The degradation of nanodimensional platinum catalysts in concentrated phosphoric acid and the related changes in the kinetics of cathodic oxygen reduction have been studied in the course of accelerated corrosion tests. The results of structural and electrochemical investigations showed that the stability of such electrocatalytical systems substantially depends on the type of supporting carbon and the metal phase composition.
