Thin Reinforced Sulfonated Poly(phenylene sulfone) Membranes for Durable Water Electrolysis: Suppressed Swelling and Enhanced Stability Over 2000 Hours

Advanced Energy Materials, EarlyView.
Hydrocarbon membranes have the potential to significantly enhance the efficiency of water electrolyzers. However, their application is often limited by insufficient stability resulting from excessive swelling. This work presents a strategy to achieve efficient, safe and stable operation of a 24 µm thin hydrocarbon membrane by combining a modified ...

CO Spillover‐Induced Directed C─C Coupling for CO2 Electroreduction to Multicarbon Products

Advanced Energy Materials, EarlyView.
Efficient CO2 electroreduction to C2+ is achieved by engineering Cu@Ag interfaces, which enhance interfacial CO spillover from Ag to Cu, enrich *CO coverage, and accelerate C─C coupling. A quantitative relationship between CO spillover rate and C2+ activity is also established, defining spillover as a measurable descriptor and advancing rational ...

Catalyst Layer Modifications for Enhanced Performance of Fluorine‐Free Proton Exchange Membrane Fuel Cells

Advanced Energy and Sustainability Research, EarlyView.
Considerable improvement in the performance of fully‐hydrocarbon‐based fuel cells is necessary to replace and compete with Per‐ and polyfluoroalkyl substances‐containing fuel cells. Herein, a way to enhance the ionic conductivity of the catalyst layer (CL) by incorporating insoluble ionomer particles into the CL is presented.
