Abstract
The disclosure relates to a supported catalyst material for a fuel cell. This comprises an electrically conductive, carbon-based carrier material and catalytic structures deposited or grown on the carrier material with a multilayer structure. The core layer comprises an electrically conductive bulk material, with the bulk material in direct contact with the carbon-based carrier material. The thin surface layer has a catalytically active noble metal or an alloy thereof. The preparation is carried out directly onto the carrier material with the deposition of the corresponding starting materials from the gas phase.
