  • Publication number: 20230282858
    Abstract: A method for producing a catalyst-coated membrane includes: preparing and/or providing a first ink having a first ink composition, comprising substrated catalyst particles proton-conducting ionomer and dispersing agent, in which the fraction of the substrated catalyst particles remains behind the fraction of the proton-conducting ionomer; preparing and/or providing at least one second ink having a second ink composition, comprising the substrated catalyst particles, the proton-conducting ionomer and the dispersing agent, in which the fraction of the proton-conducting ionomer remains behind the fraction of the substrated catalyst particles, unwinding a weblike proton-conducting membrane material provided on a roll; applying at least one layer of the first ink with a first application tool onto at least one section of the membrane material; and applying at least one layer of the second ink with a second application tool onto an outermost layer of the first ink deposited onto the membrane material

  • Publication number: 20230238543
    Abstract: A method for producing a catalyst-coated membrane includes: producing and/or providing at least one first ink with a first ink composition, comprising supported catalyst particles, a proton-conductive ionomer, and a dispersing agent, the content of the supported catalyst particles in the composition remaining below the content of the proton-conductive ionomer; unwinding a web-shaped proton-conductive membrane material which is provided on a roll; applying at least one layer of the first ink onto at least one section of the membrane material using a first application tool; and sputtering a catalyst powder consisting of or comprising catalyst particles onto a surface of the outermost ink layer facing away from the membrane material using a sputtering device.
