Catalytic properties and coking stability of composite materials based on NiO and doped apatite-type lanthanum silicates were studied for their using as anode materials for internal methane reforming in intermediate temperature solid oxide fuel cells. Samples based on Sr- or Al-doped lanthanum silicate were prepared by modified Pechini methods. The composite materials were characterized by X-ray diffraction, methane steam reforming and temperature programmed oxidation. The effects of La(0.8)Sr(0.2)Mn(0.8)Cr(0.2)O(3) addition, partial Ni substitution with La(0.1)Sr(0.9)TiO(3) ionic and electronic mixed conductor and composition of apatite-type lanthanum silicate on catalytic properties and coking resistance were considered.
