Abstract

A bilayered yttria-doped bismuth (YDB) and gadolinia-doped ceria (GDC) composite electrolyte has been developed using painting/screen printing method. SOFC fabricated from the composite electrolyte showed 70-100 mV increase in open-circuit potential at 500°C, depending on the thickness ratio of YDB layer to GDC substrate, as compared to that from a single GDC layer. Moreover, under fuel cell operation condition, YDB/GDC composite electrolyte demonstrated higher specific conductivity than single GDC layer electrolyte at 600°C. These results showed the YDB/GDC composite electrolyte as a promising candidate for electrolyte for low temperature solid oxide fuel cells.
