Fe-N-C interfacial engineering on commercial Pt/C catalysts, via unique 5d-3d/2p orbital hybridization, enables a breakthrough in fuel cell durability and performance. The engineered PtFe/C@Fe-N-C catalyst maintains 97.3% of its activity after 30,000 accelerated stress cycles. This exceptional stability and its high mass activity decisively surpass both the performance of pristine Pt/C and the U.S. Department of Energy's 2025 technical targets.
