Masterthesis "Development of a measurement cell for Raman microscopy on ionomer membranes"
Mechanical Engineering, Electrical Engineering, Chemical Engineering, Physics, or similar disciplines
Ionomer membranes are crucial components of many electrochemical devices, like proton exchange membrane (PEM) fuel cells and PEM waterelectrolyzers, which are vital for the energy transition. The membranes act as separators between the electrodes and have to provide high ion conductivity while maintaining their structural integrity during long term operation at harsh electrochemical and physical conditions. Current polymer systems have to be optimized in order to achieve these properties. Reliable characterization of the membranes is essential for a targeted optimization towards specific applications. With confocal Raman microscopy, chemical analyses of polymers can be conducted at a high spatial resolution, yet the method is typically applied off the normal operating conditions of the membranes. Within the project, a measurement cell as an add-on to a confocal Raman microscope will be manufactured that allows to perform this characterization under in situ conditions. Subsequently, first experiments with state of the art ionomer membranes will be performed and evaluated.
You are interested in the development and implementation of new methods to characterize energy materials. You have profound knowledge in the area of CAD and manufacturing. You are motivated, team-minded, communicative, and are able to work independently. In an ideal case you are experienced in one or more of the following topics: Raman spectroscopy, optics, polymer chemistry, electrochemistry.
outstanding working conditions in a young and interdisciplinary team. In an open environment you will have the freedom to develop and realize your own ideas. You can find further information on the Helmholtz-Institute Erlangen-Nürnberg for Renewable Energy and on the Electrocatalytic Interface Engineering Research Department at www.hi-ern.de.
