Complex Alloys Enhance Fuel Cell Efficiency Through Improved Oxygen Reduction
Researchers have developed non-metal-hybridized platinum-based compositionally complex alloys to enhance the efficiency of oxygen reduction reactions in fuel cells. The study highlights the role of these alloys in reducing mass transport resistance, a critical factor affecting fuel cell performance. By optimizing the local Pt-ionomer-water interface, the new catalyst demonstrates improved oxygen penetration and reduced local impedance. This advancement could lead to more efficient and durable fuel cells, contributing to the development of sustainable energy technologies.
