A new type of bilayered-anode for application in biogas-fueled solid oxide fuel cells (SOFCs) was investigated. The bilayered-anode consisted of lanthanum-and cobaltdoped nickel oxide mixed with Sc 2 O 3 -stabilized ZrO 2 electrolyte material (LaCoNi-ScSZ) as a functional catalyst layer mainly for the reforming reaction and NiO-ScSZ as an active anode layer mainly for the electrochemical reaction. The cell performance was characterized by recording I-V curves and impedance spectra. The SOFC featuring the LaCoNi-ScSZ functional catalyst anode layer exhibited a power density of 0.32 W/cm 2 when operated under a humidified synthetic biogas (60 % CH 4 and 40 % CO 2 ) at 700°C. The presence of LaCoNi-ScSZ functional catalyst afforded a high coking resistance, and thus the cell was stable when operated under the synthetic biogas at 700°C for 45 h.
