Abstract
The microstructure control of NiO-YSZ for SOFC anode was performed using rice starch as pore former. Positively-charged NiO-YSZ slurry and negatively-charge rice starch slurry were heterocoaglated and then filtrated to prepare green plates. The rice starch was burnt out by sintering in air and porous NiO-YSZ electrode was obtained. The surface of NiO-YSZ substrate was coated with conductive polypyrrole to give electric conduction that is essential for EPD processing. The GDC/LSGM/GDC laminar coating was conducted by sequential deposition on the same substrate. The electrolyte layers were easily sintered together on the anode without cracking and peering-off at the interfaces.
