Abstract

Electrocatalyst which are formed of a carbon support, which is a carbon black with an H content of >4000 ppm and, as the catalytically active component, platinum or bi- or multi-metallically doped or alloyed platinum. The electrocatalysts are prepared by deposition of noble metals on the carbon black surface. They can be used for the production of fuel cells.
