An improved hydrophobic coating for the porous gas diffusion layer in a PEM-based electrochemical hydrogen pump to mitigate anode flooding

Electrochemistry Communications, 2020
Anode flooding is a critical issue in proton exchange membrane (PEM)-based electrochemical hydrogen pumps. Water-proofing the gas diffusion layer (GDL) on the anode side is a highly effective approach to mitigate the flooding problem and to enhance ...

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 ...

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.

Understanding the impact of the gas diffusion layer structure on catalyst utilization in the PEM water electrolyzer

Next Energy
A multiphysics half-cell model of a polymer electrolyte membrane water electrolyzer (PEMWE) was developed to probe impacts of the detailed 3-dimensional pore structure of the gas diffusion layer (GDL) on performance characteristics. We show that pores in
