Summary: We demonstrate that the electrochemically corroded thick nitrogen-doped carbon (N-C) layer encapsulated Pt/C catalyst exhibits high activity and ultrahigh stability for methanol oxidation and oxygen reduction reactions. The encapsulation of thick N-C layers initially results in low activity, but after an aging corrosion process, the activities increase significantly and remain stable. The catalyst also shows high power densities and maintains stability in an acidic membrane fuel cell. The corrosion of the thick N-C layer leads to the formation of micropores, which enhance mass transport and protect Pt particles, thereby improving activity and stability.
