Nonmetal hybridization of interstitial sites in platinum high entropy alloys yields exceptional catalytic activity, creating robust catalysts for practical fuel cell devices.
State-of-the-art durability and oxygen reduction activity occur in nitrogen-doped alloys at both material and membrane electrode assembly levels, surpassing baseline catalysts.
Generic synthesis simultaneously incorporates light nonmetals into high entropy alloys, supporting the creation of durable mass transport networks for ultralow-platinum fuel cells.
