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 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

H2Giga - StacIE | Stack Scale-Up: Industrialization PEM Electrolysis

The project StacIE aims to scale up the stack production on the level of cell components by development of industrial processes, improvement of profitability of cell design by reducing complexity and optimizing manufacturing technique of the porous transport layer (PTL) and bipolar plate (BPP). For PTL and BPP alternative materials and substrate coating methods are identified and developed further.
