Nitrogen‐enriched core–shell structured Fe/Fe3C–C (N–Fe/Fe3C@C) nanorods have been successfully synthesized and demonstrated as promising oxygen reduction reaction catalysts with high activity and improved kinetics. The N–Fe/Fe3C@C nanorods, when used as cathode catalysts in microbial fuel cells, outperform the commercial Pt/C‐based cathode at the maximum power output. Both N‐dopant and core–Fe3C are believed to play key roles for the improved catalytic performance of N–Fe/Fe3C@C. Notably, the N–Fe/Fe3C@C features an ultra‐low cost and excellent long‐term stability, as discussed by X. L. Feng, Z. He, J. H. Chen and co‐workers on page 1399. <blockFixed type="graphic"> <mediaResourceGroup> <medi
