Characterization of MOy–MxCe1−xO2−δ (M: Co, Ni & Cu) nano powders and anode materials for low and intermediate temperature solid oxide fuel cells

摘要: Abstract The development of new anode materials is necessary for low and intermediate temperature solid oxide fuel cells (SOFCs) to improve cell lifetime performance decrease operating temperature. In this study, nanocrystalline powder with the novel composition: MO y –M x Ce 1−x O 2−δ (M = Ni, Co Cu) were synthesized by glycine nitrate process (GNP). crystal structure, morphology, specific surface area (SSA), particle size distribution powders, investigated using various techniques (e.g., BET, SEM, XRD, TEM). results demonstrated significant improvement on characteristics optimize property materials. nano powders consisted two main phases fluorite rock salt structure. scale ranged from 5 600 nm a high SSA 14.95–20.50 m 2  g −1 , which are quite important such as porosity, density contact area. Electrolyte supported single having LSM/GDC/ceria-based produced aforementioned exhibited 0.35 W cm −2 at 700 °C under 25 ml/min pure dry methane (CH 4 ) feeding. Dry hydrogen (99.9%) was used starting gas reduce layer side 30 min.
