Abstract The commercialization of fuel cell technologies requires a significant reduction in the amount of expensive platinum catalyst in the cathode while still maintaining high catalytic activity and stability. Herein a cost‐effective, highly durable, and efficient catalyst consisting of ordered Fe 3 Pt nanoparticles supported by mesoporous Ti 0.5 Cr 0.5 N (Fe 3 Pt/Ti 0.5 Cr 0.5 N) is demonstrated. The Fe 3 Pt/Ti 0.5 Cr 0.5 N catalyst exhibits a five‐fold increase in mass activity relative to a Pt/C catalyst at 0.9 V for the oxygen reduction reaction. More importantly, the catalyst shows a minimal loss of activity after 5000 potential cycles (9.7%). The enhanced activity of the ordered Fe 3 Pt/Ti 0.5 Cr 0.5 N catalyst, in combination with its enhanced stability, makes it very promising for the development of new cathode catalysts for fuel cells.
