Electrocatalytic water splitting is currently one of the most promising reactions to produce "green" hydrogen and consequently, proton exchange membrane water electrolysis (PEMWE) is of particular interest. The central research question is how to improve the performance and reduce degradation. Particularly, the water splitting reactions at the anode, namely, oxygen evolution reactions (OER) is the largest obstacle. Highly active and stable catalysts such as Iridium oxide are used to reach high conversion rates. For the development of these catalysts, it is curical to understand the electrochemical processes they undergo and their changes during the operation.

In this scientific context, my research includes dynamic modeling and simulation of oxygen evolution reactions (OER) on anode electrodes at micro- and macrokinetic scale. The model enables the analysis, and the optimization of the full-cell systems.
