Topic: Recent progress in understanding the evolution of gas bubbles during water electrolysis

Introduction
Electrochemical gas evolution at electrodes is a multiphysics process that involves a variety of phenomena at different scales, e.g. nucleation and wetting, capillary effects, bubble coalescence, electrolyte constitution and crossflow, supersaturation, temperature and electric fields. Today, our understanding still seems to be limited, e.g. with respect of accurately predicting the bubble departure size.  As the details of growth and transport of gas bubbles have a strong impact on the performance of electrolyzer devices, a better understanding is needed for improving their efficiency. The contribution will elaborate on recent progress in understanding how capillary, thermal, electric and wetting effects influence the gas bubble evolution, thereby combining experimental and numerical efforts.
