Pr 2 NiO 4 –Ag composite was synthesized and evaluated as cathode component for low temperature solid oxide fuel cells based on ceria-carbonate composite electrolyte. X-ray diffraction analysis reveals that the formation of a single phase K 2 NiF 4 –type structure occurs at 1000 °C and Pr 2 NiO 4 –Ag composite shows chemically compatible with the composite electrolyte. Symmetrical cells impedance measurements prove that Ag displays acceptable electrocatalytic activity toward oxygen reduction reaction at the temperature range of 500–600 °C. Single cells with Ag active component electrodes present better electrochemical performances than those of Ag-free cells. An improved maximum power density of 695 mW cm −2 was achieved at 600 °C using Pr 2 NiO 4 –Ag composite cathode, with humidified hydrogen as fuel and air as the oxidant. Preliminary results suggest that Pr 2 NiO 4 –Ag composite could be adopted as an alternative cathode for low temperature solid oxide fuel cells.
