Nature Communications, Published online: 04 June 2026; doi:10.1038/s41467-026-73971-8 The heavy use of platinum catalysts limits the large-scale deployment of proton exchange membrane fuel cells. Here, the authors report a carbon support design with small mesopore-dominated structures and moderate pore depth that improves performance at low platinum loading.
