MUMBAI, India, Aug. 17 -- Intellectual Property India has published a patent application (202627069684 A) filed by Carl Freudenberg Kg on June 03, 2026, for Proton-Exchange Membrane Fuel Cell With Improved Contact Between The Gas Diffusion Layer And The Polymer-Electrolyte Membrane.
Inventors include Bock, Achim; Klein, Kristof; Rakousky, Christoph; Barsch, Hannes; Von Spee, Amlie; and Lble, Matthias.
The application for the patent was published on August 14, 2026, under issue no. 33/2026.
Abstract: The invention relates to a proton-exchange membrane fuel cell with improved contact properties between the gas diffusion layers (GDL) and the catalyst-coated polymer-electrolyte membrane (CCM), to a gas diffusion layer, to a method for producing a gas diffusion layer, and to a method for producing a proton-exchange membrane fuel cell which exhibits an improved contact at the boundary surface between the gas diffusion layers and the catalyst-coated polymer-electrolyte membrane. The gas diffusion layer comprises a carbon fiber nonwoven material or a carbon fiber paper comprising carbon fibers which have a main orientation direction with respect to the base surface of the nonwoven material or paper, said main orientation direction not being parallel to the main orientation of the channels of an adjacent flow distributor plate.
