Fuel Cells for High Temperature Applications (SOFC)

ISTEC activities mainly deal with the study and optimization of those ceramic processes cheap and easily scalable able to produce the abovementioned ceramic devices in an easy and environmental friendly way. ISTEC exploits the most common techniques used in the traditional ceramic industry:

tape casting,

die pressing,

screen printing,

powder wet spray,

to optimize the production of the three generations of planar SOFC:

electrolyte-supported cells,

electrode-supported cells,

metal-supported cells.

The conventional yttria stabilized zirconia (YSZ) as well as the most innovative gadolinia doped doped ceria (GDC) and more recently proton conductors based on barium cerate-zirconate (BCY, BCZY) are used as electrolytic materials. The main objective of the research is to individuate the relation that links powders properties with microstructure and electrochemical performances of the final object, key issue to optimize the whole process for the SOFC production. For this purpose ISTEC is devoted to the SOFC production optimizing the whole ceramic process, starting from the powders synthesis to their forming and sintering as well as their chemic-physical and microstructural characterization.
