Abstract

The present disclosure relates to a packaging arrangement comprising a base plate, at least one first bolt secured to the base plate and a multiplicity of separator plates for an electrochemical system, which are stacked on the base plate in a stacking direction so as to form a separator plate stack, wherein the first bolt is received in first cut-outs of the stacked separator plates, said first cut-outs being aligned in the stacking direction. The present disclosure further relates to a packaging system including a light-load carrier and two of the aforementioned packaging arrangements, and to a method for packaging separator plates for an electrochemical system.

First claim

1 . A packaging arrangement comprising a base plate, at least one first bolt secured to the base plate and a multiplicity of separator plates for an electrochemical system, which are stacked on the base plate in a stacking direction so as to form a separator plate stack, wherein the first bolt is received in first cut-outs of the stacked separator plates, said first cut-outs being aligned in the stacking direction.

2 . The packaging arrangement according to claim 1 , comprising at least one second bolt secured to the base plate, wherein the second bolt is received in second cut-outs of the stacked separator plates, said second cut-outs being aligned in the stacking direction.

3 . The packaging arrangement according to claim 2 , wherein the first bolt and the second bolt fix the separator plate stack in position relative to the base plate in a first direction perpendicular to the stacking direction and in a second direction perpendicular to the stacking direction and perpendicular to the first direction.

4 . The packaging arrangement according to claim 2 , wherein the separator plates have a rectangular or substantially rectangular shape perpendicularly to the stacking direction, wherein the first cut-outs and the second cut-outs of the separator plates are formed in diagonally opposing corner regions of the separator plates.

5 . The packaging arrangement according to claim 2 , comprising a cover plate, wherein the separator plate stack is arranged between the base plate and the cover plate in the stacking direction.

6 . The packaging arrangement according to claim 5 , wherein the cover plate has a first cut-out, which is aligned with the first cut-outs of the separator plates in the stacking direction, and wherein the cover plate has at least one second cut-out, which is aligned with the second cut-outs of the separator plates in the stacking direction, wherein the first bolt is additionally received in the first cut-out of the cover plate and wherein the second bolt is additionally received in the second cut-out of the cover plate.

7 . The packaging arrangement according to claim 1 , wherein corner regions of the base plate protrude beyond corner regions of the separator plate stack and/or corner regions of the cover plate protrude beyond corner regions of the separator plate stack.

8 . The packaging arrangement according to claim 5 , comprising a flexible film which encloses the base plate, the separator plate stack and the cover plate at least in some regions.

9 . The packaging arrangement according to claim 5 , comprising at least one tape which encircles the base plate, the cover plate and the separator plate stack at least in some regions.

10 . The packaging arrangement according to claim 8 , wherein the flexible film is formed as shrink film.

11 . The packaging arrangement according to claim 8 , comprising a tear strip, integrated in the flexible film, for opening and/or removing the flexible film.

12 . The packaging arrangement according to claim 1 , wherein the first and/or the second cut-outs of the separator plates are formed as through-holes spaced apart from edges of the separator plates.

13 . The packaging arrangement according to claim 1 , wherein the separator plates each have an active region having structures for conducting media along a planar face of the separator plate and an integrally closed sealing arrangement, encircling the active region, for sealing the active region, wherein the first cut-outs and/or the second cut-outs of the separator plates are each arranged outside the sealing arrangement.

14 . The packaging arrangement according to claim 1 , wherein the separator plates each have an active region having structures for conducting media along a planar face of the separator plate and an integrally closed sealing arrangement, encircling the active region, for sealing the active region, wherein the base plate has at least one through-opening arranged such that a projection of the through-opening onto the separator plates in the stacking direction coincides with the active regions of the separator plates at least in some regions.

15 . The packaging arrangement according to claim 1 , wherein the base plate protrudes beyond the separator plate stack at least in some regions at opposite ends of the separator plate stack in a first direction perpendicular to the stacking direction, and wherein the base plate protrudes beyond the separator plate stack at least in some regions at opposite ends of the separator plate stack in a second direction perpendicular to the stacking direction and perpendicular to the first direction.

16 . The packaging arrangement according to claim 15 , wherein in each case the base plate has a handle, or a structure for receiving a gripping tool, in two of the regions that protrude beyond the separator plate stack at opposite ends of the separator plate stack.

17 . The packaging arrangement according to claim 1 , wherein the separator plates are formed from metal sheets having a sheet thickness of at most 0.5 mm.

18 . A packaging system comprising a light-load carrier and at least two the packaging arrangements according to claim 1 , which are received in the light-load carrier, wherein the light-load carrier and the base plates of the packaging arrangements are dimensioned such that the base plates are received in the light-load carrier next to one another in a form-fitting or substantially form-fitting manner.

19 . A method for packaging separator plates for an electrochemical system, for example to form the packaging arrangement according to claim 1 , the method comprising the steps of:
stacking a multiplicity of separator plates for an electrochemical system on a base plate in such a way that at least one bolt secured to the base plate is received in cut-outs of the stacked separator plates, said cut-outs being aligned in a stacking direction.

20 . The method according to claim 19 , wherein the stacking of the separator plates on the base plate comprises stacking the separator plates on a lifting and lowering device, which reaches through a through-opening in the base plate and is movable in the stacking direction, and lowering the lifting and lowering device or the method further comprising:
arranging a cover plate on the separator plate stack in such a way that the separator plate stack is arranged between the base plate and the cover plate in the stacking direction, and enclosing or encircling the base plate, the separator plate stack and the cover plate using a flexible film or at least one tape that restrains the separator plate stack between the base plate and the cover plate.
