Abstract
A method for fabricating a membrane electrode assembly including providing at least one carrier frame having at least one recess; continuous conveying of the carrier frame along a conveying path; applying an adhesive coating to the carrier frame while the carrier frame is conveyed along the conveying path, wherein the adhesive coating applied to the carrier frame at least partially surrounds the recess and wherein the adhesive coating is applied to the carrier frame by an uninterrupted delivery of adhesive from an applicator nozzle of an application device, wherein the applicator nozzle has a passage surface whose geometry is changed during the uninterrupted delivery of the adhesive; and placing a membrane and/or an electrode on the adhesive application.
Claims14
A method for manufacturing a membrane electrode assembly comprising:
- providing at least one carrier frame having at least one recess;
- continuous conveying the carrier frame in a conveying direction;
- applying an adhesive coating to the carrier frame while conveying the carrier frame in the conveying direction, wherein
- the adhesive coating applied to the carrier frame surrounds the recess,
- the adhesive coating is applied to the carrier frame by a continuous delivery of adhesive from an applicator nozzle of an application device, and
- the applicator nozzle is controllable so that the adhesive is dispensed completely around the recess in the carrier frame without being deposited in the recess during the continuous delivery of the adhesive;
- and
- placing a membrane and/or an electrode on the adhesive coating.
An apparatus for manufacturing a membrane electrode assembly comprising:
- a carrier providing device adapted to provide at least one carrier frame for the membrane electrode assembly;
- a conveying device adapted to continuously convey the at least one carrier frame in a conveying direction;
- an application device adapted to apply an adhesive coating encompassing a recess of the carrier frame onto the continuously conveyed carrier frame, wherein
- the application device includes an applicator nozzle that is controlled to apply the adhesive coating so that the adhesive is dispensed completely around the recess in the carrier frame without being deposited in the recess by a continuous delivery of adhesive, and
- the applicator nozzle has a variable passage surface in its geometry during the continuous delivery of the adhesive;
- and
- a first placement device adapted to place a membrane and/or an electrode on the adhesive coating.
