    摘要： 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

    摘要： A manufacturing method of a proton exchange membrane is provided, which includes the steps as follows. The hydroxyl groups are disposed on the surface of a substrate by a hydrophilic treatment. The hydroxyl groups on the substrate are chemically modified with a coupling agent by a sol-gel process. The substrate is exposed to an amino acid with a phosphonate radical so that the amino acid containing a phosphonate radical can be chemically bonded with the coupling agent. The chemically bonded substrate is immersed in phosphoric acid for absorbing the phosphoric acid. The substrate blended with the phosphoric acid is placed between at least two leak-proof films for the purpose of preventing the leakage of the absorbed phosphoric acid. The proton exchange membrane manufactured by this method enable to retain the phosphoric acid in organic/inorganic complex form and micron/nano complex pore size.

    摘要： A process for manufacturing a reinforced membrane-seal assembly includes: (i) providing a carrier material; (ii) providing a planar reinforcing component having one or more first regions including pores and a second region including pores, the first regions being patches and non-continuous and the second region surrounding the first regions and being continuous; (iii) depositing an ion-conducting component; (iv) drying the ion-conducting component; (v) depositing a seal component; (vi) drying the seal component (vii) removing the carrier material. In embodiments, ion-conducting component fills the pores in the first regions and seal component fills the pores in the second region; steps (ii), (iii) and (v) can be carried out in any order; step (iv) is carried out subsequent to step (iii); step (vi) is carried out subsequent to step (v); and steps (iv) and (vi) are carried out subsequent to step (ii). Also disclosed is an assembly prepared by such process.
