Method for processing fuel cell electrode packaging frame

Abstract

This invention discloses a method for processing fuel cell electrode encapsulation frames. The method involves sequential steps including equipment preheating, hot stamping detection, temperature increase and speed adjustment, stabilizing the hot stamping, and component forming. A hot stamping machine is used to heat and stamp the raw material roll, recording and comparing the deformation of the roll until it no longer increases, thus determining a stable hot stamping temperature. This stable temperature is used as the standard for hot stamping, and the raw material roll is continuously hot-stamped to maintain a stable structural shape, preventing warping or other deformation. This ensures that the encapsulation frame assembly processed from the hot-stamped raw material roll can be fully adapted and assembled with fuel cell chips, guaranteeing the electrode assembly effect and structural stability of the fuel cell. It also avoids adverse effects on the structural reliability and assembly strength of the proton exchange membrane fuel cell due to deformation of the encapsulation frame assembly in a high-temperature environment during fuel cell assembly.

Description

Technical Field

[0001] This invention relates to the field of proton exchange membrane fuel cell component manufacturing and processing technology, and in particular to a method for processing fuel cell electrode packaging frames. Background Technology

[0002] A proton exchange membrane fuel cell (PEMFC) is an electrochemical cell whose core working process is the reverse reaction of water electrolysis to produce hydrogen and oxygen. Its working principle is that hydrogen, under the action of a catalyst, decomposes into highly unstable and reactive protons and electrons. The protons pass through the proton exchange membrane to the oxygen side of the cathode, while the electrons travel through an external circuit to the oxygen side, where they react with oxygen to produce water. In other words, during the above reaction, electrons generated from hydrogen oxidation travel through an external circuit to the cathode, thus generating an electric current.

[0003] In the current field of fuel cell production and application, proton exchange membrane fuel cells (PEMFCs) not only have advantages such as high energy conversion efficiency and no environmental pollution, but also have advantages such as normal self-starting at low temperatures, long service life, and wide application range. Currently, the most common applications of PEMFCs in the industry include hydrogen fuel cell buses, logistics vehicles, heavy trucks, passenger cars (sedans, SUVs), and also ships and yachts.

[0004] In conclusion, proton exchange membrane fuel cells are a relatively ideal alternative energy source for general energy in the future.

[0005] The electrode sealing frames of existing proton exchange membrane fuel cells mostly adopt hot melt adhesive technology. Therefore, after the frame is aligned and bonded to the CCM (fuel cell chip), a higher temperature is required to activate the adhesive properties of the hot melt adhesive, so that the frames of the anode and cathode can be bonded more tightly to ensure good sealing and overall stack durability.

[0006] The dimensions and flatness of the sealing frame of the proton exchange membrane fuel cell electrode directly affect the assembly of the fuel cell stack. If the dimensional accuracy of the frame is not up to standard, it may lead to uneven edges of the fuel cell stack, direct contact between bipolar plates causing short circuits, etc. If the sealing frame of the electrode is severely warped, it will bring greater difficulty in gripping and alignment during the fuel cell stack assembly process, which will adversely affect the assembly and production of the corresponding fuel cell.

[0007] Therefore, optimizing the processing of the electrode sealing frame of a proton exchange membrane fuel cell and avoiding adverse effects on the structural assembly of the proton exchange membrane fuel cell due to structural deformation such as warping of the sealing frame is an important technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0008] The purpose of this invention is to provide a method for processing fuel cell electrode packaging frames. This method can optimize the processing effect of the electrode sealing frame of a proton exchange membrane fuel cell and avoid adverse effects on the structural assembly of the proton exchange membrane fuel cell caused by structural deformation such as warping of the sealing frame.

[0009] To address the aforementioned technical problems, this invention provides a method for processing fuel cell electrode packaging frames, employing the medical waste treatment system described above, and including the following steps:

[0010] The equipment is preheated. The raw material roll used to process the fuel cell electrode encapsulation frame is passed through the heating roller of the hot stamping machine, and the hot stamping temperature of the hot stamping machine is set. The initial value of the hot stamping temperature is lower than the activation temperature of the adhesive layer of the fuel cell electrode encapsulation frame. The hot stamping is started after the hot stamping temperature of the hot stamping machine rises to the required operating temperature, and the heating roller continues to run.

[0011] Heat treatment: Maintain stable operation of the heat treatment machine and continuously heat the raw material rolls. During this process, continuously measure and record the deformation of the raw material rolls after heat treatment.

[0012] The heating speed is variable, and the heating temperature of the heating machine is gradually increased based on the deformation parameters of the raw material roll obtained during the heating process. The deformation of the raw material roll is continuously recorded as the heating temperature increases.

[0013] Stable heat treatment: When the deformation of the raw material roll no longer increases, the current heat treatment temperature of the heat treatment machine is taken as the stable operating temperature, and the heat treatment machine is kept at a stable operating temperature to continuously perform heat treatment on the raw material roll.

[0014] In the component forming process, the raw material rolls that have undergone hot stamping are rolled up and arranged into pre-formed rolls. Based on the processing requirements of fuel cell products, the pre-formed rolls are cut and shaped accordingly to obtain the encapsulation frame components.

[0015] Preferably, after stabilizing the hot water material in the above steps, the method further includes the following step:

[0016] After determining the current stable operating temperature, the packaging frame components are first trial-produced based on the raw material rolls treated at the stable operating temperature.

[0017] Preferably, after the step of batch trial production, the method further includes the following step:

[0018] Trial production and testing: If the structure of the packaged frame assembly obtained from the trial production can meet the reliable packaging requirements of the fuel cell electrode, then proceed to the next step of assembly molding.

[0019] If the structure of the prototype encapsulation frame assembly does not meet the reliable encapsulation requirements of the fuel cell electrode, the steps of heating and speed change, stabilizing hot material, and batch trial production are repeated in sequence until the prototype encapsulation frame assembly can meet the reliable encapsulation requirements of the fuel cell electrode, and then the next step of assembly forming is carried out.

[0020] Preferably, before the equipment is preheated, the step further includes:

[0021] The benchmark measurement involves measuring the width of the raw material roll at multiple locations upon acquisition and recording the corresponding width data as a reference for subsequent comparison of the raw material roll deformation.

[0022] Preferably, in the step of hot stamping detection, the deformation of the raw material roll is specifically the width deformation of the raw material roll.

[0023] Compared to the aforementioned background technology, the fuel cell electrode encapsulation frame processing method provided by this invention, in its operation and application, involves sequential steps such as equipment preheating, hot stamping detection, temperature rise and speed adjustment, stabilizing hot stamping, and component forming. The hot stamping machine heats and stamps the raw material roll, continuously recording and comparing the deformation of the raw material roll during the hot stamping process until the deformation no longer increases, thereby determining the stable operating temperature for the hot stamping operation. This stable operating temperature is then used as the standard operating temperature for the hot stamping operation, allowing for stable and continuous hot stamping of the raw material roll. This ensures the structural shape of the raw material roll remains stable, preventing warping or other dimensional or structural deformations. This guarantees that the encapsulation frame assembly processed from the hot-stamped raw material roll can be fully adapted and assembled with membrane structural components such as fuel cell chips, ensuring the electrode assembly effect and structural stability of the fuel cell. It avoids adverse effects on the structural reliability and assembly strength of the proton exchange membrane fuel cell component due to deformation of the encapsulation frame assembly in a high-temperature environment during fuel cell assembly, thereby improving the overall structural reliability and operational stability of the proton exchange membrane fuel cell.

[0024] In another preferred embodiment of the present invention, after the step of stabilizing the hot-pressing material, the method further includes the step of batch trial production. After determining the current stable operating temperature, the packaging frame assembly is trial-produced based on the raw material roll treated at the stable operating temperature. By trial-assembling the packaging frame assemblies produced in the batch of this trial production step, the deformation of the packaging frame assembly made from the raw material roll treated at the current stable operating temperature is determined. After confirming that the raw material roll treated at the current stable operating temperature can meet the assembly requirements of the corresponding packaging frame assembly, the subsequent component forming process is then carried out to achieve stable and continuous production of the packaging frame assembly.

[0031] The core of this invention is to provide a method for processing fuel cell electrode packaging frames. This method can optimize the processing effect of the electrode sealing frame of a proton exchange membrane fuel cell and avoid adverse effects on the structural assembly of the proton exchange membrane fuel cell caused by structural deformation such as warping of the sealing frame.

[0032] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Please refer to Figure 1 .

[0034] In Embodiment 1, the fuel cell electrode packaging frame processing method provided by the present invention includes:

[0035] Step S101: Preheat the equipment.

[0036] The raw material roll used to process the fuel cell electrode encapsulation frame is passed through the heating roller of the hot stamping machine, and the hot stamping temperature of the hot stamping machine is set. The initial value of the hot stamping temperature is lower than the activation temperature of the adhesive layer of the fuel cell electrode encapsulation frame. Once the hot stamping temperature of the hot stamping machine rises to the required operating temperature, the hot stamping is started, and the heating roller continues to run.

[0037] It should be noted that the activation temperature of the adhesive layer is the operating temperature at which the adhesive layer achieves optimal bonding performance. In actual operation, the setting value of the hot stamping machine's heat exchanger should be set with reference to the activation temperature of the adhesive layer of the encapsulation frame under actual operating conditions. Considering the application scenarios in most cases, the activation temperature of the adhesive layer used for encapsulation frame assembly is generally 100℃~120℃. Accordingly, the initial value of the heat exchanger's heat exchanger should be slightly lower than this temperature value to obtain a more stable and suitable heat exchanger heating process and optimize the heat exchanger effect.

[0038] Of course, in practical applications, the activation temperature of the adhesive layer will change depending on the type of adhesive material used in the specific application. Therefore, the initial value of the hot-heating temperature of the hot-heating machine should also be adjusted accordingly.

[0039] Step S102, heat treatment of hot material.

[0040] Maintain stable operation of the hot stamping machine and continuously hot stamp the raw material rolls. During this process, continuously measure and record the deformation of the raw material rolls after hot stamping.

[0041] Step S103, temperature increase and speed adjustment.

[0042] Based on the deformation parameters of the raw material roll obtained during the hot stamping process, the hot stamping temperature of the hot stamping machine is gradually increased, and the deformation of the raw material roll is continuously recorded as the hot stamping temperature increases.

[0043] Step S104: Stabilize the hot material.

[0044] When the deformation of the raw material roll no longer increases, the current hot stamping temperature of the hot stamping machine is taken as the stable operating temperature, and the hot stamping machine is kept at a stable operating temperature to continuously perform hot stamping treatment on the raw material roll.

[0045] Furthermore, in the aforementioned steps, the deformation of the raw material roll specifically refers to the width deformation of the raw material roll. The width of the raw material roll is the axial extension dimension of the raw material roll along its spool. In actual operation, the measurement of this width dimension is relatively convenient, and the data acquisition efficiency is high, which helps to further optimize the efficiency of the corresponding process operations and the overall processing effect.

[0046] Step S105, component forming.

[0047] After the raw material rolls have undergone heat treatment, they are wound up and organized into pre-fabricated rolls. Based on the processing requirements of fuel cell products, the pre-fabricated rolls are cut and shaped accordingly to obtain the encapsulation frame assembly.

[0048] Please refer to Figure 2 .

[0049] In Embodiment 2, the fuel cell electrode packaging frame processing method provided by the present invention includes:

[0050] Step S201: Preheat the equipment.

[0051] The raw material roll used to process the fuel cell electrode encapsulation frame is passed through the heating roller of the hot stamping machine, and the hot stamping temperature of the hot stamping machine is set. The initial value of the hot stamping temperature is lower than the activation temperature of the adhesive layer of the fuel cell electrode encapsulation frame. Once the hot stamping temperature of the hot stamping machine rises to the required operating temperature, the hot stamping is started, and the heating roller continues to run.

[0052] It should be noted that the activation temperature of the adhesive layer is the operating temperature at which the adhesive layer achieves optimal bonding performance. In actual operation, the setting value of the hot stamping machine's heat exchanger should be set with reference to the activation temperature of the adhesive layer of the encapsulation frame under actual operating conditions. Considering the application scenarios in most cases, the activation temperature of the adhesive layer used for encapsulation frame assembly is generally 100℃~120℃. Accordingly, the initial value of the heat exchanger's heat exchanger should be slightly lower than this temperature value to obtain a more stable and suitable heat exchanger heating process and optimize the heat exchanger effect.

[0053] Of course, in practical applications, the activation temperature of the adhesive layer will change depending on the type of adhesive material used in the specific application. Therefore, the initial value of the hot-heating temperature of the hot-heating machine should also be adjusted accordingly.

[0054] Step S202, Hot material inspection.

[0055] Maintain stable operation of the hot stamping machine and continuously hot stamp the raw material rolls. During this process, continuously measure and record the deformation of the raw material rolls after hot stamping.

[0056] Step S203, temperature increase and speed adjustment.

[0057] Based on the deformation parameters of the raw material roll obtained during the hot stamping process, the hot stamping temperature of the hot stamping machine is gradually increased, and the deformation of the raw material roll is continuously recorded as the hot stamping temperature increases.

[0058] Step S204: Stabilize the hot material.

[0059] When the deformation of the raw material roll no longer increases, the current hot stamping temperature of the hot stamping machine is taken as the stable operating temperature, and the hot stamping machine is kept at a stable operating temperature to continuously perform hot stamping treatment on the raw material roll.

[0060] Furthermore, in the aforementioned steps, the deformation of the raw material roll specifically refers to the width deformation of the raw material roll. The width of the raw material roll is the axial extension dimension of the raw material roll along its spool. In actual operation, the measurement of this width dimension is relatively convenient, and the data acquisition efficiency is high, which helps to further optimize the efficiency of the corresponding process operations and the overall processing effect.

[0061] Step S205: Batch trial production.

[0062] After determining the current stable operating temperature, the packaging frame assembly is first trial-produced based on the raw material rolls treated at this stable operating temperature. Generally, this batch trial production process involves small-batch product testing to control the overall cost of the trial production process. Of course, in specific operations, the number of trial-produced products can be increased or decreased according to specific operating conditions to match the corresponding process requirements.

[0063] By performing trial assembly of the packaging frame components produced in batches through this trial production process, the deformation of the packaging frame components made from the raw material rolls after the current stable operating temperature treatment is determined. Once it is confirmed that the raw material rolls after the current stable operating temperature treatment can meet the corresponding packaging frame component assembly requirements, subsequent component forming processes are carried out to achieve stable and continuous production of packaging frame components.

[0064] Step S206, component forming.

[0065] After the raw material rolls have undergone heat treatment, they are wound up and organized into pre-fabricated rolls. Based on the processing requirements of fuel cell products, the pre-fabricated rolls are cut and shaped accordingly to obtain the encapsulation frame assembly.

Once the hot stamping temperature of the hot stamping machine rises to the required operating temperature, the hot stamping is started, and the heating roller continues to run.

[0070] It should be noted that the activation temperature of the adhesive layer is the operating temperature at which the adhesive layer achieves optimal bonding performance. In actual operation, the setting value of the hot stamping machine's heat exchanger should be set with reference to the activation temperature of the adhesive layer of the encapsulation frame under actual operating conditions. Considering the application scenarios in most cases, the activation temperature of the adhesive layer used for encapsulation frame assembly is generally 100℃~120℃. Accordingly, the initial value of the heat exchanger's heat exchanger should be slightly lower than this temperature value to obtain a more stable and suitable heat exchanger heating process and optimize the heat exchanger effect.

[0071] Of course, in practical applications, the activation temperature of the adhesive layer will change depending on the type of adhesive material used in the specific application. Therefore, the initial value of the hot-heating temperature of the hot-heating machine should also be adjusted accordingly.

Once it is confirmed that the raw material rolls after the current stable operating temperature treatment can meet the corresponding packaging frame component assembly requirements, subsequent component forming processes are carried out to achieve stable and continuous production of packaging frame components.

[0082] Step S306: Trial production and testing.
