A Theoretical Model for the Triple Phase Boundary of Solid Oxide Fuel Cell Electrospun Electrodes [PDF]

Applied Sciences, 2019
Electrospinning is a new state-of-the-art technology for the preparation of electrodes for solid oxide fuel cells (SOFC). Electrodes fabricated by this method have been proven to have an experimentally superior performance compared with traditional ...

Identification of the active triple-phase boundary of a non-Pt catalyst layer in fuel cells. [PDF]

Sci Adv, 2022
The rational design of non-Pt oxygen reduction reaction (ORR) catalysts and catalyst layers in fuel cells is largely impeded by insufficient knowledge of triple-phase boundaries (TPBs) in the micropore and mesopore ranges. Here, we developed a size-sensitive molecular probe method to resolve the TPB of Fe/N/C catalyst layers in these size ranges.

Electrochemically driven C-N bond formation from CO₂ and ammonia at the triple-phase boundary. [PDF]

Chem Sci, 2022
Electrocatalytic formation of C–N bonds was achieved through the electrolysis of CO 2 and NH 3 over Cu catalysts. A combined analytical and spectroscopic approach gave insights into the reaction mechanism leading to formamide and acetamide products.

Understanding the Role of Triple Phase Boundaries on Coating-Free Solid-State Cathodes. [PDF]

ACS Energy Lett
Sulfide solid electrolytes have high ionic conductivities necessary to achieve high-rate solid-state cathodes at room temperature and low pressure. Cathode active materials generally require coatings to avoid deleterious oxidative decomposition reactions with the electrolyte. Coatings add cost and complexity to the manufacture.

Modelling the triple phase boundary length in infiltrated SOFC electrodes

International Journal of Hydrogen Energy, 2017
Abstract A model based on the principles of coordination number and percolation theory is proposed for calculating the triple phase boundary (TPB) lengths in the Solid Oxide Fuel Cell (SOFC) electrodes infiltrated with nano particles. The TPB length is a critical microstructural property that influences the cell performance. Empirical expressions for

Triple-phase contrast-enhanced computed tomography findings in dogs with cholangiocarcinoma and combined hepatocellular-cholangiocarcinoma: Pilot study [PDF]

Open Veterinary Journal
Background: Recently, the usefulness of triple-phase contrast-enhanced computed tomography (CT) scans for liver tumors in canines has been reported. However, detailed information on the CT findings of cholangiocarcinoma (CCA) and combined hepatocellular-

Bernoulli’s principle-mediated Cl2 electrosynthesis [PDF]

Nature Communications
Existing technologies for chlorine (Cl2) synthesis are generally suffered from low productivity or high production cost. Guided by Bernoulli’s principle, here we report an efficient yet cost-effective electrochemical system for Cl2 electrosynthesis ...

New phase-field model for polycrystalline systems with anisotropic grain boundary properties

Materials & Design, 2022
In this paper, a new methodology is presented to inlude anisotropic grain boundary properties in a phase-field model. The new approach is thermodynamically consistent and gives accurate control of the inclination and misorientation of grain boundary ...
