Abstract: A catalytic composition for producing a fuel cell electrode comprises a catalytically active material in particulate form, for example platinum, a carbon nanomaterial which is coated with a first ionomer, as well as a binding agent composition in which the catalytically active material and the coated carbon nanomaterial are present in dispersed form, wherein the binding agent composition comprises a second ionomer and the first and second ionomers are the same or different. The composition is used to produce a catalytic layer of a fuel cell electrode for a fuel cell.
