Özet

Besides producing clean energy via fuel cells, the costs and activations of catalysts have a great importance. In order to reduce cathode activation losses due to comparably sluggish kinetics of oxygen reduction reaction (ORR), more active catalysts than Pt should be used. Mostly, noble metals are alloyed with second or third metal as cathode catalysts in order to obtain a synergistic effect.
