Decoupling Membrane Electrode Assembly Materials Complexity from Fuel Cell Performance through Image‐Based Multiphase and Multiphysics Modelling

open access: yesAdvanced Energy Materials, EarlyView.
A high‐resolution image‐based multiphase and multi‐physics modelling framework is developed to decouple structural changes in the membrane electrode assemblies of high‐temperature proton exchange membrane fuel cells. These changes are then digitally combined to show how morphological defects such as membrane pores, catalyst cracks, and phase migration ...

Efficient Forward‐Bias Bipolar Membrane CO2 Electrolysis in Absence of Metal Cations

open access: yesAdvanced Energy Materials, EarlyView.
Alkali‐metal cations are assumed to be indispensable for CO2 reduction, but often lead to undesired failure mechanism such as salt precipitation due to the non‐electrochemical CO2 conversion to (bi)carbonates. A promising alternative CO2 reduction cell design involves the use of pure water and a metal cation‐free forward‐bias bipolar membrane ...

Floatable Protective Layers: a Strategy to Minimize Solid Electrolyte Interphase Growth and Maximize the Lithium Utilization

open access: yesAdvanced Energy Materials, EarlyView.
The floatable protective layer is synthesized via surfactant‐assisted solvent drying of a porous conductive layer. It promotes preferential deposition of lithium beneath the layer, while enabling solid electrolyte interphase formation above it. This design minimizes direct electrolyte contact with freshly deposited lithium, reducing side reactions and ...
