Operando Magnetic Resonance Imaging for Visualizing Electrochemical Triple‐Phase Boundary

Angewandte Chemie International Edition
Abstract The triple‐phase boundary (TPB) is a complex interface where gas, liquid, and solid phases converge, crucially regulating the efficiency and performance of many electrochemical devices including fuel cells and batteries.

Screening Anti-Oxidant Activity at Oil Microdroplet Triple Phase Boundary Electrodes

SAE Technical Paper Series, 2009
<div class="htmlview paragraph">Highly non-polar/non-conducting media such as natural or synthetic oils cannot be analysed by conventional single phase solution voltammetry, but it is shown here that, when they are deposited onto suitable basal plane pyrolytic graphite electrode surfaces, the triple phase boundary reaction zone in liquid | liquid

Revealing the Role of the Ionomer at the Triple-Phase Boundary in a Proton-Exchange Membrane Water Electrolyzer

The Journal of Physical Chemistry Letters
In the anodic catalyst layer of a proton-exchange membrane (PEM) water electrolyzer, the triple-phase boundary (TPB) is mainly distributed on the surface of ultrafine iridium-based catalysts encapsulated by the ionomer within the catalyst-ionomer agglomerate.

Protons crossing triple phase boundaries based on a metal catalyst, Pd or Ni, and barium zirconate

Physical Chemistry Chemical Physics, 2013
Density functional theory calculations are used to investigate the energetics of protons crossing triple phase boundaries based on a metal catalyst, Pd or Ni, and barium zirconate. Our calculations show that the proton transfer reaction at these interfaces is controlled by the terminal layer of the electrolyte in contact with the metallic and gas ...

Precise Construction of the Triple-Phase Boundary and Its Antiphosphate Poisoning Effect in the Confined Region

Inorganic Chemistry
As a critical component for the oxygen reduction reaction (ORR), platinum (Pt) catalysts exhibit promising catalytic performance in High-temperature-proton exchange membrane fuel cells (HT-PEMFCs). Despite their success, HT-PEMFCs primarily utilize phosphoric acid-doped polybenzimidazole (PA-PBI) as the proton exchange membrane, and the phosphoric acid

Understanding the Roles of Double- and Triple-Phase Boundaries in High-Temperature CO ₂ Electrolysis

Nano Letters
High-temperature solid oxide electrolysis cells are promising for CO2-to-CO conversion with high selectivity and energy efficiency. However, the correlation between the electrolysis performance and electrode interface structure remains poorly understood.
