Nanoanalysis of Electrochemical Processes

About

Understanding the mechanisms that alter nanostructures during electrochemical processes is crucial to develop electrolyzer and fuel cell technology. With this knowledge it is possible to enhance efficiency, resilience, and durability of the devices. Scaling those up allows to efficiently use hydrogen technology to store renewable energy.

To do so, we employ scale-bridging, correlative analysis methods covering full-stack analysis, in situ degradation studies, modeling, and operando liquid phase electron microscopy.

Research Topics

To investigate the processes related to formation and alteration of the nanostructures involved, we combine a toolbox of methods that include

synthesis of new catalytic materials
development of accelerated stress test protocols
nanostructural analysis methods via operando electron microscopy
electro-structural and kinetic electrochemical simulations
electron beam-induced effects in liquid phase electron microscopy
quantitative liquid phase electron microscopy
