Abstract

The utility model relates to a CCM transfer apparatus, including catalyst transfer means, proton membrane feedway, positive pole feedway and negative pole feedway. Under normal working conditions, the proton exchange membrane, the anode transfer printing membrane and the cathode transfer printing membrane in the transfer printing channel are rolled by the first working roller and the second working roller. Because the anode catalyst layer on the anode transfer film and the cathode catalyst layer on the cathode transfer film are coated intermittently, the anode catalyst layer and the cathode catalyst layer can be completely transferred to the proton exchange membrane. When the alignment of the anode catalyst layer and the cathode catalyst layer is deviated, the roll pressing of the proton exchange membrane, the anode transfer film and the cathode transfer film can be released by increasing the distance between the first working roll and the second working roll. At this time, the transport speeds of the cathode transfer film and the cathode transfer film are adjusted, so that the anode catalyst layer and the cathode catalyst layer can be aligned again. As can be seen, the CCM transfer apparatus described above can reduce material waste.

CCM transfer apparatus

Technical Field

The utility model relates to a fuel cell technical field, in particular to CCM transfer apparatus.

Background

CCM (catalyst coated membrane, catalyst/proton exchange membrane assembly) is a core element of a fuel cell, and is composed of a proton exchange membrane and positive and negative catalyst layers attached to both sides of the proton exchange membrane. The preparation process of CCM is generally divided into two processes, one is to directly coat the catalyst slurry on two sides of the proton exchange membrane, and the other is to coat the catalyst on a transfer printing membrane, dry and transfer the catalyst to two sides of the proton exchange membrane by means of transfer printing. Because direct coating has problems such as swelling, which can affect precision, the CCM is generally prepared by transfer printing in the art.

In order to produce a CCM that is compatible with subsequent processing, the catalyst needs to be intermittently transferred during the transfer process, i.e., the catalyst layer on the surface of the proton exchange membrane is discontinuous after transfer. At present, the process for realizing intermittent transfer mainly comprises concave roller transfer and lifting roller transfer. The transfer printing of the concave roller is to make the local part of the transfer printing roller into a concave surface, and the transfer printing can not be realized due to no pressure at the concave surface, so that a gap is formed; when the transfer roller is lifted to the non-transfer area of the proton exchange membrane, the transfer roller is lifted so as not to transfer the non-transfer area to form a gap.

However, the catalyst coated in advance on the transfer film is continuous regardless of whether the transfer is the gravure transfer or the transfer is the gravure transfer. After transfer, only a portion of the catalyst is transferred to the surface of the proton exchange membrane, and more catalyst remains on the transfer membrane. Therefore, the existing transfer printing process can cause great waste of materials.

SUMMERY OF THE UTILITY MODEL

In view of this, there is a need to provide a CCM transfer apparatus capable of significantly reducing material waste in view of the above problems.

A CCM transfer apparatus comprising:

the catalyst transfer printing device comprises a first working roller and a second working roller, wherein the first working roller and the second working roller are arranged oppositely to form a transfer printing channel for a proton exchange membrane, an anode transfer printing film and a cathode transfer printing film to pass through, and the distance between the first working roller and the second working roller is adjustable;

proton membrane supply means for supplying said proton exchange membrane;

the anode feeding device is used for providing the anode transfer printing film, and the surface of the anode transfer printing film is intermittently coated with an anode catalyst layer; and

the cathode feeding device is used for providing the cathode transfer printing film, and the surface of the cathode transfer printing film is intermittently coated with a cathode catalyst layer;

the first working roll and the second working roll can roll the proton exchange membrane, the anode transfer film and the cathode transfer film in the transfer printing channel so as to transfer the anode catalyst layer and the cathode catalyst layer to two sides of the proton exchange membrane respectively and obtain a CCM material belt, and the cathode transfer film can independently move in the transfer printing channel along with the increase of the distance between the first working roll and the second working roll so as to adjust the relative position of the anode catalyst layer and the cathode catalyst layer.

In one embodiment, the catalyst transfer device further comprises a first support assembly and a second support assembly, the first support assembly abuts against the surface of the first working roller and can roll along the circumferential direction of the first working roller, and the first support assembly can apply a support force pointing to the second working roller to the first working roller; the second supporting assembly abuts against the surface of the second working roll and can roll along the circumferential direction of the second working roll, and the second supporting assembly can apply supporting force pointing to the first working roll to the second working roll.

In one embodiment, the first support assembly comprises a first support roller which is abutted against the first working roller, and the first support roller is parallel to the rotation axis of the first working roller and can be driven by the first working roller to rotate;

the second supporting assembly comprises a second supporting roller which is abutted against the second working roller, and the second supporting roller is parallel to the rotation axis of the second working roller and can rotate under the driving of the second working roller.

In one embodiment, the first supporting roller is provided with one, and the diameter of the first supporting roller is larger than that of the first working roller; the number of the second supporting rollers is one, and the diameter of the second supporting rollers is larger than that of the second working rollers.

In one embodiment, the rotation axes of the first support roller, the first working roller, the second working roller and the second support roller are located in the same plane.

In one embodiment, the catalyst transfer device further includes a nip roller abutting against the second working roller to press the cathode transfer film output from the transfer passage against a roller surface of the second working roller.

In one embodiment, the anode feed device comprises a first visual detection assembly positioned on the conveying path of the anode transfer film, wherein the first visual detection assembly can acquire the position information of the anode catalyst layer; the cathode feeding device comprises a second visual detection assembly positioned on the conveying path of the cathode transfer film, and the second visual detection assembly can acquire the position information of the cathode catalyst layer.

In one embodiment, the method further comprises the following steps:

the CCM winding device is used for winding the CCM material belt;

the anode rolling device is used for rolling the anode transfer printing film output from the transfer printing channel;

and the cathode rolling device is used for rolling the cathode transfer printing film output from the transfer printing channel.

In one embodiment, the device further comprises a composite device arranged on the upstream side of the catalyst transfer printing device, and the proton exchange membrane and the anode transfer printing membrane pass through the composite device before entering the transfer printing channel and are combined by the composite device.

In one embodiment, the CCM material belt structure further comprises a film covering device, wherein the film covering device is used for covering one side of the CCM material belt with a back film material belt.

According to the CCM transfer printing equipment, under the normal working condition, the proton exchange membrane, the anode transfer printing membrane and the cathode transfer printing membrane in the transfer printing channel are rolled by the first working roller and the second working roller. Because the anode catalyst layer on the anode transfer printing film and the cathode catalyst layer on the cathode transfer printing film are both coated intermittently and are of discontinuous structures, the anode catalyst layer and the cathode catalyst layer can be completely transferred to the proton exchange membrane, thereby forming discontinuous catalyst layers on the surface of the proton exchange membrane. When the alignment of the anode catalyst layer and the cathode catalyst layer is deviated, the height of the transfer printing channel can be increased by increasing the distance between the first working roller and the second working roller, so that the rolling of the proton exchange membrane, the anode transfer printing film and the cathode transfer printing film is eliminated. At this time, the transport speeds of the cathode transfer film and the cathode transfer film are adjusted, so that the anode catalyst layer and the cathode catalyst layer can be aligned again. As can be seen, the CCM transfer apparatus described above can reduce material waste.

Referring to fig. 1, a CCM transfer apparatus according to an embodiment of the present invention includes a catalyst transfer device 100, a proton membrane supplying device 200, an anode supplying device 300, and a cathode supplying device 400.

Proton membrane supply device 200 is used for providing proton exchange membrane 10, anode supply device 300 is used for providing anode transfer membrane 20, and cathode supply device 400 is used for providing cathode transfer membrane 30. As shown in fig. 10 and 11, the surface of the anode transfer film 20 is intermittently coated with an anode catalyst layer 21, and the surface of the cathode transfer film 30 is intermittently coated with a cathode catalyst layer 31. The anode catalyst layer 21 and the cathode catalyst layer 31 are both discontinuous structures and each include a plurality of block-shaped catalyst layer structures, and the plurality of block-shaped catalyst layer structures are arranged at intervals along the extending direction of the anode transfer film 20 or the cathode transfer film 30.

The anode transfer film 20 and the cathode transfer film 30 can enter the catalyst transfer device 100 together with the proton exchange membrane 10, and the anode transfer film 20 and the cathode transfer film 30 are respectively located on two sides of the proton exchange membrane 10. Specifically, as shown in fig. 1, the anode transfer film 20 is located on the left side of the proton exchange membrane 10, and the right side surface thereof is coated with an anode catalyst layer 21; the right side of the cathode transfer film 30 is located at the right side of the proton exchange membrane 10, and the left side surface thereof is coated with a cathode catalyst layer 31.

Under the pressing action of the catalyst transfer device 100, the anode catalyst layer 21 on the anode transfer film 20 and the cathode catalyst layer 31 on the cathode transfer film 30 are respectively transferred to both sides of the proton exchange membrane 10, so as to obtain the CCM carrier tape 40 having catalyst layers on both sides. As shown in fig. 12, the catalyst layer on the upper surface of the CCM carrier tape 40 is the anode catalyst layer 21 on the original anode transfer film 20, and the catalyst layer on the lower surface is the cathode catalyst layer 31 on the original cathode transfer film 30.

Referring also to fig. 2, the catalyst transfer apparatus 100 includes a first work roll 110 and a second work roll 120. The first working roll 110 and the second working roll 120 are disposed opposite to each other, and form a transfer passage (not shown) through which the anode transfer film 20, the cathode transfer film 30, and the proton exchange membrane 10 can pass.

Further, the distance between the first work roll 110 and the second work roll 120 is adjustable, thereby adjusting the height of the transfer path. The larger the distance between the first work roll 110 and the second work roll 120 is, the higher the height of the transfer path is, and the distance between the first work roll 110 and the second work roll 120 is the distance in the direction of the line connecting the axes, that is, the up-down direction shown in fig. 2. The height adjustment of the transfer path may be achieved by moving the position of the first work roll 110 and/or the second work roll 120. Specifically, in the present embodiment, the first work roll 110 is fixed in position, and the second work roll 120 located below is capable of moving back and forth in the up-down direction.

When the height of the transfer channel is small and smaller than the sum of the thicknesses of the anode transfer film 20, the cathode transfer film 30, and the proton exchange membrane 10, the first working roll 110 and the second working roll 120 can roll the anode transfer film 20, the cathode transfer film 30, and the proton exchange membrane 10 passing through the transfer channel. When the height of the transfer channel is increased and is greater than the sum of the thicknesses of the anode transfer film 20, the cathode transfer film 30 and the proton exchange membrane 10, the first working roll 110 and the second working roll 120 cannot press the cathode transfer film 30 and the cathode transfer film 30, so that the cathode transfer film 30 and the cathode transfer film 30 can independently move in the transfer channel without interfering with each other, thereby conveniently adjusting the relative positions of the anode catalyst layer 21 and the cathode catalyst layer 31.

Under normal operating conditions, the height of the transfer printing channel is small, so that the first working roll 110 and the second working roll 120 are matched to roll the proton exchange membrane 10, the anode transfer printing membrane 20 and the cathode transfer printing membrane 30, so as to transfer the anode catalyst layer 21 on the anode transfer printing membrane 20 and the cathode catalyst layer 31 on the cathode transfer printing membrane 30 to two sides of the proton exchange membrane 10 respectively. Since the anode catalyst layer 21 and the cathode catalyst layer 31 are both discontinuous structures, the anode catalyst layer 21 and the cathode catalyst layer 31 can be transferred to the proton exchange membrane 10, thereby forming discontinuous catalyst layers on the surface of the proton exchange membrane 10. After the transfer, there is no catalyst residue on the anode transfer film 20 and the cathode transfer film 30, so that the waste of materials can be significantly reduced.

Specifically, in the present embodiment, the first work roll 110 and the second work roll 120 are provided with heating elements (not shown) inside. The heating assembly can be an electromagnetic heating assembly, an electrical bar heating assembly and the like, and can heat the anode transfer film 20, the cathode transfer film 30 and the proton exchange membrane 10 in the transfer process, so that the transfer rate of the catalyst is improved, and the transfer effect is improved.

Because the anode catalyst layer 21 and the cathode catalyst layer 31 are both of a discontinuous structure, and errors and defects are present in the processing process, after long-time accumulation, the anode catalyst layer 21 and the cathode catalyst layer 31 may have a misalignment when entering the rolling channel, that is, the block-shaped catalyst layer structure in the anode catalyst layer 21 cannot be aligned with the block-shaped catalyst layer structure in the cathode catalyst layer 31. If the anode catalyst layer 21 and the cathode catalyst layer 31 with the misalignment are directly transferred to the two sides of the proton exchange membrane 10, the catalyst layers on the two sides of the CCM carrier tape 40 may not be aligned, and the CCM carrier tape 40 may be discarded.

Referring to fig. 4 and 5, in the present embodiment, the anode feeding device 300 includes a first visual inspection device 310 located on the conveying path of the anode transfer film 20, wherein the first visual inspection device 310 can acquire the position information of the anode catalyst layer 21; the cathode feeding apparatus 400 includes a second visual inspection assembly 410 on the conveying path of the cathode transfer sheet 30, and the second visual inspection assembly 410 can acquire positional information of the cathode catalyst layer 31.

The first visual inspection device 310 and the second visual inspection device 410 have the same structure and can be CCD cameras. After the first visual inspection unit 310 and the second visual inspection unit 410 respectively detect the position information of the anode catalyst layer 21 and the cathode catalyst layer 31, the alignment deviation between the anode catalyst layer 21 and the cathode catalyst layer 31 can be detected by comparison analysis.

When the misalignment of the anode catalyst layer 21 and the cathode catalyst layer 31 is detected, the height of the transfer channel can be increased by increasing the distance between the first working roll 110 and the second working roll 120, so as to release the roll pressure on the proton exchange membrane 10, the anode transfer membrane 20, and the cathode transfer membrane 30. At this time, the

cathode transfer films

30 and 30 can be independently transported, and the transport speeds of the

cathode transfer films

30 and 30 are adjusted, respectively, so that the anode catalyst layers 21 and the cathode catalyst layers 31 can be aligned again. After the alignment is completed, the height of the transfer printing channel is restored to the size of the normal working condition, and the cathode transfer printing film 30 are synchronized again, so that the transfer printing operation can be continuously performed.

In addition, compared with the traditional gravure roll transfer printing process, the adaptability of the CCM transfer printing device is higher, parts of the device do not need to be replaced when the CCM transfer printing device is used for processing products of other models, and only the anode transfer printing film 20 and the cathode transfer printing film 30 with corresponding specifications need to be replaced and can be used along with the proton exchange membrane 10. Moreover, since the pressure between the first working roll 110 and the second working roll 120 is relatively stable during the rolling process, the edge of the catalyst layer of the CCM material tape 40 can be prevented from being jagged.

Compared with the traditional transfer printing process by the lifting roller, the CCM transfer printing equipment does not need to frequently change the positions of the first working roller 110 and the second working roller 120 in the transfer printing process, so that the transfer printing efficiency is higher, and the production capacity is favorably improved. Similarly, the pressure between the first working roll 110 and the second working roll 120 is relatively stable during the rolling process, so that the edge of the catalyst layer of the CCM material tape 40 can be prevented from being jagged.

Referring to fig. 2 again, in the present embodiment, the catalyst transfer printing apparatus 100 further includes a first supporting assembly 130 and a second supporting assembly 140. The first supporting assembly 130 is supported against the surface of the first working roll 110 and can roll along the circumferential direction of the first working roll 110. Also, the first support assembly 130 can apply a supporting force directed toward the second work roll 120 to the first work roll 110.

The first supporting member 130 may be in point contact or line contact with the surface of the first working roll 110, and the acting force applied to the first working roll 110 by the first supporting member 130 may be one or more than one, as long as it is ensured that the direction of the resultant force of the acting forces is directed to the second working roll 120. Under the supporting effect of the first supporting assembly 130, the first working roll 110 is not easy to bend during the transfer process. Moreover, since the first support assembly is added to support the first work roll 110, the compressive strength of the first work roll 110 itself can be reduced properly, and the diameter of the first work roll 110 is smaller than that of the conventional work roll. In general, the work rolls in the conventional transfer apparatus each have a diameter of 200 mm or more, and the diameter of the first work roll 110 in the present embodiment may be set to 100 mm or less.

The second support element 140 is substantially identical in structure and function to the first support element 130. The second supporting assembly 140 abuts against the surface of the second working roll 120 and can roll along the circumferential direction of the second working roll 120, and the second supporting assembly 140 can apply a supporting force pointing to the first working roll 110 to the second working roll 120. Under the supporting action of the second supporting assembly 140, the second working roll 120 is also less prone to bending during the transfer process, and has a smaller diameter than a conventional working roll.

Therefore, on the premise of a certain pressure, the transfer pressure between the first working roll 110 and the second working roll 120 is increased, and the transfer rate of the catalyst is increased, so that the catalyst residue is reduced, and the transfer effect is improved. Moreover, the straightness of the edge of the catalyst layer in the width direction on the CCM carrier tape 40 can be ensured.

It should be noted that when the distance between the first work roll 110 and the second work roll 120 is adjusted, the first support assembly 130 and the second support assembly 140 move synchronously with the first work roll 110 and the second work roll 120.

Further, in this embodiment, the first supporting assembly 130 includes a first supporting roller 131 abutting against the first working roller 110, and the first supporting roller 131 is parallel to the rotation axis of the first working roller 110 and can be driven by the first working roller 110 to rotate. Moreover, the second supporting assembly 140 includes a second supporting roller 141 abutting against the second working roller 120, and the second supporting roller 141 is parallel to the rotation axis of the second working roller 120 and can be driven by the second working roller 120 to rotate.

At this time, the first supporting member 130 is in line contact with the first work roll 110, and the contact position extends in the axial direction of the first work roll 110. The second support member 140 is also in line contact with the second work roll 120, and the contact position extends in the axial direction of the second work roll 120. Therefore, the first supporting assembly 130 and the second supporting assembly 140 support the first working roll 110 and the second working roll 120 better.

Specifically, in the present embodiment, one first supporting roller 131 is provided, and the diameter of the first supporting roller 131 is larger than that of the first work roller 110. Also, one second support roller 141 is provided, and the diameter of the second support roller 141 is larger than that of the second work roller 120.

The first support roller 131 and the second support roller 141 having a large diameter have high support strength and can provide better support. In addition, since there is only one first support roller 131 and one second support roller 141, the structures of the first support unit 130 and the second support unit 140 can be simplified.

Further, in the present embodiment, the rotation axes of the first support roller 131, the first work roller 110, the second work roller 120, and the second support roller 141 are located in the same plane. As can be seen, the first supporting roller 131 and the second supporting roller 141 cooperate with each other to sandwich the first working roller 110 and the second working roller 120, so that the supporting effect is better.

It should be noted that, in other embodiments, the first supporting component 130 and the second supporting component 140 may have other structures. For example, at least two contact points may be formed between the first supporting member 130 and the first working roll 110 by rolling members such as balls and rollers, and the at least two contact points are spaced apart along the axial direction of the first working roll 110. Likewise, the second support assembly 140 may define at least two contact points with the second work roll 120, and the at least two contact points are spaced apart along the axial direction of the second work roll 120.

In addition, in the present embodiment, the catalyst transfer device 100 further includes a pressure roller 150, and the pressure roller 150 abuts against the second work roller 120 to press the cathode transfer film 30 output from the transfer passage against the roller surface of the second work roller 120.

The line connecting the center line of the nip roller 150 and the center line of the second work roller 120 is substantially perpendicular to the connection of the center line of the second work roller 120 and the center line of the first work roller 110. Under the action of the pressure roller 150, the cathode transfer film 30 can form a larger envelope angle on the roller surface of the second work roller 120, thereby being beneficial to improving the transfer effect. Further, the nip roller 150 can maintain the cathode transfer film 30 in good contact with the second work roll 120 when the second work roll 120 moves up and down.

Referring to fig. 3, in the present embodiment, the proton membrane supplying apparatus 200 includes a proton membrane unwinding assembly 210, a membrane peeling assembly 220, and a back membrane winding assembly 230.

The proton membrane unwinding assembly 210 may be an unwinding shaft, the proton exchange membrane 10 with the protective membrane 11 on one side is stored in the proton membrane unwinding assembly 210 in advance, and the proton membrane unwinding assembly 210 unwinds at a preset speed. When the proton exchange membrane 10 passes through the membrane peeling assembly 220, the protective membrane 11 is separated from the proton exchange membrane 10 under the traction of the back membrane rolling assembly 230, and the protective membrane 11 is rolled by the back membrane rolling assembly 230.

Referring to fig. 4 again, in the present embodiment, the anode feeding device 300 further includes an anode transfer film unwinding assembly 320 and an anode preheating assembly 330.

The anode transfer film unwinding assembly 320 may be an unwinding shaft, and the pre-coated and dried anode transfer film 20 may be stored in the anode transfer film unwinding assembly 320 and may be unwound by the anode transfer film unwinding assembly 320 at a predetermined speed. The anode preheating assembly 330 can preheat the anode transfer film 20 in the tape transport process, thereby reducing the heat conduction time in the transfer process and improving the transfer quality and speed. Specifically, the anode preheating assembly 330 may be preheated by electromagnetic heating, infrared heating, or the like.

In addition, the anode feeding device 300 also includes a roll diameter measuring assembly (not shown), a roller (not shown), a static removing assembly (not shown), and a belt splicing platform (not shown). In order to realize automatic unwinding and deviation correction, the anode feeding device 300 further includes a deviation correction follower roller (not shown), a deviation correction sensor (not shown), a tension sensor (not shown), and the like on the tape running path of the anode transfer film 20.

It should be noted that in other embodiments, the anode feeding device 300 can also be used to prepare the anode transfer film 20 on-line in a real-time catalyst coating manner.

Referring to fig. 5 again, in the present embodiment, the cathode supply device 400 further includes a cathode transfer film unwinding assembly 420 and a cathode preheating assembly 430.

The cathode transfer film unwinding assembly 420 may also be an unwinding shaft, and the pre-coated and dried cathode transfer film 30 may be stored in the cathode transfer film unwinding assembly 420 and may be unwound by the cathode transfer film unwinding assembly 420 at a predetermined speed. The cathode preheating assembly 430 can preheat the cathode transfer film 30 during the tape running process, thereby reducing the heat conduction time during the transfer process and improving the transfer quality and speed. Specifically, the cathode preheating assembly 430 may be preheated by electromagnetic heating, infrared heating, or the like.

In addition, the cathode feeding device 400 also includes a roll diameter measuring assembly (not shown), a roller (not shown), a static removing assembly (not shown), and a belt connecting platform (not shown). In order to realize automatic unwinding and deviation correction, the cathode feeding device 400 further includes a deviation correction follower roller (not shown), a deviation correction sensor (not shown), a tension swing roller (not shown), and the like on the running path of the cathode transfer film 30.

In the CCM transfer apparatus, under normal operating conditions, the proton exchange membrane 10, the anode transfer film 20, and the cathode transfer film 30 in the transfer channel are rolled by the first working roll 110 and the second working roll 120. Since the anode catalyst layer 21 on the anode transfer film 20 and the cathode catalyst layer 31 on the cathode transfer film 30 are both intermittently coated and have a discontinuous structure, the anode catalyst layer 21 and the cathode catalyst layer 31 can be completely transferred to the proton exchange membrane 10, so that a discontinuous catalyst layer is formed on the surface of the proton exchange membrane 10. When the alignment of the anode catalyst layer 21 and the cathode catalyst layer 31 is deviated, the distance between the first working roll 110 and the second working roll 120 is increased to increase the height of the transfer channel, so as to release the roll pressing of the proton exchange membrane 10, the anode transfer film 20, and the cathode transfer film 30. At this time, the anode catalyst layer 21 and the cathode catalyst layer 31 can be aligned again by adjusting the transport speeds of the cathode transfer film 30 and the cathode transfer film 30, respectively. As can be seen, the CCM transfer apparatus described above can reduce material waste.
