In this paper, we describe a highly stable cathode containing a Pt catalyst supported on an indium tin
oxide (ITO) and carbon nanotube (CNT) composite. The dependence of cathode performance and
durability on the ITO content and the diameter of the CNTs were investigated by electrochemical
techniques. The cathode with 30 wt% ITO and CNTs with diameters 10–20 nm in the composite offered
preferred locations for Pt stabilization and was very resistant to carbon corrosion (i.e., 82.7% ESA
retention and 105.7% mass activity retention after an accelerated stress test for 400 h).
