Definitions

  • the invention relates to an assembly device and a use of the assembly device for the assembly of electrolytic cells in an electrolyzer.
  • An electrolyser is a device that uses electricity to convert substances (electrolysis).
  • electrolysis electrolysis
  • electrolyzers such as an electrolyzer for water electrolysis.
  • a valuable material can be hydrogen, in particular, which is generated with water electrolyzers. So-called EE gas, for example, can be produced using the hydrogen.
  • An electrolyzer usually has a large number of electrolysis cells, which are arranged adjacent to one another. Using water electrolysis, water is broken down into hydrogen and oxygen in the electrolysis cells. In a PEM electrolyser, distilled water is typically fed in as starting material on the anode side and passed to a proton-permeable membrane (“proton exchange membrane”);
  • the individual electrolytic cells are typically stacked to form a segment comprising a large number of individual cells in an axial direction and built into the segment.
  • An electrolyzer usually has a plurality of segments, which together form the so-called electrolysis stack or simply "stack". For example, 50 electrolysis cells can be stacked axially to form a segment and in turn, for example, 5 segments can be stacked to form a stack in the axial direction. so that such an electrolysis stack includes, for example, 250 cells in an overall axial network.
  • the cells In order to make the entire network of cells functional for operation under a desired operating pressure of the electrolyser, the cells must be sealed from one another for the transport of fluids and at the same time good electrical contact with neighboring cells must be guaranteed for the electrical voltage supply across the cells. This is usually achieved by applying an axial force to the cells during assembly of the electrolyser in order to achieve sufficient surface pressure so that both the desired mechanical stress for the fluid-mechanical sealing of the electrolytic stack and the required electrical contact are achieved.
  • very complex and specially configured pressing or clamping devices, assembly aids and monitoring devices are used, which is very expensive.
  • Such a pressing and fixing device is described, for example, in WO 2020/203319 A1 as part of an electrolyzer.
  • a plurality of electrolytic cells of an electrolyzer are densely packed and positioned to form a cell stack in an axial stacking direction.
  • An axial pressing force is applied with a rolyseur's integrated pressing device is applied to the cell stack and the desired pressing force is set and maintained.
  • the pressing device encompasses the entire cell stack.
  • the pressing device has a respective end plate that is movable relative to one another and that also functions as an actuator or counter bearing. As a result, the axial pressure force is effective and this is kept in a fixed state, so that a permanent maintenance of the surface pressure of the cells is achieved.
  • the invention is based on the knowledge that the previously known devices for initial assembly and with a view to later service purposes for mechanical bracing or relaxation of the stacks are very disadvantageous, mainly because of the high costs and the lack of flexibility.
  • electrolysers expected in the future with higher outputs and an increased demand for electrolysers on an industrial scale, there is therefore a great need to overcome these disadvantages and at the same time to enable high operational reliability and flexibility in terms of service and maintenance.
  • This is particularly important in pressure electrolysis with working pressures of around 20-30 bar and beyond.
  • the pressure and fluid-tight mechanical design and electrical wiring of the cells are particularly important here.
  • the invention recognizes and overcomes these disadvantages for the first time in a particularly advantageous manner by proposing a flexible and, above all, separate assembly device as an independent, separate unit and tool during assembly for impressing the necessary axial force component on a preassembled electrolysis stack, and thus a disadvantageous integral one and permanent fixed installation of the mounting device and proposes a detachable connection.
  • a reduction in the complexity of the overall system is achieved here and installation space or installation length of the system is saved, which in turn brings cost advantages.
  • the assembly device no longer has to remain on the electrolyser as an integral part of the system.
  • the assembly device according to the invention can thus be used several times during the initial production and setting of the desired mechanical pressure of a large number of electrolysis stacks. Multiple use is a great cost advantage given the large quantities to be expected in the future in series production of electrolysers.
  • the assembly device is easy to transport and, if necessary, can be mechanically connected to another electrolyser. This enables use of the assembly device during service in order to be able to carry out inspection work and settings.
  • the application of the axial force component is achieved by the hydraulic assembly.
  • the hydraulic pressure of the hydraulic assembly serves as a direct signal of the state of tension or the necessary axial force to achieve the desired surface pressure, which can be set precisely and reproducibly as well as with a high level of reliability and quality.
  • the actuator applies the hydraulically induced compressive force in the axial direction against the electrolysis stack and compresses it axially in order to achieve the desired surface pressure . This creates the overall network the multiplicity of cells in the electrolysis stack for operation under a desired operating pressure of the electrolysis system.
  • This state of tension of the electrolysis stack can be fixed in the electrolysis stack by means of suitable screwing or fixing elements and the recordings or the connecting elements of the recording of the assembly device can then be released again in order to remove the assembly device from the electrolysis stack.
  • the assembly device does not have to permanently ensure that the surface pressure is maintained and does not need to remain on the stack. It can be used for other purposes of this type, ie the assembly device can be used for adjustment work during the initial assembly and commissioning of electrolysers and for service and maintenance of existing electrolysers.
  • the assembly device is in particular for the assembly of an electrolyser with a number of electrolysis cells stacked in the axial direction to one another by means of a centering rod to form an electrolysis stack and can be used for detachable attachment and pressing.
  • the centering linkage usually has a number of axially parallel rods which are arranged at the periphery of the electrolysis stack—preferably symmetrically—so that precise engagement and, if necessary, attachment of the assembly device can be achieved.
  • the coupling via the connecting elements on the periphery of the pressure plate facilitates access and handling considerably and thus the assembly, operational use and simple disassembly after the desired pressure has been applied.
  • a flexible adjustment to different geometries of the respective centering linkage is possible with the assembly device
  • the receptacle therefore advantageously has a number of connecting elements arranged on the periphery of the pressure plate in accordance with the configuration of the electrolysis stack.

  • the cells of the electrolysis stack are thus sealed off from one another for the transport of pressurized fluids and at the same time good electrical contact is ensured between neighboring cells and the electrical voltage supply via the cells during operation.
  • This is of particular advantage when used in pressure electrolysers with high operating pressures of around 20 - 30 bar and beyond.
  • the use of the assembly device with the detachable hydraulic assembly achieves a particularly compact design of the electrolyzer, which saves installation space and thus costs.
