摘要：
A catalyst material comprising an electrically conducting support material, a proton-conducting, acid-doped polymer based on a polyazole salt, and a catalytically active material. A process for preparing the catalyst material. A catalyst material prepared by the process of the invention. A catalyst ink comprising the catalyst material of the invention and a solvent. A catalyst-coated membrane (CCM) comprising a polymer electrolyte membrane and also catalytically active layers comprising a catalyst material of the present invention. A gas diffusion electrode (GDE) comprising a gas diffusion layer and a catalytically active layer comprising a catalyst material of the invention. A membrane-electrode assembly (MEA) comprising a polymer electrolyte membrane, catalytically active layers comprising a catalyst material of the invention, and gas diffusion layers. And a fuel cell comprising a membrane-electrode assembly of the present invention.
