Definitions
- a method and a device for producing a membrane electrode assembly for example a membrane electrode assembly for a fuel cell, are described here.
- a known method for producing a membrane-electrode assembly for a fuel cell is the pick-and-place method.
- robots or grippers arranged on rails can be used, which can execute movements in different spatial directions in order to place the different components of the respective membrane-electrode assembly with the required accuracy.
- Such a pick-and-place method for producing membrane-electrode assemblies and fuel cells in large series is demanding with regard to the material costs and also because of the required handling of the filigree and dirt-sensitive components.
- a carrier for a membrane and/or an electrode as part of a continuous web of material.
- the web of material can pass through a plurality of processing stations, with a second component of the membrane-electrode arrangement being connected to the carrier.
- Such a method is disclosed, for example, by the document DE 10 2015 010 440 A1.
- a disadvantage of known production methods for membrane electrode assemblies with at least initially continuous webs of material is that an adhesive or bonding agent, which connects the components to one another, cannot be applied continuously to the webs of material.
- a layer of adhesive or adhesive is applied to one of the webs of material, usually a backing, by a stencil or flatbed screen printing process.
- the adhesive or bonding agent can also be applied to a continuously moving carrier layer using a plurality of dispensing nozzles.
- the carrier layer for producing a membrane-electrode assembly must always have at least one recess, which is to be bordered by the adhesive or adhesive to be applied, however, several dispensing nozzles are required to produce an adhesive frame, which are each individually controlled and cyclically activated and deactivated must in order to produce an adhesive frame surrounding the recess on the continuously conveyed carrier layer.
- the plurality of dispensing nozzles In order to ensure a uniform thickness or thickness of the adhesive on the carrier layer, the plurality of dispensing nozzles must also be connected to different feed devices, which supply an amount of adhesive or adhesive corresponding to the intended dispensing quantity of the individual nozzles.
- a method for producing a membrane electrode assembly comprises the steps:
- an adhesive coating to the carrier frame while the carrier frame is being conveyed along the conveying path, the adhesive coating applied to the carrier frame at least partially encompassing/enclosing/forming the first recess and the adhesive coating by an uninterrupted/uninterrupted release of adhesive from an applicator nozzle of a Application device on the support frame is applied, the applicator nozzle having a passage surface whose geometry is changed during the uninterrupted dispensing of the adhesive;
- the adhesive can be, for example, an adhesive that is suitable for fixing a membrane or electrode on the support frame.
- the membrane within the meaning of this method can in particular be a catalyst-coated membrane (CCM) for a membrane-electrode assembly, in particular for a membrane-electrode assembly for a fuel cell.
- CCM catalyst-coated membrane
- the electrode can be either an anode or a cathode, in particular an anode or a cathode in the form of a gas diffusion layer, GDL.
- the at least one carrier frame can optionally be provided as a section of a carrier substrate, in particular a quasi-endless carrier substrate.
- the carrier substrate can be provided as a roll of material that can be unrolled from a roll.

- the membrane or electrode web material can also optionally be provided as roll material that can be unrolled from a roll.
- the first recess in the carrier frame can be produced, for example, with a stamping process or with a milling process, just like any other recesses in the carrier frame.
- the manufacturing method can include at least one of the following steps: - arranging a catalyst-coated membrane on the first electrode; and or
- the catalyst coated membrane may be at least partially enclosed by the electrode and support frame and/or by the adhesive pad by placing the electrode on the adhesive pad.
- a device for producing a membrane electrode assembly includes a carrier supply device, which is set up to provide at least one carrier frame for a membrane electrode assembly and a conveyor device, which is set up to continuously convey the at least one carrier frame along a conveying path.
- An application device with an applicator nozzle is set up to apply an adhesive coating, which at least partially forms, encompasses or surrounds a first recess in the carrier frame, to the continuously conveyed carrier frame, with the application device also being set up to apply the adhesive coating by means of an uninterrupted/uninterrupted release of adhesive from the Apply applicator nozzle.
- the applicator nozzle has a passage surface that is variable in its geometry during the uninterrupted dispensing of adhesive.
- the applicator nozzle can be a slit nozzle.
- the application device can have an outlet mask, for example, which is set up to at least temporarily close at least part of an outlet opening of the applicator nozzle during the dispensing of the adhesive and/or to change, in particular to reduce, the geometry of the passage area of the applicator nozzle.
- a partial closing of the outlet opening of the applicator nozzle with the outlet mask causes, for example, a reduction in the passage area of the applicator nozzle.
- the applicator nozzle can be used to apply adhesive to a continuously conveyed carrier frame without interruption.
- the outlet mask which temporarily closes and/or opens again part of the outlet opening of the applicator nozzle during the dispensing of the adhesive and/or changes the geometry of the passage surface of the applicator nozzle, makes it possible to create a recess in the adhesive coating.
- an adhesive coating can be produced/applied that at least partially or completely reshapes/surrounds/encloses the carrier frame without the continuous conveyance of the carrier frame having to be interrupted for this purpose.
- Enclosing the recess with the adhesive coating means that the adhesive coating on the surface of the carrier frame has at least one recess which at least partially surrounds/borders/forms the recess in the carrier frame. If the recess in the adhesive coating is completely surrounded, surrounded or surrounded by the adhesive coating, so that the recess in the carrier frame is also completely surrounded or bordered by the adhesive coating on the carrier frame, the adhesive coating on the carrier frame completely encompasses the recess in the carrier frame.
- the thickness, height and/or thickness of the respective adhesive coating can be influenced by controlling and/or regulating the supply of adhesive to the applicator nozzle and, in particular, can be made constant and/or uniform.
- the supply of adhesive to the applicator nozzle can be reduced, for example for the duration of the temporary closure of part of the applicator nozzle by the outlet mask and/or for the duration of a temporary change in geometry of the passage area.
- an adhesive layer applied through a partially closed applicator nozzle can have the same thickness/thickness/height as part of the adhesive layer that was applied by a completely unclosed applicator nozzle with an unchanged geometry of the passage area.
- a first placement device is configured to place a first membrane and/or a first electrode on the adhesive pad.
- the membrane can in particular be a catalyst-coated membrane (CCM) for a membrane-electrode assembly, in particular for a membrane-electrode assembly for a fuel cell.

- the first placement device may further be configured to place the first electrode with the catalyst coated membrane placed thereon on the adhesive backing.
- the catalyst-coated membrane can be partially or completely arranged in the first recess of the support frame.
- the first arrangement device can also be set up for this be to place the electrode on the adhesive pad such that the catalyst coated membrane is at least partially enclosed/enclosed by the electrode and the support frame and/or the adhesive pad.
- the first placement device may be configured to place the electrode on the adhesive pad such that the catalyst-coated membrane is placed between the first electrode and the support frame.
- a catalyst-coated membrane can be arranged on the first electrode and that, in a second production step, the first electrode together with the membrane arranged thereon can be placed on the carrier frame and/or the membrane applied to the carrier frame Adhesive coating can be arranged.
- Adhesive coating can be arranged. This makes it easier to manufacture the membrane electrode assembly and at the same time increases manufacturing accuracy. Furthermore, compared to a sequential arrangement of the membrane and the first electrode, this can reduce the length of a production line for a membrane-electrode assembly.
- the electrode and/or the membrane can each be provided as electrode or membrane sections or as a continuous sheet material and/or arranged as electrode or membrane sections or as a continuous sheet material on one another and/or on the adhesive coating.
- the first and/or the second arrangement device can each have one or more vacuum drums, which are set up in particular for non-slip handling of the conveyed carrier frames and/or membranes and/or electrodes.
- the device can also include an inflow controller which is set up to influence the amount of adhesive supplied to the application device and thereby to determine the thickness or thickness of the adhesive coating. Furthermore, the inflow controller can also be set up to determine a beginning and/or an end of the dispensing of the adhesive by the application device.
- the inflow regulator can in particular be set up to influence/regulate the amount of adhesive supplied to the application device in such a way that the adhesive coating applied with the applicator nozzle always has the same thickness or depth.
- the inflow regulator can be set up to influence/regulate the quantity of adhesive supplied to the application device in such a way that a partial closure at times and/or complete opening of the applicator nozzle at times by the outlet mask or a change in the Geometry of the passage area of the applicator nozzle, the thickness or the thickness of the adhesive coating applied with the applicator nozzle does not change or is not influenced.
- a control of the outlet mask which controls a temporary partial closing and/or a temporary complete release of the applicator nozzle through the outlet mask, can be coupled to the inflow controller.
- the inflow regulator can reduce the amount of adhesive supplied to the application device with the applicator nozzle when the outlet mask closes at least part of the exit opening of the applicator nozzle during the dispensing of the adhesive.
- the inflow regulator can increase the amount of adhesive supplied to the application device with the applicator nozzle if the outlet mask does not close the outlet opening of the applicator nozzle during the dispensing of the adhesive.
- An advantage here is that the thickness or thickness of the coating of adhesive applied with the applicator nozzle can be made constant on the carrier frame without the need to control, move, change or influence the applicator nozzle as such. Furthermore, on the one hand, complex geometries can be realized for the adhesive coating and, on the other hand, the construction of the application device can be simplified and designed to be particularly error-free.
- an adhesive coating with a flat contact surface for the membrane and/or Electrode are produced, which in particular has no depressions between individual adhesive or adhesive beads. The occurrence of unintentional air inclusions between the carrier frame and the membrane and/or electrode when the same are arranged on one another can thus be avoided.
