A method for creping paper includes applying an adhesive composition to an outer surface of a creping cylinder (Yankee cylinder) to form an adhesive coating, contacting paper with the adhesive coating, removing the paper and adhesive coating from the creping cylinder, and determining a quality of the adhesive coating. Determining the quality of the adhesive coating may include measuring a degree of cross-linking of the adhesive polymer, a concentration of the adhesive polymer in the adhesive coating, a water content of the adhesive coating, an ash content of the adhesive coating, or combinations thereof. Determining the quality of the adhesive coating may also include determining a thickness of the adhesive coating by measuring light absorbed by the coating and calculating the thickness using Beer's Law. Systems and apparatuses for determining the quality of the adhesive coating and for creping paper are also disclosed.

METHOD FOR PRODUCING A GREEN PAPER FOR PRODUCING A GAS DIFFUSION LAYER FOR A FUEL CELL
20230411632 · 2023-12-21 ·

A method is provided for producing a green paper for producing a gas diffusion layer (GDL) for a fuel cell. A use is described of an accordingly produced gas diffusion layer (GDL) in a fuel cell. A first paper web is loaded with metal powder and/or metal fibers, and a microporous layer (MPL) is in the form of at least one coating is applied onto the paper web. The paper web is then subjected to a binder removal process, a sintering process, a coating process, atomic layer deposition (ALD) using thermal ALD methods, and optionally additional process steps in order to obtain the final GDL. After the sintering process, all of the organic components of the green paper are pyrolyzed and thus no longer contained in the GDL, and the GDL consists virtually exclusively of a metal framework.
