摘要：
NiO-Al2O3 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 Al2O3 revealed spherical particles of 30 nm and platelets of 70 nm, respectively. The XRD analysis of NiO-Al2O3 composite sintered at 900 degrees C showed presence of cubic NiO and rhombohedral alpha-Al2O3 which were chemically stable. However, above 1200 degrees C NiAl2O4 started to appear. The conductivity of NiO-Al2O3 was the highest in hydrogen (4.3 x 10(-3) S/cm at 600 degrees C). In biogas, the conductivity was 3.2 x 10(-3) S/cm with the activation energy of 0.67 eV. The stability of the composite in biogas was also examined.
