A significant decrease in performance was observed for commercial Pt/C due to electrochemical oxidation of the carbon support and subsequent detachment and agglomeration of Pt particles. The Pt/TiO2 cathode catalyst exhibited excellent fuel cell performance and ultrahigh stability under accelerated stress test conditions and can be considered as a promising alternative for improving the reliability and durability of PEMFCs.
