Characterization and Electrochemical Performance of Ce sub>1-XFexO 2-δ Anode for Solid Oxide Fuel Cell Running on Methane Fuel
Subscript textAn anode material of Ce sub>1-xFexO sub>2-δ (x=0.1, 0.2) for the oxidation of dry methane has been investigated. Ce sub>1-xFexO2-δ is synthesized by the citrate method. The electrochemical behavior of anode is analyzed by electrochemical iSubscript textmpedance spectroscopy. Ce1-xFexO 2-δ (x=0.1, 0.2) has shown the properties of electrochemical oxidation of methane at these temperatures (550~700°C) and the polarization resistance decreases with increasing Fe content. The Ce0.9Fe0.1O2-δ showed little degradation in long-term operation while the Ce0.8Fe 0.2 O sub>2-δ showed degradation.
