Project work

The transport properties of materials and functional/protective coatings and their change with operating time (degradation) are identified in air/simulated flue gas at appropriate process temperatures. Characterization is performed by means of electrochemical impedance spectroscopy and conductivity relaxation measurements in the frequency domain. The modelling of the transport processes in multilayer membranes aims to design new multilayer membrane concepts on the computer and optimize them with respect to efficiency and stability.
