| Abstract: | The performance of Ce1−xFexO2−δ (x = 0.1, 0.2) was studied as anode for solid oxide fuel cell running on methane in this paper. The oxides were prepared by the citrate method. The polarization resistance of electrode was measured in the two-electrode symmetric cell configuration and an electrolyte-supported cell was prepared to assess Ce0.8Fe0.2O2−δ anode performance of running on methane fuel. The results suggested that Ce0.8Fe0.2O2−δ has a significant effect on the electrochemical oxidation of methane. A maximum power density of single cell was 52 mW/cm2 at 800 °C and little carbon deposition was shown on the anode operating in humidified methane for 20 h. Therefore, Ce0.8Fe0.2O2−δ is a promising candidate for anode of solid oxide fuel cell running on methane fuel, which breaks a new path to solve the problem of carbon deposition in methane. |
