Abstract

The SrCo_0.9Sb_0.1O_3-δ (SCS) composite oxide with cubic perovskite structure was synthesized by a modified Pechini method, and examined as a novel cathode for intermediate-to-low temperature solid oxide fuel cells (ILT-SOFCs). At 700°C and under open-circuit condition, a symmetrical SCS cathode on Sm_0.2Ce_0.8O_1.9 (SDC) electrolyte showed a low polarization resistance (R_p) of 0.09 Ωcm² in air. A porous layer of SCS was deposited on an anode-supported fuel cell, consisting of a ∼30 μm thick dense electrolyte of SDC prepared by a cost-effective dip coating process, and an NiO-SDC cermet as an anode (Ni-SDC/SDC/SCS). The single cells obtained were tested with humidified (∼3% H₂O) hydrogen as fuel and static air as oxidant. A high open-circuit voltage of 0.86 V, a maximum power density of 354 mW/cm², and a low polarization resistance of the electrodes of 0.13 Ωcm² was achieved at 650°C.
