Popis:	In this paper, we study the electrocatalytic activity and stability of materials in the Pt/Ti1 – xRuxO2 – δ system, in oxygen electroreduction reactions, including under operating conditions in a fuel cell (FC). All the obtained electrocatalytic materials are shown to be stable in the electrode potential range of operation of a hydrogen-air FC, while the electroreduction of oxygen proceeds mainly by a four-electron mechanism. The power characteristics of the FC with the obtained electrocatalyst are comparable to those of a FC with a commercial electrocatalyst, while the stability of the obtained electrocatalysts is 5–6 times higher than that of Pt/C catalysts.
