Materials and processes for solid oxide fuels cells (SOFC) or solid oxide electrolyte cells (SOEC)
Principal investigator: Vincenzo M. Sglavo
Several reseach activities have been carried out in the last decade to improve efficiency, durability and flexibility of Solid Oxide Fuel Cells (SOFC). Recently, planar CuO-containing GDC anode and Li-doped GDC-based electrolyte were produced by tape casting and co-sintering to obtain SOFC which can be fed by carbon and/or sulphur containing fuels like biogas. Larger anode/electrolyte thickness ratio was shown to have a positive influence on SOFC performance because of the better electrolyte densification promoted by compressive stresses generated upon sintering because of the differential anode/electrolyte shrinkage. The catalytic activity analysis pointed out that GDC promotes complete methane combustion and Cu is unable to activate the C-H bond of methane, this being advantageous for limiting the presence of carbon deposits. The cell with better microstructure (i.e., with denser electrolyte) was tested by using wet CH4/CO2 biogas mixture at 650°C and power density of 29 mW cm-2 was measured.
