Developing a high-performance membrane electrode assembly (MEA) poses formidable challenge for fuel cells, which lies in achieving both high metal loading and efficient catalytic activity concurrently MEA catalysts. Here, we introduce porous Co@NC carrier to synthesize sub-4 nm PtCo intermetallic nanocrystals, an impressive Pt of 27 wt %. The PtCo–CoNC catalyst demonstrates exceptional remarkable stability the oxygen reduction reaction. Advanced characterization techniques theoretical calculations emphasize synergistic effect between alloys single Co atoms, enhances desorption OH* intermediate. Furthermore, PtCo–CoNC-based cathode delivers power density 1.22 W cm–2 test owing enhanced mass transport, is verified by simulation results O2 distributions current inside layer. This study lays groundwork design catalysts with practical applications cells.

An oxygen reduction reaction (ORR) is the key half of proton exchange membrane fuel cells (PEMFCs), and highly dependent on Pt-based nanocrystals as core electrocatalysts. Despite exceptional ORR activity from adjusting electronic structures surface or near-surface atoms, several serious issues, including corrosion carbon supports, preferential leaching active metal elements, instability low-coordinated atoms sintering/agglomeration nanocrystals, still exist, challenging durability developed catalysts. From point view catalyst structure design, in this review, we summarized state-of-the-art structural regulation strategies for improving The current limitation binary catalysts electrocatalysis firstly discussed, detailed are further classified into optimization metal-doped alloys, core/shell structures, intermetallics high-entropy etc. structure–performance relationship detailedly explained, especially emphasizing elimination above restrictions.
