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.
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
- characterization in half and full cell tests
- nanostructural analysis methods via operando electron microscopy
- electro-structural and kinetic electrochemical simulations
