Electrochemical energy and process engineering

The laboratory offers the most important electrochemical energy storage systems. For research and training purposes, test stands are operated mostly in the small power range. From lithium-ion batteries to fuel cells, all promising electrochemical energy converters and energy storage systems are available. Modern source-sink systems in the power range up to 1 kW are available for characterizing the energy systems and for material tests, for example for investigating different fuel cell membranes. The prerequisites are also in place for sophisticated characterization methods such as electrochemical impedance spectroscopy. In order to closely integrate experiments and modeling, a simulation workstation with Comsol Multiphysics is available specifically for batteries and fuel cells.

The laboratory is constantly being further developed within the framework of regular projects and final theses.

Further experiments from the field of renewable energies and process engineering are available for teaching purposes within the framework of practical courses.
