Atomically dispersed ZnNC catalysts with Zn-Pyrrolic-N₄ moieties have been synthesized, and the ZnNC-based anion-exchange membrane fuel cell not only presents an ultrahigh peak power density of 1.63 W cm⁻² but also a long-term durability with more than 100 h operations in H₂-O₂ system. Density functional calculation further reveals that the Zn-Pyrrolic-N₄ structure is the origin of high activity of as-synthesized ZnNC catalyst.
