The origin of strong electrolyte flow during water electrolysis is investigated, that arises at the interface between electrolyte and hydrogen bubbles evolving at microelectrodes. This Marangoni convection was unveiled only recently (Yang et al., PCC

Electrolytic gas evolution is a fundamental phenomenon occurring in a large number of industrial applications. In these processes gas bubbles are formed at the electrode from a supersaturated solution. Since dissolved gases can change the surface ten

Bei der Wasserstoffelektrolyse kann es aufgrund von Gradienten in der Konzentration und der Temperatur zu Gradienten in der Oberflächenspannung an der Phasengrenzfläche der Wasserstoffblase kommen. Die dadurch angetriebene Marangoniströmung konnte

Hydrogen produced from wind or solar power could be used easily for storing energy also at large scale, thus allowing to bridge the gap between supply and demand of renewable energy with respect to time and place. When splitting water by electrolysis

The Lorentz-force driven flow around an insulating sphere in a parallel electric and magnetic field was investigated experimentally and numerically. From the results, the lift force acting on the bubble due to the pressure reduction caused by the Lor

Hydrogen production via water electrolysis is an established method for energy storage the efficiency of which is limited by the gas bubbles blocking the electrode surface during the process. The application of a magnetic field can be a promising sol

The flow around an evolving hydrogen bubble on a microelectrode (0.1 mm in diameter) under the influence of an electrode-normal magnetic field was investigated to clarify the effect of the imposed flow on the detachment of the bubble from the electro

In water electrolysis the efficiency is related to the free area of the electrodes. Therefore a fast transport of the hydrogen bubbles away from the electrodes into the bulk is beneficial. To characterize the flow close to the cathodes surface simult
