Sulfonated Diels–Alder Poly(Phenylene)s in Membrane Electrode Assemblies for Fuel Cells

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
This study reveals that ionomer adsorption is the key performance‐limiting factor for sulfonated Diels–Alder poly(phenylene)s in fuel cell cathodes, with interfacial incompatibility and hydrophilicity also contributing. High performance is retained in membranes and anodes, but significant losses occur when used as cathode binders.

In Situ SERS Study of Electrocatalytic CO2RR on Au@Pd Bimetallic Catalysts: From Isolated Single Atoms to Monolayer of Pd

open access: yesAggregate, EarlyView.
Through in situ SERS probing of the electrocatalytic CO2RR on Au@Pd catalysts with varying Pd coverage, isolated Pd single atoms on Au are found to exhibit optimal CO activity via balanced *COOH/*CO adsorption energies. At Pd step edges, surface *H is revealed to reverse the *CO adsorption configuration—providing insights for guiding fine‐tuning of the
