14 to be placed.

[0076] In some embodiments, see Figure 2 The support frame 13 is provided with a plurality of vent holes 131. By providing the vent holes 131, moisture entering through the moisture inlet 16 enters the humidification membrane tube 14 in the housing 1 through the vent holes 131. After the moisture flows and is humidified, it is discharged into the housing 1 through the vent holes 131. This allows the housing to achieve a humidification effect when used as the outer shell of a fuel cell humidifier.

[0077] For specific implementation, see Figure 2 A partition 132 is provided in the housing, and a cavity 133 for moisture flow is formed between the side of the second glue layer 19 facing away from the glue potting cover 21 and the partition 132;

[0078] The vents 131 on the support frame 13 are symmetrically distributed on both sides of the support frame 13, centered around the partition 132. The vents 131 on both sides of the support frame 13 are connected to the moisture inlet 16 and moisture outlet 17 on the housing 1, respectively. Moisture entering through the moisture inlet 16 flows into the cavity 133 on one side of the partition 132, then enters the humidification membrane tube 14 in the support frame 13 through the vents 131. Then, through the vents 131 on the other side of the support frame 13, enters the cavity 133 on the other side of the partition 132, and finally exits through the moisture outlet 17.

[0079] By providing the partition 132, the shell 1 can continue to be used as the shell of the fuel cell membrane humidifier after plugging the holes and filling with glue. The partition 132 and the support frame 13 are provided to control the flow of moisture and achieve a better humidification effect.

[0080] During specific implementation, after the glue is poured for the second time using the glue pouring device, the second glue layer 19 formed seals the two ends of the support frame 13, so that the cavity 133 is formed between the side of the second glue layer 19 facing away from the glue pouring cover 21 and the partition 132, preventing moisture from passing through the cavity 133 to reach the two sides of the membrane tube 14 and entering the membrane tube 14 to mix with the dry gas.

[0081] In summary, the embodiment of the present application provides a glue filling device for a fuel cell membrane humidifier, which includes a shell 1 and a glue filling container 2 provided at both ends of the shell 1. The first opening 11 and the second opening 12 are blocked with the glue filling container 2, and then glue is poured into the shell 1 to perform the hole blocking and glue filling processes. By providing two glue filling containers 2, it is possible to block the holes and fill glue at both ends of the shell 1 without disassembling, thereby simplifying the product assembly process and shortening the process time. Moreover, each glue filling container 2 can fill glue into the shell 1 twice or more, so that the two separate processes of hole blocking and glue filling are merged into one continuous process, which improves the assembly efficiency on the one hand and greatly improves the effectiveness of the hole blocking process on the other hand, thereby preventing the membrane tube hole blocking process from reducing the performance of the fuel cell membrane humidifier.
