RDE polarization curves of (a) G-CNT 100/20 and (b) Pt/C after the 1st, 1000th, 3000th, 5000th and 8000th in an O2-saturated 0.1 M KOH solution; RDE polarization curves of (c) G-CNT 100/20 and (d) Pt/C in an O2-saturated 0.1 M KOH solution with or without 0.5 M methanol.

G-CNT 100/20 exhibits a dramatically improved tolerance to methanol poisoning compared with Pt/C.
