Overview

Incorporation of chloride improves oxygen reduction in perovskite oxides, suggesting enhanced fuel cell performance.

Key Points

  • Catalysis increases by 3–5 fold due to chloride incorporation in perovskite oxides, enhancing oxygen reduction.
  • Enhanced performance and durability are observed at 750 °C with only 2.7% degradation over 100 hours in fuel cells.
  • Analysis reveals a new mechanism for tailoring perovskite microchemistry that improves ionic transport and reaction dynamics.
  • This approach highlights the potential for new strategies to design advanced fuel cell oxygen electrodes.
