The Ni-based anodes with different electrolyte (YSZ and ScCeSZ) were modified by 1 wt% Sn, Ag, and Cu. Dopant precursors were added to porous anode via infiltration technique. Prepared cells were tested under simulated biogas with fuel composition of CH4:CO2:N2=2:1:1 at 750 °C. Cell operational stability was significantly improved with the presence of Sn or Ag in the anode. More importantly, Sn-doped cell exhibited comparable maximum power density in biogas as with hydrogen. Carbon deposition on Sn and Ag-doped anode surface was successfully prevented, hence, using Sn and Ag is a promising approach to improve Ni-based anode cells under dry methane reforming conditions.
