Overview

This research demonstrates improved oxygen reduction activity in fuel cell catalysts using dual-atom-site-rich supports, indicating effective performance enhancement.

Key Points

Investigate how dual-atom-site-rich carbon supports influence the performance of PtZn catalysts in fuel cells.
Comparison of single-atom-site-rich supports versus dual-atom-site-rich supports for PtZn intermetallic nanoparticles.
Utilization of density functional theory calculations to analyze electronic interactions.
Conducting rotating disc electrode tests to measure mass activity and membrane electrode assembly tests for power density.
PtZn@CoFe-NC catalyst shows a mass activity of 1.93 A mg Pt −1 at 0.9 V vs. RHE.
Achieves peak power density of 2.18 W cm −2 in H2-O2 tests.
Retains approximately 95% performance after 30,000 accelerated stress test cycles.
