Impact of Transition Metals and Electrocatalyst Layer Thickness on the Pt‐Based Cathodes of Proton Exchange Membrane Fuel Cells – Do Multimetallic Electrocatalysts Necessarily Yield an Improved Performance?

open access: yesAdvanced Energy Materials, EarlyView.
Nonnoble transition‐metals (TMs) in PtCuNi/C catalysts have a dual influence in proton‐exchange membrane fuel cell cathode catalyst layer. While TMs act as a “sacrificial component” of PtCuNi/C, inhibiting Pt dissolution from the PtMx nanoparticles bearing the active sites, they promote the formation of separate catalysts and ionomer domains in the ...

Understanding the Metal‐Center Mediated Adsorption and Redox Mechanisms in a FeMn(NbTa)2O6 Columbite Material for Anion Exchange Membrane Water Electrolyzers

open access: yesAdvanced Energy Materials, EarlyView.
FeMn(NbTa)2O6‐columbite is a sustainable and high‐performance bifunctional electrocatalyst for anion exchange membrane water electrolyzers, comparable to benchmark catalysts. In situ XAS and DFT analysis show Fe/Mn sites exhibit higher OER activity due to reduced overpotentials and favorable O→OOH energetics. The Nb/Ta sites facilitate charge transfer,

Transport Resistance Dominates the Fill Factor Losses in Record Organic Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
Organic photovoltaics are a promising solar cell technology, but even the record devices with 20% efficiency have significant fill factor losses due to low active layer conductivities. In this Perspective, the authors describe the origin of these losses, discuss experimental methods for their quantification, and explain how to minimize them to optimize
