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…
WhY shape matters: Hydrodynamics of a Y-shaped membraneless electrolyzer
Karl Schoppmann, Hannes Rox, Erik Frense +4
A novel Y-shaped membraneless flow-through electrolyzer is introduced to achieve a homogeneous electrochemical reaction across the entire electrode in a cost-efficient cell design…
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…
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…
Wettability-dependent dissolution dynamics of oxygen bubbles on Ti64 substrates
Hongfei Dai, Xuegeng Yang, Karin Schwarzenberger +2
In this study, the dissolution of a single oxygen bubble on a solid surface, here Titianium alloy Ti64, in ultrapure water with different oxygen undersaturation levels is investiga…
