Elucidating High-Potential Degradation Mechanisms in Proton Exchange Membrane Fuel Cells

Huahui Xu, Jiabin You, Hui Li, Yongjian Su et autres

High-potential states challenge proton exchange membrane fuel cell durability via carbon corrosion. However, the coupling between carbon corrosion and performance loss remains poorly understood. Here, a multiscale cathode catalyst layer (CCL) degradation model is developed, which integrates carbon corrosion, Pt degradation, and …

Simple Synthesis of Ultrasmall Pt5La Nanoalloy for Highly Efficient Oxygen Reduction Reaction

Run Cai, Wenjie Bi, Jiayi Liao, Shuwen Yang et autres

Pt-rare earth metal (Pt-RE) alloys are considered to be one of the most promising electrocatalysts for producing oxygen reduction reactions (ORRs) due to their compressively strained Pt overlayer and their exceptional negative-alloy formation energies, which result in excellent activity and stability. However, …
