Popis:	The structure, composition, and electrocatalytic properties of the coatings formed on aluminum by ion-beam-assisted deposition of platinum from the plasma of a pulsed arc discharge under conditions where deposited-metal ions are used as deposition-assisting ions are studied. The coating thickness reaches ~30 nm, and the near-surface content of platinum atoms in the coatings is ~2.6 × 1016 cm-2. The electrocatalytic activities of aluminum-based electrodes with the coatings in the reactions of electrochemical oxidation of methanol and ethanol, which form the basis for the principle of operation of low-temperature fuel cells (considered as promising chemical sources of an electric current), are significantly higher than the activity of a platinum electrode.
