Bubble growth on arrays of micro-electrodes
Mengyuan Huang, Gerd Mutschke, Zhicheng Yuan +1
Gas bubbles evolving on electrodes during water-electrolysis are blocking active reaction area, thus hindering mass transfer and raising Ohmic resistance. Unlike earlier models tha…
Wetting effects on the dynamics of droplets and bubbles at surfaces
Yifan Han, Kerstin Eckert, Gerd Mutschke
Dynamic wetting plays a fundamental role in the dynamics of droplets and bubbles at solid surfaces by influencing contact line motion and interfacial evolution. In this work, three…
A geometric interpolation scheme for applying dynamic wetting to three-dimensional volume of fluid simulations
Yifan Han, Gerd Mutschke, Kerstin Eckert
This paper presents a three-dimensional framework for simulating dynamic wetting phenomena using the volume of fluid (VOF) method, implemented in Basilisk. A geometric interpolatio…
Dynamic equilibrium of electrochemical bubbles growing on micro-electrodes
Mengyuan Huang, Chao Sun, Kerstin Eckert +2
In gas evolving electrolysis, bubbles grow at electrodes due to a diffusive influx from oversaturation generated locally in the electrolyte by the electrode reaction. When consider…
Boosting electrode performance and bubble management via Direct Laser Interference Patterning
Hannes Rox, Fabian Ränke, Jonathan Mädler +9
Laser-structuring techniques like Direct Laser Interference Patterning show great potential for optimizing electrodes for water electrolysis. Therefore, a systematic experimental s…
Electrolyte spraying within H bubbles during water electrolysis
Aleksandr Bashkatov, Florian Bürkle, Çayan Demirkır +10
Electrolytically generated gas bubbles can significantly hamper the overall electrolysis efficiency. Therefore it is crucial to understand their dynamics in order to optimise water…
Bubble size distribution and electrode coverage at porous nickel electrodes in a novel 3-electrode flow-through cell
Hannes Rox, Aleksandr Bashkatov, Xuegeng Yang +4
A novel 3-electrode cell type is introduced to run parametrical studies of H evolution in an alkaline electrolyte on porous electrodes. Electrochemical methods combined with a…
H bubble motion reversals during water electrolysis
Aleksandr Bashkatov, Alexander Babich, Syed Sahil Hossain +3
The dynamics of hydrogen bubbles produced by water electrolysis in an acidic electrolyte are studied using electrochemical and optical methods. A defined cyclic modulation of the e…
