Abstract

Cost and reliability of solid oxide fuel cell (SOFC) system resulting from high operating temperature severely hinders its wide-spread commercialization. In this study, high performance low temperature SOFCs with hierarchically porous nano cathode network (Sm_0.5Sr_0.5CoO₃-Gd_0.1Ce_0.9O_2-δ, SSC-GDC) have been fabricated by vacuum-free infiltration and subsequent freeze-drying combustion. The straight open GDC cathode skeleton and NiO-GDC anode substrate prepared by freeze-drying tape-casting facilitate mass transport while the nano cathode catalyst promotes the electrochemical reactions. The cell with straight open electrodes and hierarchically porous cathode network demonstrates a maximum power density of 0.65Wcm^-2 at 500°C and impressive stability for more than 500h at 400°C using H₂ as fuel and ambient air as oxidant. The simple and cost-effective fabrication process is expected to significantly impact the SOFC operability and accelerate its commercialization.
