[0002] Membrane electrode assembly (MEA) is a core component of hydrogen fuel cells.

The alignment of the layers is achieved by controlling the roll speed and tension, ensuring that the opening of the active area on the frame matches the cycle time of the CCM sheet. Improving the yield rate and quality control accuracy of the finished MEAs will significantly reduce manufacturing costs and improve stack performance, making this a pressing technical challenge.

Detailed Implementation

[0031] 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.

[0032] 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.

[0033] In related technologies, the active zone opening of the edge strip is typically rectangular, and its extension direction is parallel to the belt travel direction. During the conveying process of the strip, the active zone opening is aligned with the CCM sheet by controlling tension and belt travel speed.

[0034] The inventors discovered through research that the cross-sectional area of ​​the material strip fluctuates during its transport, causing variations in the tensile strength applied to the strip. In particular, there are significant stress abrupt changes before and after the short side of the active zone opening. On one hand, this causes deformation of the material strip during traction, making it difficult to bond the frame to the CCM sheet. On the other hand, most MEA production processes currently use a support film material strip for transporting the material strip. Subsequent processes involve removing the support film material strip. During the removal process, the lack of support causes deformation of the active zone opening, leading to the tearing off of the upper and lower frames.

[0035] like Figures 1 to 3 As shown, the frame-making equipment 100 of some embodiments of this application includes an unwinding mechanism 110, a roll-cutting mechanism 120, and a winding mechanism 130. The unwinding mechanism 110 is used to unwind the frame composite material strip 310, which includes a backing film strip 311 and a frame strip 312 stacked together. The roll-cutting mechanism 120 is located downstream of the unwinding mechanism 110 and is used to roll-cut the frame strip 312 of the frame composite material strip 310 to form a finished frame material strip 300 with an active area opening 313. The winding mechanism 130 is located downstream of the roll-cutting mechanism 120 and is used to wind up the finished frame material strip 300. The roll-cutting direction of the roll-cutting mechanism 120 is angled to the travel direction of the frame composite material strip 310 so that the extension direction of the active area opening 313 is angled.

[0036] Specifically, the frame composite material strip 310 is conveyed along direction X, the active area opening 313 is a rectangular opening, the length direction of the active area opening 313 extends along direction P, and the angle between direction P and direction X is α, that is, the angle between the rolling direction of the rolling mechanism 120 and the conveying direction of the frame composite material strip 310 is α, which satisfies 0 < α < 90°.

[0037] In the frame-making equipment 100 of this application embodiment, since the rolling direction of the roller cutting mechanism 120 is set at an angle to the conveying direction of the frame composite material strip 310, the extension direction of the active area opening 313 is set at an angle, thereby alleviating the phenomenon of uneven tension caused by the change of the material strip cross section during the conveying process, thereby reducing the deformation probability of the active area opening 313, improving the finished product qualification rate and quality control accuracy of the frame finished material strip 300.

[0038] In some embodiments of this application, the unwinding mechanism 110 includes a bottom film unwinding mechanism 111, a raw material unwinding mechanism 112, and a composite roller assembly 113. The bottom film unwinding mechanism 111 is used to unwind the bottom film strip 311, the raw material unwinding mechanism 112 is used to unwind the edge strip 312, and the composite roller assembly 113 is used to press the bottom film strip 311 and the edge strip 312 together to form the edge composite strip 310.

[0039] The composite roller assembly 113 is located downstream of the bottom film unwinding mechanism 111 and the raw material unwinding mechanism 112. It is used to receive the bottom film strip 311 and the edge strip 312. After being pressed by the composite roller, the edge composite strip 310 is formed. The edge composite strip 310 includes the bottom film strip 311 and the edge strip 312 stacked together. The bottom film strip 311 plays a supporting role in the material conveying and roller cutting process.

[0040] In some embodiments of this application, the frame-making equipment 100 further includes a waste discharge mechanism 140, which is located downstream of the roll cutting mechanism 120 and is used to discharge the waste material 314 generated during the roll cutting process.

[0041] During the process of forming the active zone opening 313 by the roll cutting mechanism 120, the part of the edge strip 312 corresponding to the active zone opening 313 is cut off to form waste material 314.

[0042] The waste removal mechanism 140 includes a tape unwinding mechanism 141, a waste removal roller pair 142, and a waste material winding mechanism 143. The waste removal roller pair 142 is located downstream of the roll cutting mechanism 120 and is used to receive the edge finished material tape 300 with waste material 314. The edge finished material tape 300 passes between a pair of waste removal rollers 142. The tape unwinding mechanism 141 unwinds the tape, and the tape also passes between a pair of waste removal rollers 142 and is located on the side close to the edge material tape 312. After the waste material 314 is removed, it is wound up by the waste material winding mechanism 143.

[0043] The waste removal mechanism 140 can remove the waste material 314 generated during the roll cutting process, maintaining a clean environment on the production line.

[0044] In some embodiments of this application, the frame-making equipment 100 further includes a traction mechanism 150, which is located downstream of the roll cutting mechanism 120 and is used to drive the finished frame material strip 300 to move forward.

[0045] The traction mechanism 150 consists of a pair of power rollers. By setting the traction mechanism 150, the edge finished material belt 300 can be driven to move forward.

[0046] like Figures 4 to 9 As shown, some embodiments of the MEA production equipment 200 of this application include a lower frame providing mechanism 210, a CCM providing mechanism 220, a first bonding mechanism 230, an upper frame providing mechanism 240, and a second bonding mechanism 250. The lower frame providing mechanism 210 is used to provide a lower frame material strip 412, the extension direction of the active area opening 413 of the lower frame material strip 412 is set at an angle; the CCM providing mechanism 220 is used to provide a CCM sheet 422; the first bonding mechanism 230 is used to bond the CCM sheet 422 to the active area opening 413 of the lower frame material strip 412; the upper frame providing mechanism 240 is used to provide an upper frame sheet 432, the extension direction of the active area opening 433 of the upper frame sheet 432 is set at an angle; the second bonding mechanism 250 is used to bond the upper frame sheet 432 to the lower frame material strip 412 to form an MEA composite material strip 450. The conveying direction of the CCM sheet 422 is set at an angle to the conveying direction of the lower frame strip 412.

[0047] In the MEA production equipment 200 of this application embodiment, the extension direction of the active area opening 413 of the lower frame strip 412 is set at an angle, the extension direction of the active area opening 433 of the upper frame sheet 432 is set at an angle, and the conveying direction of the CCM sheet 422 is set at an angle to the conveying direction of the lower frame strip 412. This enables the CCM sheet bonding process and the upper and lower frame bonding process to be performed on the frame strip with the active area opening extending at an angle. This can alleviate the phenomenon of uneven tension caused by the change of the strip cross section during the belt feeding process, thereby reducing the deformation probability of the active area opening and improving the finished product qualification rate and quality control accuracy of the MEA composite strip 450.

[0048] In some embodiments of this application, the lower frame providing mechanism 210 includes a lower frame unwinding mechanism 211 and a first backing film winding mechanism 212. The lower frame unwinding mechanism 211 is used to unwind the lower frame composite material strip 410, which includes a backing film strip 411 and a lower frame strip 412 stacked together. The first backing film winding mechanism 212 is located downstream of the second bonding mechanism 250 and is used to wind up the backing film strip 411.

[0049] The bottom film strip 411 of the lower frame composite strip 410 plays a supporting role in both the CCM sheet lamination and the upper and lower frame lamination processes.

[0050] In some embodiments of this application, the upper frame providing mechanism 240 includes an upper frame unwinding mechanism 241 and a second bottom film winding mechanism 242. The upper frame unwinding mechanism 241 is used to unwind the upper frame composite material strip 430, which includes a bottom film strip 431 and an upper frame sheet 432 stacked together. The second bottom film winding mechanism 242 is located downstream of the second bonding mechanism 250 and is used to wind up the bottom film strip 431.

[0051] After the second bonding mechanism 250 completes the bonding of the upper and lower edges, the second bottom film winding mechanism 242 winds up the bottom film strip 431, and the MEA composite strip 450 continues to move forward.

[0052] In some embodiments of this application, both the lower frame composite strip 410 and the upper frame composite strip 430 are prepared using the frame-making equipment 100 of this application. Since the upper and lower frames have opposite shapes, the roll-cutting mechanisms 120 of their respective frame-making equipment 100 have different structures. To eliminate length errors, the upper frame composite strip 430 needs to be cut into upper frame sheet material 432 and supplied in sheet form.

[0053] In some embodiments of this application, the MEA production equipment 200 further includes a film-peeling mechanism 260, which is located downstream of the second bonding mechanism 250 and is used to peel off the bottom film strip.

[0054] The bottom support film strip here includes a bottom support film strip 411 from the lower frame composite strip 410 located at the bottom layer and a bottom support film strip 431 from the upper frame composite strip 430 on the surface.

[0055] Taking the lower frame as an example, since the extension direction of the active area opening 413 of the lower frame material strip 412 is set at an angle to the conveying direction of the lower frame material strip 412, during the process of the film tearing mechanism 260 peeling off the bottom film material strip 411, the corner edge is easier to start than the flat edge, thereby reducing the probability of deformation of the active area opening 413, simplifying the film tearing process, and ensuring the film tearing quality.

[0056] In some embodiments of this application, the CCM providing mechanism 220 includes a CCM unwinding mechanism 221 and a third backing film winding mechanism 222. The CCM unwinding mechanism 221 is used to unwind the CCM composite material strip 420, which includes a backing film strip 421 and a CCM sheet 422 stacked together. The third backing film winding mechanism 222 is located downstream of the first bonding mechanism 230 and is used to wind up the backing film strip 421.

[0057] After the first bonding mechanism 230 completes the bonding of the CCM sheet 422 and the lower frame strip 412, the third bottom film winding mechanism 222 winds up the bottom film strip 421, and the lower frame strip 412 of the bonded CCM sheet 422 continues to move forward.

[0058] In some embodiments of this application, the MEA production equipment 200 further includes a carbon paper application mechanism 270, located downstream of the second bonding mechanism 250, for applying carbon paper 440 to each MEA sheet 400 from both sides of the MEA composite strip 450.

[0059] In the carbon paper bonding process, robot vision is used for alignment and coordination. The active area opening 313 and the MEA composite material strip 450 are set at an angle. The carbon paper 440 only needs to be tilted at the same angle to complete the bonding.

[0060] In some embodiments of this application, the MEA production equipment 200 further includes a die-cutting mechanism 280, located downstream of the second bonding mechanism 250, for cutting the MEA composite strip 450 to form MEA sheet 400; wherein the extension direction of the die-cutting profile of the die-cutting mechanism 280 is set at an angle to the conveying direction of the MEA composite strip 450.

[0061] The die-cutting die of the die-cutting mechanism 280 is made at a certain angle so that the die-cutting contour is the same as the contour of the MEA sheet 400, thus producing qualified MEA sheet 400.

[0062] MEA production equipment 200 also includes a finished product station, located downstream of the die-cutting mechanism 280, for receiving MEA sheet material 400.

[0063] like Figures 1 to 3 As shown, the working principle of the frame-making device 100 in this embodiment is as follows:

[0064] The bottom film unwinding mechanism 111 unwinds the bottom film strip 311, and the raw material unwinding mechanism 112 unwinds the edge strip 312. The bottom film strip 311 and the edge strip 312 enter the composite roller assembly 113 and are pressed by the composite roller to form the edge composite strip 310.

[0065] The frame composite material strip 310 is conveyed along direction X and sequentially passes through the roll cutting mechanism 120, the waste discharge mechanism 140, and the traction mechanism 150. The roll cutting mechanism 120 rolls along direction P. The roll cutting direction of the roll cutting mechanism 120 is set at an angle α with the belt walking direction (i.e., direction X) of the frame composite material strip 310, so as to form an inclined extended active area opening 313 by roll cutting. The finished frame material strip 300 passes through the waste discharge mechanism 140 to remove waste material 314, and continues to move under the drive of the traction mechanism 150 and enters the winding mechanism 130 for winding.

[0066] like Figures 4 to 9 As shown, the working principle of the MEA production equipment 200 in this embodiment is as follows:

[0067] The lower frame unwinding mechanism 211 unwinds the lower frame composite material strip 410, and the CCM unwinding mechanism 221 unwinds the CCM composite material strip 420. The lower frame composite material strip 410 and the CCM composite material strip 420 enter the first bonding mechanism 230 together, and the CCM sheet 422 is bonded one by one into the active area opening 413 of the lower frame material strip 412. The travel direction of the CCM composite material strip 420 is set at an angle to the travel direction of the lower frame composite material strip 410 to adapt to the inclined extension of the active area opening 413.

[0068] Downstream of the first bonding mechanism 230, the third backing film winding mechanism 222 winds up the backing film strip 421 of the CCM composite strip 420, and the lower frame composite strip 410 with the CCM sheet 422 bonded to it continues to move.

[0069] The upper frame unwinding mechanism 241 unwinds the upper frame composite material strip 430. The upper frame material strip 430 is cut to form an upper frame sheet 432. The lower frame composite material strip 410 with CCM sheet 422 attached and the upper frame composite material strip 430 enter the second bonding mechanism 250 together, and the upper frame sheet 432 is bonded to the lower frame material strip 412 one by one. The active area opening 433 of the upper frame sheet 432 is aligned with the CCM sheet 422. The belt travel directions of the upper frame composite material strip 430 and the lower frame composite material strip 410 are parallel.

[0070] Downstream of the second bonding mechanism 250, there is a film-tearing mechanism 260 that simultaneously peels the bottom film strip 411 of the lower frame composite strip 410 and the bottom film strip 431 of the upper frame composite strip 430 from both sides, and then enters the first bottom film winding mechanism 212 and the second bottom film winding mechanism 242 for winding.

[0071] The MEA composite strip 450 continues to travel and passes through the carbon paper application mechanism 270 and the die-cutting mechanism 280 in sequence. When passing through the carbon paper application mechanism 270, carbon paper 440 is applied to both sides of each MEA sheet 400. When passing through the die-cutting mechanism 280, it is punched to form a single MEA sheet 400. The die-cutting profile is set at an angle to the travel direction of the MEA composite strip 450 to accommodate the inclined extended active area opening.

[0072] The active area opening of the frame material strip corresponding to the frame making equipment 100 and MEA production equipment 200 in this application embodiment extends at an angle relative to the conveyor belt direction, which can alleviate the phenomenon of uneven tension caused by the change of the material strip cross section during the conveyor belt process, thereby reducing the deformation probability of the active area opening and improving the finished product qualification rate and quality control accuracy of the frame finished material strip and MEA sheet.

[0073] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0074] 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.
