- An in situ reduction method has been used to synthesize NiO-Sm0.2Ce0.8O1.9 (NiO-SDC) nanocomposites for SOFC anodes. The effect of NiO content on the crystalline phase, crystallite size, and average particle size is investigated. The anode-supported solid oxide fuel cells have been fabricated from the NiO-SDC nano-composite powders with NiO contents ranging from 40 to 60 wt%. Uniform pore structure of the anode is exhibited after testing although without adding pore former. The electrochemical performance of the anode-supported cells has been tested at 600-700°C using humidified hydrogen as fuel. The cell with 60 wt% NiO has an open circuit voltage (OCV) of 0.69 V with a maximum power density of 506 mW/cm2 at 700°C.While at lower temperature (600°C), the cell with 50 wt% NiO has the maximum power density of 326 mW/cm2.
