Thermal barrier coatings are an integral part of both stationary and aircraft gas turbines, since they are the only coatings that can withstand the high fuel gas temperature needed for efficient operations. The standard that has been established worldwide for thermal barrier coatings is yttria-stablized zirconia (YSZ) that has been partially stabilized with 7-8 weight % Y2O3.
IEK-1 develops ceramic membranes for separating the greenhouse gas CO2, which is to be subsequently stored in order to prevent harmful emissions.This new technology is called "carbon capture and storage" or CSS technology.
The department is developing materials and manufacturing technologies for solid oxide cells. The manufacturing focuses on the use of powder technological techniques. Main expertise is the combination of appropriate materials and functionality-adapted microstructures of multi-layer components.
Christian Doppler Laboratory
for Metal-supported Electrochemical Energy Converters
Metal-supported fuel cells (MSCs) are highly attractive regarding their mechanical robustness and cost effective processing. Within the framework of the CD laboratory, goal oriented improvement of electrodes and MSC specific interfaces are the key for further optimization of power density and long-term stability.
