Cyclic voltammetry was carried out on electrodes prepared from selected catalyst mate-rials on a rotating-disc electrode. The electrochemically active surface area of the platinumand electrocatalytic activities towards the oxygen-reduction reaction were evaluated from the RDE measurements, in which also the stability towards electrochemical ageing was investigated. These analyses indicated that impregnation by H2PtCl6is the most suitable of the studied catalyst synthesismethods. Mass-specific ORR activities similar to that of commercial reference catalyst are obtained. Catalysts prepared on carbon ExpCB showed greater stability than those based on 350G.
