Unveiling Bubble Dynamics of Proton Exchange Membrane Water Electrolysis at Elevated Temperatures

EcoEnergy, EarlyView.
This work directly visualizes bubble dynamics in a proton‐exchange membrane water electrolyzer operated at temperatures up to 120°C and pressures up to 100 bar. Elevated‐temperature operation beyond the atmospheric boiling point markedly reduces bubble coverage, leading to lower bubble‐related voltage losses and enhancing cell performance.

Breaking the Activity–Stability Scaling in RuO2 via Single‐ and Dual‐Doping Strategies

EcoEnergy, EarlyView.
Single and dual heteroatom doping redefines RuO2 for acidic oxygen evolution by synergistically tuning the electronic structure, lattice stability, and reaction pathways. Although single dopants optimize specific catalytic properties, dual dopants overcome the activity–stability trade‐off through cooperative electronic and geometric regulation ...

Unveiling Anodic Reconstruction of Electroless‐Deposited Dual‐Sided NiFeP Catalyst‐Coated Membranes for Efficient Anion Exchange Membrane Water Electrolysis

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A rapid electroless deposition strategy enables the 15 min fabrication of dual‐sided NiFeP catalyst‐coated membranes (CCMs) for anion exchange membrane (AEM) water electrolysis. The resulting ionomer‐free CCMs offer strong membrane‐catalyst adhesion and efficient ionic transport.

Developing a Suitable Anion Exchange Layer Structure for Pure–Water Fed Bipolar Membrane CO2 Electrolysis

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A porous anion exchange layer (AEL) is implemented in a forward‐biased bipolar membrane CO2 electrolyzer to suppress carbonate crossover, support CO2 regeneration and maintain cathode alkalinity. Two fabrication strategies are compared—deposition on a silver gas diffusion electrode (GDE) or on the CEM—showing that a porous AEL‐coated GDE provides the ...

Advances in Design Strategy and Mechanism Insights for Alkaline Hydrogen Evolution Reaction: Multilevel Site Engineering and Structure–Activity Relationship

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This review is about material design based on engineering multilevel sites from theoretical calculation and synthetic routes to mechanism, structure–activity relationship, challenges and perspectives for boosting hydrogen production in alkaline electrolyte. Electrolytic water splitting is a clean, carbon‐free method for producing green hydrogen and has

Revealing Structure–Performance Relations in Core‐Shell Catalyst‐Based PEM Water Electrolyzer Anodes with Low Iridium Loading

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Table of Contents The TiO2@IrO2 core–shell architecture ensures high electronic conductivity even at a low iridium content of 10 wt%. The resulting catalyst layer shows significantly higher iridium utilization than a commercial reference, leading to improved PEMWE single‐cell performance at low iridium loading.
