Intermediate-temperature nickel-yttria stabilized zirconia supported tubular solid oxide fuel cells using gadolinia-doped ceria electrolyte

► Highly sinterable GDC powders were prepared by carbonate coprecipitation. ► A Ni-YSZ-supported tubular SOFC cell with Ni, Ni-GDC, GDC, and LSCF-GDC/LSCF layers was fabricated. ► The prepared cell showed a maximum power density of 594 mW cm−2 at 600 °C. ► This study demonstrates the potential for fabrication of a tubular SOFC at a lower sintering temperature.
