Electrochemistry enables us to decarbonize and transform entire sectors by using renewable electricity to create sustainable fuels, chemicals, and materials. At the heart of this transformation sits green hydrogen produced by water electrolyzers, yet their cost, performance, and long-term stability have still prevented their successful market implementation. Stability depends on the catalyst layer dissolution behavior, which has been investigated in both fundamental Aqueous Model Systems (AMS) and more applied Membrane Electrode Assemblies (MEA). However, the discrepancy in results between these two suggests the need for further research to close the gap between fundamental and applied electrocatalysis.

My research involves dissolution studies on oxygen evolution reaction (OER) catalysts using Gas Diffusion Electrode (GDE) and Membrane Electrode Assembly (MEA) Setups coupled to an Inductively Coupled Plasma Mass Spectrometer (ICP-MS) for online downstream electrolyte analysis. Using High-Throughput Experimentation (HTE) methods and Machine Learning (ML) algorithms will allow me to accelerate workflows and efficiently screen the vast (electro-)chemical parameter space under realistic conditions.
