Abstract (en)
[origin: WO2005023914A2] The invention relates to a polymer membrane that is coated with a catalyst layer, said polymer membrane comprising phosphonic acid polymers. Said polymers are obtainable by polymerization of phosphonic acid monomers. The invention is characterized in that the catalyst layer comprises phosphonic acid ionomers, said ionomers being obtainable by polymerization of phosphonic acid monomers.
