Problems solved by technology
In the roll lamination continuous process, we found that it was difficult to correctly align the lamination position of the catalyst electrode layer due to the difference in the feed speed of the electrode film
[0013] In addition, we found that since the spacing between the catalyst electrode layers is not constant in the process of manufacturing a continuous pattern of catalyst electrode layers by coating the catalyst slurry to the electrode film, the distance between the cathode catalyst electrode layer and the anode catalyst electrode layer Lamination position is difficult to align

Disclosed are an apparatus and method for manufacturing a membrane-electrode assembly of a fuel cell. The apparatus for manufacturing the membrane-electrode assembly for a fuel cell includes: an electrode film sheet unwinder for supplying upper and lower electrode film sheets having upper and lower electrode films with anode and cathode layers along a predetermined transfer path, an electrolyte membrane sheet unwinder that supplies an electrolyte membrane sheet, a driving bonding roll that has an engraved portion and an embossing portion, a driven bonding roll that is to be moved in the vertical direction toward the driving bonding roll, a film rewinder that recovers, by winding, the upper and lower electrode films, and a position aligning unit that aligns the positions of the anode layer and the cathode layer while switching the running directions of the upper and lower electrode film sheets and the upper and lower electrode films.
Description
[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2020-0046617 filed on April 17, 2020, the entire contents of which are hereby incorporated by reference. technical field [0003] The present disclosure relates to systems for fabricating components for fuel cell stacks. More specifically, the present disclosure relates to apparatus and methods for fabricating membrane-electrode assemblies for fuel cells. Background technique [0004] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0005] Fuel cells are known to generate electricity through an electrochemical reaction between hydrogen and oxygen. Even without a separate charging process, a fuel cell can continuously generate electricity after receiving chemical reactants from the outside. [0006] A fuel cell may be formed by disposing separator...
