Abstract:	NiO-Al O nanocomposite has been synthesized by mixing combustion synthesized powders. The nanocomposite is an effective anode/anode functional layer for intermediate temperature solid oxide fuel cells. The TEM of NiO and Al O revealed spherical particles of 30 nm and platelets of 70 nm, respectively. The XRD analysis of NiO-Al O composite sintered at 900 °C showed presence of cubic NiO and rhombohedral α-Al O which were chemically stable. However, above 1200 °C NiAl O started to appear. The conductivity of NiO-Al O was the highest in hydrogen (4. 3 × 10 S/cm at 600 °C). In biogas, the conductivity was 3. 2 × 10 S/cm with the activation energy of 0. 67 eV. The stability of the composite in biogas was also examined.
