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
The paper uses a three‑dimensional volume‑of‑fluid simulation with a dynamic wetting model to study how wetting influences droplet splashing, bubble coalescence on solid surfaces,…
Bubble-induced versus thermodynamic voltage losses during pressurized alkaline water electrolysis
Hannes Rox, Feng Liang, Robert Baumann +6
Understanding how bubbles influence the efficiency of water electrolysis is crucial to achieve economically competitive hydrogen, generated by renewable energy sources, such as win…
Monitoring of Fluid Transport in Low Temperature Water Electrolyzers and Fuel Cells: Emerging Technologies and Future Prospects
Zehua Dou, Laura Tropf, Tobias Lappan +7
Low temperature water electrolyzers (LTWEs) and low temperature hydrogen fuel cells (LTFCs) present a promising technological strategy for the productions and usages of green hydro…
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…
Scanning Acoustic Microscopy for Quantifying Bubble Evolution in Alkaline Water Electrolyzers
Zehua Dou, Hannes Rox, Zyzi Ramos +8
Improved understanding of gas/liquid transport in electrochemical gas-evolving systems is increasingly demanded for optimizing device performance. However, high-resolution measurem…
