[0032] The embodiments of the present application are described below in detail, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary only, and are used to explain the present application, and should not be understood as a limitation of the present application.

[0033] It should be noted that, as shown in Figure 1 The five-in-one packaging of the membrane electrode 200 is to stack and package the three-layer catalyst-coated proton membrane 202 with the first frame 201 and the second frame 203 respectively, wherein, in the present embodiment, the first frame 201 is the lower frame, the second frame 203 is the upper frame, and the catalyst-coated proton membrane 202 includes a proton membrane and an anode catalyst layer and a cathode catalyst layer arranged on both sides of the proton membrane.

[0034] Further, as shown in Figures 1-3 The first frame 201 and the second frame 203 can be configured as rectangular frames or circular frames, and the specific configuration is determined according to the shape of the catalyst-coated proton membrane 202. The present application takes the first frame 201 and the second frame 203 configured as rectangular frames as an example for description, wherein the middle region of the first frame 201 and the second frame 203 is hollowed out to form a hollow region 204, that is, the shape of the first frame 201 and the second frame 203 is a rectangular ring. It should be noted that, as shown in Figure 3 The middle hollow region 204 of the first frame 201 and the second frame 203 is smaller than the size of the catalyst-coated proton membrane 202. When the catalyst-coated proton membrane 202 is placed on the first frame 201, the catalyst-coated proton membrane 202 and the first frame 201 form a lap region 205, and the lap region 205 of the first frame 201 circumferentially surrounds the hollow region 204 of the first frame 201, as shown in Figure 1 When the second frame 203 is placed on the catalyst-coated proton membrane 202, the catalyst-coated proton membrane 202 and the second frame 203 also form a lap region 205, and the lap region 205 of the second frame 203 circumferentially surrounds the hollow region 204 of the second frame 203.

[0035] Further, in order to facilitate the five-in-one packaging of the membrane electrode 200, the size of the second frame 203 is usually the same as that of the first frame 201, that is, the length, width and height of the second frame 203 are equal to those of the first frame 201, and the middle hollow region 204 of the second frame 203 is the same in size and position as the middle hollow region 204 of the first frame 201.

[0036] In the related art, in the five-in-one packaging process of the membrane electrode 200, the first frame 201 is horizontally placed on a horizontal loading platform, and then the cut catalyst coating proton membrane 202 is placed on the first frame 201 by a mechanical hand. During the placement process, the catalyst coating proton membrane 202 is guaranteed to be coincident with the center of the hollow area 204 of the first frame 201, and the catalyst coating proton membrane 202 is overlapped and pre-bonded with the edge of the hollow area 204 of the first frame 201. Then, the horizontal loading platform is vacuumized to adsorb and fix the catalyst coating proton membrane 202 and the first frame 201. However, since the first frame 201 has a hollow area 204 in the middle, when the catalyst coating proton membrane 202 is adsorbed and fixed, the edge of the catalyst coating proton membrane 202 is curled and raised due to the overlap with the first frame 201, which cannot be adsorbed by vacuum (the frame is not air permeable) and is curled and raised. When the second frame 203 is placed on the catalyst coating proton membrane 202, the corner is prone to be folded, which may cause the overlap width to not meet the sealing requirement and the membrane electrode 200 to leak after packaging.

[0037] Based on this, the application provides a packaging device 100 for a membrane electrode. When the mounting platform 1 adsorbs the catalyst coating proton membrane 202 and the first frame 201, the mounting portion 12 can support the catalyst coating proton membrane 202 on the hollow area 204, prevent the catalyst coating proton membrane 202 from bending towards the hollow area 204 of the first frame 201, avoid the edge of the catalyst coating proton membrane 202 from being curled and raised, meet the sealing requirement of the membrane electrode 200, and reduce the risk of the membrane electrode 200 leaking.

[0038] The packaging device 100 for a membrane electrode according to the embodiments of the application will be described below with reference to the accompanying drawings.

[0039] As shown in Figure 4 The packaging device 100 according to the first aspect of the application comprises a mounting platform 1 and a first transfer platform 2. The mounting platform 1 is used to adsorb and position the first frame 201 and the catalyst coating proton membrane 202 placed on the first frame 201. The mounting platform 1 has a support surface 11 and a mounting portion 12. The support surface 11 is used to support the first frame 201. The mounting portion 12 is protrudingly arranged on the support surface 11 and is used to be inserted into the hollow area 204 of the first frame 201. The upper surface of the mounting portion 12 is used to be bonded with the lower surface of the catalyst coating proton membrane 202. The first transfer platform 2 has a pressing portion 21 on the side opposite to the mounting platform 1. The pressing portion 21 is used to press the catalyst coating proton membrane 202, so that the edge of the catalyst coating proton membrane 202 is bonded with the overlap area 205 of the first frame 201.

[0040] Specifically, the mounting platform 1 is used to place the first frame 201, and the mounting platform 1 is provided with a support surface 11 and a mounting portion 12, wherein the support surface 11 is a horizontal support surface, and the mounting portion 12 can be configured as a mounting protrusion, wherein the mounting protrusion protrudes in a direction away from the support surface 11, the orthographic projection shape of the mounting protrusion matches the shape of the hollow area 204 of the first frame 201, for example, the hollow area 204 of the first frame 201 is a rectangular area, and the orthographic projection shape of the mounting protrusion is a rectangle, the hollow area 204 of the first frame 201 is a circular area, and the orthographic projection shape of the mounting protrusion is a circle, and the size of the mounting protrusion is equal to or slightly smaller than the size of the hollow area 204 of the first frame 201, for example, the outer side wall of the mounting protrusion and the inner side wall of the hollow area 204 are in clearance fit, thereby ensuring the normal assembly of the first frame 201 and the mounting protrusion.

[0041] When the first frame 201 is placed, the lower surface of the first frame 201 is in abutting fit with the support surface 11, and at the same time, the hollow area 204 of the first frame 201 is in plug-in assembly with the mounting portion 12 of the mounting platform 1, for example, the mounting portion 12 can be configured as but is not limited to a lifting piece, the mounting portion 12 can extend into the hollow area 204 of the first frame 201, so that the upper surface of the mounting portion 12 and the upper surface of the first frame 201 are in the same horizontal plane, thereby making the edge of the catalyst coating proton membrane 202 abut the lap area 205 of the first frame 201, that is, when the mounting platform 1 adsorbs and fixes the catalyst coating proton membrane 202, the mounting portion 12 can play a certain supporting role on the catalyst coating proton membrane 202 in the hollow area 204 of the first frame 201, and it should be noted that in some embodiments of the present application, the cooperation of the support surface 11 and the mounting portion 12 can ensure that the upper surface of the first frame 201 and the upper surface of the mounting portion 12 are in the same horizontal plane, which will not be illustrated one by one here.

[0042] After the first frame 201 is installed on the installation platform 1, the first transfer platform 2 is used to place the catalyst coating proton membrane 202 on the first frame 201 and make the edge of the catalyst coating proton membrane 202 opposite to the lap area 205 of the first frame 201, that is, the first transfer platform 2 can be configured as but not limited to a mechanical gripper, a vacuum suction device, etc., and the first transfer platform 2 is used to transfer and place the catalyst coating proton membrane 202 on the first frame 201. It can be understood that the installation platform 1 can adsorb and position the first frame 201 and the catalyst coating proton membrane 202 placed on the first frame 201, and during the placement process, it is necessary to ensure that the catalyst coating proton membrane 202 is coincident with the center of the hollow area 204 of the first frame 201, and the edge of the catalyst coating proton membrane 202 is lapped with the lap area 205 of the first frame 201. Optionally, the lap area 205 of the first frame 201 is pre-provided with adhesive, and when the catalyst coating proton membrane 202 is placed on the first frame 201, the adhesive of the first frame 201 can pre-bond the edge of the catalyst coating proton membrane 202 in the lap area 205.

[0043] Further, as shown in Figure 4 , the lower surface of the first transfer platform 2 is also provided with a pressing part 21, which can press the edge of the catalyst coating proton membrane 202 and the lap area 205 of the first frame 201 after the first transfer platform 2 places the catalyst coating proton membrane 202 on the first frame 201. For example, the pressing part 21 can be an elastic pressing part, or a pneumatic pressing part, or a hydraulic pressing part, which can press the lap area 205 of the first frame 201. Here, it will not be described any further. In this way, the pressing part 21 can press the lap area 205 of the first frame 201 to ensure that the catalyst coating proton membrane 202 and the first frame 201 are tightly connected together by the adhesive. When the installation platform 1 adsorbs and fixes the catalyst coating proton membrane 202 and the first frame 201 by vacuumizing, the installation part 12 can play a certain supporting role to support the catalyst coating proton membrane 202 above the hollow area 204 of the first frame 201, prevent the catalyst coating proton membrane 202 from bending towards the hollow area 204 of the first frame 201, and thus avoid the edge of the catalyst coating proton membrane 202 from curling and rising.

[0044] According to the packaging device 100 for the membrane electrode provided in the embodiment of the present application, when the mounting platform 1 adsorbs the catalyst coating proton membrane 202 and the first frame 201, the mounting portion 12 can support the catalyst coating proton membrane 202 on the hollowed-out area 204, prevent the catalyst coating proton membrane 202 from bending towards the hollowed-out area 204 of the first frame 201, avoid the curling and lifting of the edge of the catalyst coating proton membrane 202, meet the sealing requirement of the membrane electrode 200, and reduce the risk of air leakage of the membrane electrode 200.

[0045] In some examples of the present application, as shown in Figure 4 The mounting platform 1 is provided with a vacuum adsorption portion for adsorbing and positioning the first frame 201 and the catalyst coating proton membrane 202.

[0046] In some examples of the present application, the pressing portion 21 is a pressing protrusion. Specifically, the pressing portion 21 can be configured as a pressing protrusion, which is arranged corresponding to the lap joint area of the first frame, and is arranged on the lower surface of the first transfer platform 2, protrudes away from the lower surface of the first transfer platform 2, and is arranged corresponding to the lap joint area 205 of the first frame 201. For example, the pressing protrusion can be configured as a ring-shaped protrusion matched with the lap joint area 205, that is, the pressing protrusion is arranged around the hollowed-out area 204 of the first frame 201. In this way, when the pressing protrusion presses the edge of the catalyst coating proton membrane 202 and the lap joint area 205 of the first frame 201, the stress on the catalyst coating proton membrane 202 and the lap joint area 205 of the first frame 201 can be increased, which is beneficial to further ensure the adhesion of the catalyst coating proton membrane 202 and the first frame 201.

[0047] In some examples of the present application, as shown in Figure 4 Specifically, at least one pressing protrusion can be arranged on each of the four circumferential sides of the lap joint area 204 of the first frame 201. In this way, the lap joint area 204 of the first frame 201 and the catalyst coating proton membrane 202 can be better adhered and stressed.

[0048] In some examples of the utility model, the press protrusions are multiple, and the multiple press protrusions are arranged at intervals in the circumferential direction of the first transfer platform 2. That is, the lower surface of the first frame 201 can be provided with multiple press protrusions, which can be directional protrusions or circular protrusions, and the multiple press protrusions are arranged at intervals in the circumferential direction of the first transfer platform 2, that is, the multiple press protrusions are arranged in a ring shape at intervals in the circumferential direction of the first transfer platform 2, so that the stress on the catalyst coating proton membrane 202 and the lapping area 205 of the first frame 201 can be increased, and the adhesion between the catalyst coating proton membrane 202 and the first frame 201 can be further ensured.

[0049] In some examples of the utility model, the width of the press protrusion is consistent with the width of the lapping area 205 of the first frame 201. That is, as shown in the figure, the width of the press protrusion can be equal to or slightly greater than the width of the lapping area 205 of the first frame 201, so that when the edge of the catalyst coating proton membrane 202 and the lapping area 205 of the first frame 201 are pressed, the press protrusion can ensure the pressing area, and the adhesion between the catalyst coating proton membrane 202 and the first frame 201 can be improved. Figure 4

[0050] In some examples of the utility model, the height of the press protrusion is H, and the relationship formula 0.15mm≤H≤0.25mm is met. That is, the height of the press protrusion is greater than or equal to 0.15mm and less than or equal to 0.25mm, for example, the height of the press protrusion can be 0.15mm, 0.2mm or 0.25mm, which is set according to actual needs, and is not limited here, so that the height of the press protrusion can be moderate, and the pressing requirement of the lapping area 205 can also be met.

[0051] Further, the width D of the press protrusion meets the relationship formula 3mm≤D≤5mm. That is, the width of the lapping area 205 of the first frame 201 is generally greater than or equal to 3mm and less than or equal to 5mm, so the width of the press protrusion is also greater than or equal to 3mm and less than or equal to 5mm, for example, the height of the press protrusion can be 3mm, 4mm or 5mm, which is set according to the width of the lapping area 205 of the first frame 201, and is not limited here, so that the width of the press protrusion can be moderate, and the pressing requirement of the lapping area 205 can also be met.

[0052] In some examples of the utility model, the press part 21 is a detachable part. That is, the press part 21 can be detached and replaced from the first transfer platform 2, so that the press part 21 suitable for the lapping area 205 can be replaced, so that the pressing effect on the lapping area 205 can be improved.​

[0053] In some examples of the present application, the pressing part 21 is a metal part. Specifically, the pressing part 21 can be made of stainless steel or aluminum alloy, so as to improve the rigidity of the pressing part 21 and indirectly improve the pressing pressure of the pressing part 21.

[0054] In some examples of the present application, the packaging device 100 further comprises a second transfer platform, which is used to bond the lap joint area 205 of the second frame 203 with the edge of the catalyst coated proton membrane 202.

[0055] Specifically, in the five-in-one packaging process of the membrane electrode 200, when the installation platform 1 adsorbs and fixes the catalyst coated proton membrane 202 and the first frame 201, and the second transfer platform places the second frame 203 on the catalyst coated proton membrane 202, the hollow area 204 of the second frame 203 is guaranteed to be coincident with the center of the catalyst coated proton membrane 202, and the lap joint area 205 of the second frame 203 is bonded with the edge of the catalyst coated proton membrane 202. It should be noted that the lap joint area 205 of the second frame 203 is pre-provided with adhesive, and when the second frame 203 is placed on the catalyst coated proton membrane 202, the adhesive of the second frame 203 can bond the catalyst coated proton membrane 202 in the lap joint area 205. Further, the five-in-one membrane electrode after pre-bonding needs to be transferred into a hot pressing cavity for hot pressing, and after hot pressing, a five-in-one membrane electrode meeting the packaging requirements is formed. In this process, since the edge of the catalyst coated proton membrane 202 does not curl up, when the second frame 203 is placed on the catalyst coated proton membrane 202, there is also no corner, which well guarantees the sealing requirement of the membrane electrode 200 and reduces the risk of gas leakage of the membrane electrode 200.

[0056] The packaging system according to the second aspect of the present application comprises the packaging device 100 according to the first aspect of the present application.

[0057] According to the packaging system of the present application, when the installation platform 1 adsorbs the catalyst coated proton membrane 202 and the first frame 201, the installation part 12 can support the catalyst coated proton membrane 202 on the hollow area 204, preventing the catalyst coated proton membrane 202 from bending towards the hollow area 204 of the first frame 201, avoiding the curling of the edge of the catalyst coated proton membrane 202, meeting the sealing requirement of the membrane electrode 200, and reducing the risk of gas leakage of the membrane electrode 200.
