Proton-exchange membrane fuel cells (PEMFCs) serve as a critical technological avenue for the large-scale advancement of renewable energy and attainment goals carbon peak neutrality. However, sluggish oxygen reduction reaction (ORR) at cathode high dependence upon expensive scarce platinum group metal (PGM)-based catalysts are main bottlenecks limiting development PEMFCs. Therefore, non-PGM-based catalysts, especially highly promising single-atom (SACs), has emerged an effective solution to reduce costs. insufficient long-term stability SACs under PEMFC operating conditions severely hampers their practical application. Metal–support interactions (MSI) generally considered strategy enhancing SACs. Consequently, this review explores topic in PEMFCs by constructing single-atom-supported with MSI. In discussion, degradation pathways initially outlined, followed exploration MSI principles, synthesis strategies based on MSI, applications cathodes. Finally, overview is provided regarding challenges future catalysts.

Abstract Atomically dispersed metal and nitrogen co‐doped carbon (MNC) is a promising oxygen reduction reaction (ORR) catalyst for electrochemical energy storage conversion applications but typically suffers from low durability activity under the acidic conditions of practical polymer electrolyte exchange membrane fuel cells (PEMFCs). Recently, performance MNC nanocomposites ORR has been enhanced by exploiting synergistic coupling effects their constituents (single‐atom sites, nanoclusters, nanoparticles). The unique geometric structures formed diverse sites in these provide optimal electronic efficient pathways, thus resulting high long‐term durability. This work provides an overview as electrocatalysts PEMFC conditions, focusing on enhancement methods highlighting strategies used to prepare electrocatalytically containing no or amounts platinum group metals. Progress development advanced catalysts discussed, pivotal role within explored together with characterization elucidate effects. Finally, challenges prospects developing next‐generation are presented. image
