How to Chemically Protect PFAS‐Free Membranes in Fuel Cells: Radical Quenching Poly(vinylphosphonic acid) Layer

Advanced Functional Materials, EarlyView.
Hydrocarbon membranes are a greener alternative to PFSA in PEM fuel cells, but degrade rapidly from radical attack. We present a novel strategy using poly(vinylphosphonic acid) (PVPA) as a local radical scavenger. Incorporated as an interfacial barrier, PVPA enhances chemical stability and significantly extends membrane lifetime under accelerated ...

Ultra‐Thin Hybrid Ion Exchange Interlayer for High Performance Aqueous Zn Metal Batteries

Advanced Science, EarlyView.
An ultra‐thin SPEEK/FCD ion‐exchange interlayer modulates the Zn2+ solvation environment (–SO3−), provides ion‐exchange pathways that homoginized the Zn2+ flux, and via F‐rich chemistry forms in situ ZnF2 that suppresses parasitics and stabilizes the interface; its integrity relieves interfacial stress.
