Compared to Ni(O) cermet, an oxide anode is much better for a solid oxide fuel cell at suppresses coking and carbon deposition with carbonaceous fuels. Furthermore, a small amount of metal nanoparticles can enhance the electrochemical performance of the oxide anode while maintaining compatibility with the carbonaceous fuel when anchored on the oxide surface. In this study, ferrate-based perovskites (La_0.95Fe_0.80Ni_0.05Ti_0.15O₃, LFNT) with Ni⁰ particles exsolution are investigated via B-site doping to increase the stability at 800 ^oC in H₂ atmosphere and electrocatalytic capability for fuel oxidation. Surprisingly, the B-site doped LaFeO₃ (La_0.95Fe_0.8Mg_0.2O₃, LFM) showed a high oxide-ion conductivity of 10 mS cm^-1 with limited electronic conduction and further doping of Ti⁴⁺ or Ni²⁺ could increase the electronic conductivity to 30 Scm^-1 and 100 Scm^-1 at 800 ^oC for the reduced La_0.95Fe_0.8Mg_0.05TiO₃ (LFMT) and LFNT, respectively. The cell with LFNT anode on a La_0.9Sr_0.1Ga_0.8Mg_0.2O_2.85 electrolyte shows a polarisation resistance of 0.32 Ωcm² at 800 ^oC and a high power density of 600 mWcm^-2 can be obtained when ceria is added via infiltration as a co-catalyst.
