[0061] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0062] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0064] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0065] Electrolyzers and fuel cell devices are usually composed of multiple membrane electrode assemblies stacked in the height direction. When in use, the multiple membrane electrode assemblies need to be compressed to prevent deformation. When any membrane electrode assembly fails and needs to be replaced, the normally working membrane electrode assemblies need to be disassembled layer by layer until the faulty membrane electrode assembly is removed. During the disassembly process, the other normally working membrane electrode assemblies that have been removed cannot be subjected to the compression force and are prone to deformation, resulting in damage to the normally working membrane electrode assemblies.

[0066] In order to solve this technical problem, the embodiment of the present application provides a changing mechanism 1, such as Figure 1 As shown, the changing mechanism 1 includes: a mounting frame 11 and a lifting assembly 12, wherein the mounting frame 11 has a accommodating space for accommodating the device to be changed, the accommodating space has an opening, the device to be changed includes a plurality of stacking members, the lifting assembly 12 is detachably mounted on the mounting frame 11, and at least a portion of the lifting assembly 12 can move along a first direction Z relative to the mounting frame 11 to drive at least a portion of the stacking members to move along the first direction Z so that the stacking members can be changed through the opening.

[0067] In this embodiment, a mounting frame 11 with a storage space is provided to provide a placement space for the device to be replaced, and to provide support for the lifting assembly 12 and the device to be replaced, and the storage space has an opening, through which the stacked pieces to be replaced can be taken out and placed. When the device to be replaced is replaced, along the first direction Z, the lifting assembly 12 can drive the multiple adjacent stacked pieces above the stacked piece to be replaced to move away from the stacked piece to be replaced along the first direction Z, so that the stacked piece to be replaced is located on the surface of the remaining stacked pieces, so that the user can take out and replace the stacked piece to be replaced, improve the replacement efficiency, and significantly save the replacement time. At the same time, the lifting assembly 12 can press the multiple stacked pieces it lifts, that is, during the lifting process, the multiple stacked pieces located above the stacked piece to be replaced are still in a pressed state, avoiding deformation and damage of the stacked pieces due to lack of pressing, and reducing the impact on other normal stacked pieces during the replacement process.

[0068] Among them, in the embodiment of the present application, the first direction Z is the height direction of the changing mechanism 1.

[0069] The replacement mechanism 1 is used to replace the stack of the equipment to be replaced, wherein the equipment to be replaced can be an electrolyzer or a fuel cell, and the stack is a membrane electrode assembly 18. The replacement mechanism 1 can be used to take out the membrane electrode assembly 181 of the electrolyzer or fuel cell to be replaced at one time, which can significantly improve the replacement efficiency and save replacement time. The equipment to be replaced can also be other equipment. The embodiment of the present application is described by taking the equipment to be replaced as an electrolyzer or a fuel cell and the stack as a membrane electrode assembly 18 as an example.

[0070] like Figure 2As shown, the electrolytic cell includes a plurality of stacked membrane electrode assemblies 18. When any membrane electrode assembly 18 in the electrolytic cell fails and needs to be replaced, the electrolytic cell is first placed in the accommodating space of the mounting frame 11, and the lifting assembly 12 is connected to the adjacent membrane electrode assembly 18 above the membrane electrode assembly 181 to be replaced. The lifting assembly 12 drives the plurality of membrane electrode assemblies 18 above the membrane electrode assembly 181 to be replaced to move upward, so that the membrane electrode assembly 181 to be replaced is located on the surface of the remaining membrane electrode assemblies 18, so that the membrane electrode assembly 181 to be replaced can be taken out and replaced. At the same time, the lifting assembly 12 can press the plurality of membrane electrode assemblies 18 it lifts to prevent them from deformation and damage.

[0071] In a specific embodiment, Figure 1 and Figure 3 As shown, the replacement mechanism 1 may include a plurality of positioning columns 17 detachably connected to the mounting frame 11, the positioning columns 17 are arranged on both sides of the accommodating space along the second direction X and / or the third direction Y, and the positioning columns 17 are used to abut against the device to be replaced.

[0072] In the present embodiment, after the electrolytic cell device is installed on the mounting frame 11, a plurality of positioning posts 17 can be connected to the mounting frame 11 along the second direction X and / or the third direction Y of the accommodating space and abut against the membrane electrode assembly 18. By providing a plurality of positioning posts 17, the membrane electrode assembly 18 can be limited to avoid the membrane electrode assembly 18 from being offset when moving along the first direction Z, causing the membrane electrode assembly 18 to fall off, thereby improving the safety of the replacement mechanism 1.

[0073] In this embodiment, when replacing the membrane electrode assembly 181 to be replaced, part of the positioning posts 17 can be disassembled first so that the membrane electrode assembly 181 to be replaced can be taken out and replaced.

[0074] Specifically, the mounting frame 11 is provided with a mounting hole for the positioning column 17 to pass through, so that the positioning column 17 can be installed on the mounting frame 11 through the mounting hole, or removed from the mounting frame 11 through the mounting hole.

[0075] Among them, in the embodiment of the present application, the second direction X is the width direction of the changing mechanism 1, and the third direction Y is the length direction of the changing mechanism 1.

[0076] In a specific embodiment, Figure 2 , Figure 4 and Figure 5 As shown, the lifting assembly 12 includes a lifting member 121 and a moving member 122 connected to the lifting member 121 . The moving member 122 is movably connected to the mounting frame 11 . The lifting member 121 is used to be inserted between adjacent stacking members and can move along the first direction Z driven by the moving member 122 .

[0077] In the present embodiment, when replacing the membrane electrode assembly 181 to be replaced in the electrolytic cell device, the lifting member 121 is first inserted between the membrane electrode assembly 181 to be replaced and the adjacent membrane electrode assembly 18 above it, so that the lifting member 121 abuts against the bottom surface of the adjacent membrane electrode assembly 18 above it, and then the moving member 122 is connected to the lifting member 121, so that the lifting member 121 can move along the first direction Z driven by the moving member 122, and then the lifting member 121 drives all the membrane electrode assemblies 18 above the membrane electrode assembly 181 to be replaced to move along the first direction Z, so that the membrane electrode assembly 181 to be replaced is located on the upper surface of the remaining membrane electrode assemblies 18, which is convenient for replacement.

[0078] In a specific embodiment, Figure 4 and Figure 6 As shown, the moving member 122 is provided with a first connecting hole 122a extending along the first direction Z, and the lifting member 121 and the moving member 122 are detachably connected via a first connecting member 122b, which passes through the first connecting hole 122a so that the lifting member 121 can move along the first connecting hole 122a.

[0079] In this embodiment, by providing the first connection hole 122a and the first connection member 122b, it is convenient to realize the detachable connection between the lifting member 121 and the moving member 122, so that after the replacement of the membrane electrode assembly 181 to be replaced is completed, the lifting assembly can be removed, and at the same time, the driving member 13 can press the replaced electrolyzer device to make the replaced electrolyzer device work normally. The first connection hole 122a is extended along the first direction Z, so that the lifting member 121 can move through the first connection hole 122a, that is, along the first direction Z, the lifting member 121 can be installed at different positions of the moving member 122, so that the lifting member 121 can be inserted between the membrane electrode assemblies 18 at different positions, so as to facilitate the replacement of the membrane electrode assemblies 18 at different positions along the first direction Z, and when there are multiple membrane electrode assemblies 181 to be replaced in the electrolyzer device, the position of the lifting member 121 relative to the moving member 122 can be adjusted to achieve the replacement of multiple membrane electrode assemblies 18.

[0080] The first connecting member 122b may be a screw, so that the lifting member 121 can slide relative to the first connecting hole 122a while realizing the detachable connection between the moving member 122 and the lifting member 121.

[0081] In a specific embodiment, Figure 6 As shown, the dressing mechanism 1 also includes a driving member 13, which can slide along the first direction Z relative to the mounting frame 11. The dressing mechanism 1 includes a plurality of lifting assemblies 12, and the moving member 122 of each lifting assembly 12 is detachably connected to the driving member 13.

[0082] In this embodiment, by providing a driving member 13 with a larger area, it can be connected to the moving members 122 of multiple lifting assemblies 12 at the same time, so that the multiple lifting assemblies 12 can move simultaneously along the first direction Z under the drive of the driving member 13, so that the movement of each lifting assembly 12 is more stable. At the same time, multiple lifting assemblies 12 connected to the driving member 13 are provided to ensure that the lifting assemblies 12 always move along the first direction Z under the drive of the same driving member 13, to prevent the membrane electrode assembly 18 from being damaged when the movement direction deviates from the first direction Z, and to ensure that the membrane electrode assembly 18 is always subjected to the pressing force along the first direction Z and remains horizontal, to avoid damage to the membrane electrode assembly 18 due to deformation.

[0083] In a specific embodiment, Figure 5 As shown, the lifting member 121 includes a first connecting end 121a and a first plugging end 121b connected to each other. The first connecting end 121a is detachably connected to the moving member 122, and the first plugging end 121b is used to be inserted between adjacent stacking members. The cross-section of the lifting member 121 is L-shaped.

[0084] In this embodiment, the cross-section of the lifting member 121 is L-shaped, that is, the first connecting end 121a and the first plug-in end 121b are perpendicular and connected, so that after the first connecting end 121a is connected to the moving member 122, the first plug-in end 122b is perpendicular to the moving member 122, so that the first plug-in end 121b can be inserted between the membrane electrode assembly 18 and abut against the bottom surface of the membrane electrode assembly 18, so that the lifting member 121 can drive the membrane electrode assembly 18 to move, and the connection area between the first plug-in end 121b and the bottom surface of the membrane electrode assembly 18 is large, thereby reducing the stress on the membrane electrode assembly 18 during the lifting process.

[0085] In this embodiment, the thickness of the first connecting end 121a is greater than the thickness of the first plug-in end 121b, and the first plug-in end 121b is wedge-shaped, so that it is easy to insert between the adjacent membrane electrode assemblies 18 during the replacement process. At the same time, the thickness of the first plug-in end 121b is relatively small. After the first plug-in end 121b is inserted between the membrane electrode assemblies 18, the deformation caused by the first plug-in end 121b on the adjacent membrane electrode assemblies 18 is relatively small, thereby reducing the impact of the first plug-in end 121b on the adjacent membrane electrode assemblies 18 during the insertion process.

[0086] The lifting member 121 may also be provided with a plurality of first ribs 121c, such as Figure 5 As shown, the first rib 121c is located at the connection between the first connecting end 121a and the first plug-in end 121b, which strengthens the connection between the first connecting end 121a and the first plug-in end 121b, extends the service life of the lifting member 121, and avoids deformation of the lifting member 121 when a large number of membrane electrode assemblies 18 are lifted, causing the membrane electrode assembly 18 to fall off, thereby improving the safety of the replacement mechanism 1.

[0087] In a specific embodiment, Figure 6 As shown, the mounting frame 11 includes a top plate 111, a bottom plate 112 and a connecting column 113. The top plate 111 and the bottom plate 112 are fixedly connected to the connecting column 113, and the top plate 111 is located at the end of the driving member 13 away from the bottom plate 112. The driving member 13 passes through the connecting column 113 and can slide along the connecting column 113.

[0088] In this embodiment, along the first direction Z, the bottom plate 112 and the top plate 111 are arranged opposite to each other, the driving member 13 is located between the bottom plate 112 and the top plate 111, and the top plate 111, the driving member 13 and the bottom plate 112 are connected by a connecting column 113, wherein the top plate 111 and the bottom plate 112 are fixedly connected to the connecting column 113, the driving member 13 passes through the connecting column 113, and can slide along the connecting column 113 between the bottom plate 112 and the top plate 111, and by providing the top plate 111 fixedly connected to the connecting column 113, the maximum sliding stroke of the driving member 13 along the connecting column 113 can be limited to prevent the driving member 13 from falling off.

[0089] In this embodiment, the changing mechanism 1 may include at least two connecting columns 113 arranged at intervals along the second direction X or the third direction Y, so as to improve the stability of the mounting frame 11 structure, and at the same time improve the stability and reliability of the driving member 13 when sliding along the connecting column 113, thereby making the movement of the lifting assembly 12 along the first direction Z more stable.

[0090] In this embodiment, the specific number of the connecting pillars 113 is not limited.

[0091] In a specific embodiment, Figure 7 As shown, the changing mechanism 1 may further include a pressing assembly 14, the pressing assembly 14 includes a pressing member 141 and a pressing bracket 142, the pressing bracket 142 is detachably connected to the mounting frame 11, and please refer to Fig. 9 and Fig.10 The clamping bracket 142 is provided with a second connecting hole 142a extending along the first direction Z, and the clamping member 141 is detachably connected to the clamping bracket 142 via a second connecting member 142b, which passes through the second connecting hole 142a so that the clamping member 141 can move along the second connecting hole 142a.

[0092] In this embodiment, Figure 8As shown, by providing a pressing assembly 14, multiple adjacent membrane electrode assemblies 18 located below the membrane electrode assembly 181 to be replaced can be pressed, so as to facilitate the replacement of the membrane electrode assembly 181 to be replaced. At the same time, by providing a lifting assembly 12 and a pressing assembly 14, during the replacement process, except for the membrane electrode assembly 181 to be replaced, other normal membrane electrode assemblies 18 in the electrolyzer can be subjected to the pressing force to maintain the pressed state, so as to avoid deformation and damage.

[0093] In this embodiment, by providing the second connection hole 142a and the second connection member 142b, it is convenient to realize the detachable connection between the pressing member 141 and the pressing bracket 142, so that after the replacement of the membrane electrode assembly 181 to be replaced is completed, the pressing assembly 14 can be removed, and at the same time, the driving member 13 can press the replaced electrolyzer device to make the replaced electrolyzer device work normally. The second connection hole 142a extends along the first direction Z, so that the pressing member 141 can move along the second connection hole 142a, that is, along the first direction Z, the pressing member 141 can be installed at different positions of the pressing bracket 142, so that the pressing member 141 can be removed between the membrane electrode assemblies 18 at different positions, which is convenient for replacing the membrane electrode assemblies at different positions along the first direction Z, and when there are multiple membrane electrode assemblies 181 to be replaced in the electrolyzer device, the position of the pressing member 141 relative to the pressing bracket 142 can be adjusted, so as to realize the replacement of multiple membrane electrode assemblies 18.

[0094] The second connecting member 142 b may be a screw, so that the pressing member 141 can slide relative to the second connecting hole 142 a while realizing a detachable connection between the pressing member 141 and the pressing bracket 142 .

[0095] In a specific embodiment, Fig.11 As shown, the pressing member 141 includes a second connecting end 141a and a second plugging end 141b connected to each other. The second connecting end 141a is detachably connected to the pressing bracket 142, and the second plugging end 141b is used to be inserted between adjacent stacking members. The cross-section of the pressing member 141 is L-shaped.

[0096] In this embodiment, the cross section of the pressing member 141 is L-shaped, that is, the second connecting end 141a is perpendicular to and connected to the second plug end 141b, so that after the second connecting end 141a is connected to the pressing bracket 142, the second plug end 141b is perpendicular to the pressing bracket 142, so that the second plug end 141b can abut against the top surface of the membrane electrode assembly 18, so that the pressing member 141 can play a pressing role on the adjacent membrane electrode assembly 18 below the membrane electrode assembly 181 to be replaced. In addition, the connection area between the second plug end 141b and the top surface of the membrane electrode assembly 18 is large, which reduces the stress on the membrane electrode assembly 18 during pressing.

[0097] In this embodiment, the thickness of the second connecting end 141a is greater than the thickness of the second plug-in end 141b, and the second plug-in end 141b is wedge-shaped, so that it is easy to insert between the adjacent membrane electrode assemblies 18 during the replacement process. At the same time, the thickness of the second plug-in end 141b is smaller. After the second plug-in end 141b is inserted between the membrane electrode assemblies 18, the deformation caused by the second plug-in end 141b on the adjacent membrane electrode assemblies 18 is smaller, thereby reducing the impact of the second plug-in end 141b on the adjacent membrane electrode assemblies 18 during the insertion process.

[0098] The pressing member 141 may also be provided with a plurality of second ribs 141c, such as Fig.11 As shown, the second rib 141c is located at the connection between the second connecting end 141a and the second plug-in end 141b, which strengthens the connection between the second connecting end 141a and the second plug-in end 141b, extends the service life of the clamping piece 141, avoids deformation of the clamping piece 141 when the membrane electrode assembly 18 is compressed, and improves the clamping effect of the clamping piece 141 on the membrane electrode assembly 18.

[0099] In a specific embodiment, Figure 6 and Fig. 9 As shown, the changing mechanism 1 further includes a first cushion block 15 and a second cushion block 16 , wherein the first cushion block 15 is connected to the bottom wall of the mounting frame 11 , and the second cushion block 16 is connected to the driving member 13 .

[0100] In this embodiment, Fig. 9 As shown, the stroke of the second connection hole 142a on the clamping bracket 142 is limited. When the number of sections of the membrane electrode assembly 18 in the electrolyzer or fuel cell is small or the position of the membrane electrode assembly to be replaced is close to the bottom, and along the first direction Z, the membrane electrode assembly to be replaced is located below the stroke position of the second connection hole 142a, the first cushion block 15 is provided to make the membrane electrode assembly 18 move upward as a whole relative to the clamping bracket 142, so that the position of the membrane electrode assembly to be replaced is adjusted to within the stroke of the second connection hole 142a, so that the clamping assembly 14 can clamp the membrane electrode assembly 18.
