Abstract (en)
[origin: WO2022058260A1] The invention relates to a method for producing a catalyst-coated membrane (CCM), having the steps of: producing and/or providing at least one first ink (16) with a first ink composition, comprising supported catalyst particles (13), a proton-conductive ionomer (15), and a dispersing agent, the content of supported catalyst particles (13) in the composition remaining below the content of the proton-conductive ionomer (15); unwinding a web-shaped proton-conductive membrane material (20) which is provided on a roll (22); applying at least one layer of the first ink (16) onto at least one section of the membrane material (20) using a first application tool (17); and sputtering a catalyst powder consisting of or comprising catalyst particles (13) onto the outermost ink layer facing away from the membrane material (20) using a sputtering device (29).
