Fuel cells are an incredibly powerful renewable energy technology, but their broad applications remains lagging because of the high cost and poor reliability of cathodic electrocatalysts for the oxygen reduction reaction (ORR). This review focuses on the recent progress of ORR electrocatalysts in fuel cells. More importantly, it highlights the fundamental problems associated with the insufficient activity translation from rotating disk electrode to membrane electrode assembly in the fuel cells. Finally, for the atomic-level in-depth information on ORR catalysts in fuel cells, potential perspectives are suggested, including large-scale preparation, unified assessment criteria, advanced interpretation techniques, advanced simulation and artificial intelligence. This review aims to provide valuable insights into the fundamental science and technical engineering for efficient ORR electrocatalysts in fuel cells.
燃料电池是一种极具潜力的可再生能源技术，但其广泛应用仍滞后不前，原因在于用于氧还原反应（ORR）的阴极电催化剂成本高昂且可靠性欠佳。本综述聚焦于燃料电池中ORR电催化剂的近期进展。更重要的是，它突出了燃料电池中从旋转圆盘电极到膜电极组件活性转换不足所关联的根本问题。最后，针对燃料电池中ORR催化剂的原子级深度信息，提出了潜在的展望，包括大规模制备、统一评估标准、先进的解释技术、先进的模拟和人工智能。本综述旨在为燃料电池中高效ORR电催化剂的基础科学和技术工程提供有价值的见解。
