Fuel flexibility: A key challenge for SOFC technology

► Ni was mainly present as highly dispersed La2NiO4 particles on the perovskite. ► The advantage of this new anode consists in the direct utilization of dry fuels. ► A reasonable steady-state performance was reached under all reaction conditions. ► No carbon and good performance were detected for the SOFC anode. ► Mixed conductivity of the CGO electrolyte affected the electrical efficiency.
