[0002] Membrane electrode assembly (MEA) is a core component of hydrogen fuel cells. The manufacturing process and product quality of MEA determine the upper limit of stack performance, lifespan, and cost. High-performance, low-cost, and long-life MEAs are of great significance to accelerating the commercialization of hydrogen fuel cells.
[0003] In the manufacturing process of membrane electrode assemblies (MEAs), the upper frame, catalyst-coated proton exchange membrane (CCM), and lower frame need to be laminated and hot-pressed to form the finished MEA strip. Currently, the mainstream double-layer frame strip is prepared using a flatbed die-cutting process, which not only occupies a large area of equipment but also consumes a lot of energy. During the flatbed cutting process, the strip is repeatedly started and stopped, resulting in excessive tension fluctuations, which adversely affects the quality of the frame strip. Utility Model Content

The mask roll cutting mechanism is used to cut the mask material strip to form a mask sheet covering the opening of the first active area. The mask winding mechanism is used to wind up the mask waste material strip.
[0007] Optionally, the fuel cell double-layer frame preparation equipment further includes: a first protective film winding mechanism, located downstream of the first frame roll cutting mechanism, for winding the first protective film strip on the surface of the first frame strip.
[0008] Optionally, the fuel cell double-layer frame preparation equipment further includes a first waste discharge mechanism, comprising: a first tape unwinding mechanism, a first adhesive roller, and a first tape winding mechanism. The first tape unwinding mechanism is used to unwind the first tape, the first adhesive roller is disposed downstream of the first frame roll cutting mechanism, and the first tape winding mechanism is used to wind the first tape with waste material adhering to it.

The first frame roll cutting mechanism rolls the first frame strip to form a first active region opening. After pressing the first frame strip with the first active region opening and the second frame strip together, the second frame roll cutting mechanism rolls the second frame strip to form a second active region opening, thereby forming a double-layer frame strip. Since both the first and second frame strips are produced using a roll cutting process, compared to a flatbed die-cutting process, it has the advantage of reducing strip tension fluctuations, thereby reducing the quality fluctuations of the finished double-layer frame strip and improving the production quality of the finished double-layer frame strip.

Detailed Implementation
[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0024] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0025] like Figure 1 , Figure 2 and Figure 3 As shown, the fuel cell double-layer frame fabrication apparatus 100 of some embodiments of this application includes a first frame unwinding mechanism 111, a first frame rolling cutting mechanism 112, a second frame unwinding mechanism 121, a second frame rolling cutting mechanism 122, and a pressing mechanism 130. The first frame unwinding mechanism 111 is used to unwind the first frame material strip 210. The first frame rolling cutting mechanism 112 is used to cut a first active region opening 211 on the first frame material strip 210; the second frame unwinding mechanism 121 is used to unwind the second frame material strip 220; the pressing mechanism 130 is used to press and bond the stacked first frame material strip 210 and the second frame material strip 220 with the first active region opening 211; the second frame rolling cutting mechanism 122 is disposed downstream of the pressing mechanism 130 and is used to cut a second active region opening 221 on the second frame material strip 220.
[0026] The opening regions of the first active region opening 211 and the second active region opening 221 are different. For example, the projection of the opening region of the second active region opening 221 falls into the opening region of the first active region opening 211. The fuel cell double-layer frame preparation equipment 100 can be used to prepare the upper frame material strip or the lower frame material strip, which can be used as raw materials for the next process of preparing the membrane electrode. The first active region opening 211 and the second active region opening 221 correspond to the catalyst coating region of the membrane electrode CCM sheet.
[0027] The fuel cell double-layer frame fabrication equipment 100 of this application embodiment includes a first frame roll cutting mechanism 112, a second frame roll cutting mechanism 122, and a pressing mechanism 130. The first frame roll cutting mechanism 112 rolls the first frame strip 210 to form a first active area opening 211. After pressing the first frame strip 210 with the first active area opening 211 and the second frame strip 220 with the first active area opening 211 together, the second frame roll cutting mechanism 122 rolls the second frame strip 220 to form a second active area opening 221, thereby forming a double-layer frame strip. Since both the first frame strip 210 and the second frame strip 220 adopt the roll cutting process, compared with the flat die cutting process, it has the advantage of reducing the tension fluctuation of the strip, thereby reducing the quality fluctuation of the finished double-layer frame strip and improving the production quality of the finished double-layer frame strip.
[0028] In some embodiments of this application, the fuel cell double-layer frame fabrication equipment 100 further includes a bottom film mask providing mechanism 140, which is located upstream of the first frame roll cutting mechanism 112. It includes a bottom film mask unwinding mechanism 141, a mask roll cutting mechanism 142, and a mask winding mechanism 143. The bottom film mask unwinding mechanism 141 is used to unwind the bottom film mask material strip 230. The bottom film mask material strip 230 includes a bottom film material strip 231 and a mask material strip 232 stacked together. The mask roll cutting mechanism 142 is used to cut the mask material strip 232 to form a mask sheet 233 covering the opening 211 of the first active area. The mask winding mechanism 143 is used to wind up the mask waste material strip.
[0029] The mask sheet 233 covers the opening 211 of the first active area, exposing the frame structure of the edge of the opening 211 of the first active area; the mask waste strip is the strip after the mask sheet 233 has been cut off; the mask roll cutting mechanism 142 is located upstream of the first frame roll cutting mechanism 112. After the bottom film mask strip 230 is rolled by the mask roll cutting mechanism 142, it forms a stacked bottom film strip 231 and mask sheet 233, which enter the first frame roll cutting mechanism 112 together with the first frame strip 210. The mask sheet 233 covers the opening 211 of the first active area; the mask winding mechanism 143 is located downstream of the mask roll cutting mechanism 142. The mask waste strip is torn off from the surface of the bottom film strip 231 before the bottom film strip 231 enters the first frame roll cutting mechanism 112 and is wound up by the mask winding mechanism 143.
[0030] With this configuration, the first frame strip 210 can be rolled using the bottom film strip 231 as the base film, and a mask sheet 233 covering the opening 211 of the first active area is sandwiched between the bottom film strip 231 and the first frame strip 210.
[0031] In some embodiments of this application, the fuel cell double-layer frame preparation equipment 100 further includes a first protective film winding mechanism 113, which is located downstream of the first frame roll cutting mechanism 112 and is used to wind up the first protective film strip 212 on the surface of the first frame strip 210.
[0032] The surface of the first frame unwinding mechanism 111 unwinds the first frame material strip 210, which is covered with a first protective film material strip 212. After the first active area opening 211 is formed by roll cutting, the first protective film material strip 212 needs to be removed from the first frame material strip 210 to facilitate the pressing of the first frame material strip 210 and the second frame material strip 220.
[0033] In some embodiments of this application, the fuel cell double-layer frame preparation equipment 100 further includes a first waste discharge mechanism 114, which includes a first tape unwinding mechanism 1141, a first adhesive roller 1142, and a first tape winding mechanism 1143. The first tape unwinding mechanism 1141 is used to unwind the first tape 240, the first adhesive roller 1142 is disposed downstream of the first frame roll cutting mechanism 112, and the first tape winding mechanism 1143 is used to wind up the first tape 240 with waste material adhering to it.
[0034] Based on the implementation of "the surface of the first frame strip 210 is covered with the first protective film strip 212", the waste generated at the first frame roller cutting mechanism 112 refers to the double-layer film waste of the first frame strip 210 and the first protective film strip 212 corresponding to the shape of the first active area opening 211. The first protective film winding mechanism 113 is located downstream of the first adhesive roller 1142, that is, the waste is discharged first and then the first protective film strip 212 is removed.
[0035] This configuration allows for the removal of waste material generated during the frame roll cutting process, facilitating the pressing of the first frame strip 210 and the second frame strip 220 in the next process.
[0036] The second frame unwinding mechanism 121 and the first roll cutting mechanism 112 are both located upstream of the pressing mechanism 130. The second frame material strip 220 unwound by the second frame unwinding mechanism 121, together with the stacked bottom film material strip 231, mask sheet material 233 and the first frame material strip 210 with the first active area opening 211, enter the pressing mechanism 130.
[0037] In some embodiments of this application, the pressing mechanism 130 is a pair of hot pressing rollers, which use a hot pressing composite process to hot press the first frame strip 210 and the second frame strip 220 into one piece; in other embodiments, one of the rollers may be a hot roller, or both rollers may be pressure rollers, with an external heating device provided.
[0038] In some embodiments of this application, two first border roll cutting mechanisms 112 are provided.
[0039] The first specification roll cutting mechanism 1121 and the second specification roll cutting mechanism 1122 are arranged side by side. The corresponding roll cutting mechanism is activated according to the specific frame size specifications to be produced, while the other roll cutting mechanism is stopped. For example, one of the first specification roll cutting mechanism 1121 and the second specification roll cutting mechanism 1122 corresponds to the upper frame material strip, and the other roll cutting mechanism corresponds to the lower frame material strip.
[0040] In some other embodiments of this application, two second border roll cutting mechanisms 122 are provided.
[0041] The third-specification roll cutting mechanism and the fourth-specification roll cutting mechanism (not shown in the diagram) are set up side by side. The corresponding roll cutting mechanism is activated according to the specific border size specifications to be produced, while the other roll cutting mechanism is stopped. One of the third-specification roll cutting mechanisms and the fourth-specification roll cutting mechanism corresponds to the upper border strip, and the other roll cutting mechanism corresponds to the lower border strip.
[0042] In some embodiments of this application, the fuel cell double-layer frame preparation equipment 100 further includes a second waste discharge mechanism 123, which includes a second tape unwinding mechanism 1231, a second adhesive roller 1232, and a second tape winding mechanism 1233. The second tape unwinding mechanism 1231 is used to unwind the second tape 250, the second adhesive roller 1232 is disposed downstream of the second frame roll cutting mechanism 122, and the second tape winding mechanism 1233 is used to wind up the second tape 250 with waste material adhering to it.
[0043] The second waste removal mechanism 123 removes the waste generated at the second frame roller cutting mechanism 122 by the second adhesive roller 1232. Its working principle is similar to that of the first waste removal mechanism 114, and will not be described in detail here.
[0044] It is understood that the surface of the second frame strip 220 unwound by the second frame unwinding mechanism 121 is covered with a second protective film strip 222. The waste generated at the second frame roll cutting mechanism 122 refers to the double-layer film waste of the second frame strip 220 and the second protective film strip 222, which correspond to the shape of the second active area opening 221.
[0045] This configuration allows for the removal of waste material generated during the edge rolling process, thereby forming a double-layer edge finished material strip 200.
[0046] The fuel cell double-layer frame fabrication equipment 100 also includes a first drive roller mechanism 151, a second drive roller mechanism 152 and a third drive roller mechanism 153.
[0047] The first drive roller mechanism 151 is disposed between the mask roller cutting mechanism 142 and the first frame roller cutting mechanism 112, and is used to drive the stacked bottom film strip 231, mask sheet 233, uncut first frame strip 210 and surface first protective film strip 212 to move forward; the second drive roller mechanism 152 is disposed downstream of the first adhesive roller 1142, and is used to drive the stacked bottom film strip 231, mask sheet 233, first frame strip 210 with first active area opening 211 and surface first protective film strip 212 to move forward; the third drive roller mechanism 153 is disposed downstream of the second adhesive roller 1232, and is used to drive the double-layer frame finished strip 200 to move forward, the double-layer frame finished strip 200 including the stacked bottom film strip 231, mask sheet 233, first frame strip 210 with first active area opening 211, second frame strip 220 with second active area opening 221 and second protective film strip 222.
[0048] In some embodiments of this application, the fuel cell double-layer frame preparation equipment 100 further includes a finished product visual inspection mechanism 160, which is located downstream of the second frame roll cutting mechanism 122.
[0049] The finished product visual inspection mechanism 160 includes a CCD camera, backlight source, adjustment bracket, etc., and uses high-speed flying photography to inspect the roll cutting dimensions of the double-layer frame finished material strip 200.
[0050] The finished product visual inspection mechanism 160 can detect the position of the second active area opening 221 or the first active area opening 211, thereby providing reference data for the cycle time of the next process. It can also detect whether the roll cutting quality is qualified by contour comparison.
[0051] The fuel cell double-layer frame preparation equipment 100 is also equipped with a visual inspection mechanism on the feeding side of the pressing mechanism 130 and the feeding side of the second frame rolling mechanism 122, respectively, to provide reference data for the pressing cycle of the pressing mechanism 130 and the rolling cycle of the second frame rolling mechanism 122, so that the positions of the first active area opening 211 and the second active area opening 221 correspond.
[0052] In some embodiments of this application, the fuel cell double-layer frame preparation apparatus 100 further includes a labeling mechanism 170, which is disposed downstream of the second frame roll cutting mechanism 122.
[0053] By setting up a labeling mechanism 170, it is possible to mark the double-bordered finished strip 200 and mark unqualified segments according to the inspection results of the finished product visual inspection mechanism 160.
[0054] In some embodiments of this application, the fuel cell double-layer frame fabrication equipment 100 further includes a finished product winding mechanism 180 for winding the finished double-layer frame material strip 200.
[0055] The double-framed finished material strip 200 includes a bottom film strip 231 stacked together, a mask sheet 233 covering the first active area opening 211, a first frame strip 210 with the first active area opening 211, a second frame strip 220 with the second active area opening 221, and a second protective film strip 222.
[0056] The finished product winding mechanism 180 can wind up the double-sided edge finished material strip 200 to provide the finished material strip for the next process.
[0057] Some embodiments of the membrane electrode manufacturing equipment of this application include a fuel cell bilayer frame fabrication equipment 100.
[0058] Due to the characteristics of the fuel cell double-layer frame fabrication equipment 100, the production quality of the MEA finished material strip of the membrane electrode production equipment is also improved.
[0059] The working principle of the fuel cell double-layer frame fabrication device 100 in this embodiment is as follows:
[0060] The bottom mask unwinding mechanism 141 unwinds the bottom mask material strip 230, which is then cut by the mask roll cutting mechanism 142 to form a mask sheet material 233. The mask waste material strip is then wound up by the mask winding mechanism 143.
[0061] The first frame unwinding mechanism 111 unwinds the first frame material strip 210. The bottom film material strip 231, carrying the mask sheet material 233, is stacked with the first frame material strip 210 and enters the first frame roller cutting mechanism 112 together. The first active area opening 211 is cut out on the first frame material strip 210. The mask sheet material 233 covers the first active area opening 211. The first waste removal mechanism 114 removes the double-layer film waste of the first protective film material strip 212 and the first frame material strip 210 at the first active area opening 211. Then, the first protective film winding mechanism 113 winds up the first protective film material strip 212.
[0062] The second frame unwinding mechanism 121 unwinds the second frame material strip 220, which, together with the stacked bottom film material strip 231, mask sheet material 233, and first frame material strip 210 with the first active area opening 211, enters the pressing mechanism 130. After hot pressing, the first frame material strip 210 and the second frame material strip 220 are combined into one. Then, they pass through the second frame roller cutting mechanism 122 and the second waste removal mechanism 123 in sequence. The second active area opening 221 is cut out on the second frame material strip 220, and the waste material of the second protective film material strip 222 and the second frame material strip 220 at the second active area opening 221 is removed, forming a double-layer frame finished material strip 200. The bottom film material strip 231 and the second protective film material strip 222 play a protective role from both sides of the material strip.
[0063] After passing through the finished product visual inspection mechanism 160 and the labeling mechanism 170, the double-layer framed finished material strip 200 is wound up by the finished product winding mechanism 180.
[0064] The fuel cell double-layer frame preparation equipment 100 of this application embodiment has a reasonable overall layout and high space utilization. The machine does not stop during the process of cutting the opening of the active area of the double-layer frame. When switching between the upper frame material strip and the lower frame material strip, automatic production can be achieved by changing the roller cutting mechanism, avoiding manual replacement of the die. The material strip has a small fluctuation range and has high production quality.
[0065] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.
[0066] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
