Oxygen Reduction Electrocatalysts toward Practical Fuel Cells: Progress and Perspectives

Shahid Zaman et al.

Summary: Fuel cells show great potential as a renewable energy technology, but face challenges due to high cost and poor reliability of cathodic electrocatalysts for the oxygen reduction reaction (ORR). This review emphasizes recent progress of ORR electrocatalysts in fuel cells and highlights issues with activity translation from laboratory testing to practical applications. Future efforts should focus on large-scale preparation, unified assessment criteria, advanced interpretation techniques, advanced simulation and artificial intelligence to advance efficient ORR electrocatalysts in fuel cells.

Insights on platinum-carbon catalyst degradation mechanism for oxygen reduction reaction in acidic and alkaline media

Marc Francis Labata et al.

Summary: This study investigates the degradation mechanisms of platinum-carbon catalyst in both acidic and alkaline media via potential cycling. High potential cycling in acid leads to carbon surface oxide formation and severe ORR activity loss, while in alkaline it causes carbon layer dissolution and Pt agglomeration. These findings offer insights for developing mitigation strategies for stable fuel cell operation.

Unveiling the Nature of Pt Single-Atom Catalyst during Electrocatalytic Hydrogen Evolution and Oxygen Reduction Reactions

Junjie Li et al.

Summary: This study achieves high loading of Pt single atoms on carbon nanosheets through atomic layer deposition and investigates the activity of Pt single atoms and nanoparticles using operando X-ray absorption spectroscopy in the hydrogen evolution reaction and oxygen reduction reaction. The results reveal differences in the unoccupied density of states of Pt 5d orbitals between Pt single atoms and nanoparticles, as well as the formation of a stable Pt oxide during ORR on the Pt-1/NCNS catalyst.
