Porous ceramic
Porous NiO-Ce0.8Sm0.2O1.9(NiO-SDC)ceramics with homogeneous pore distribution were prepared using polystyrene(PS)spheres as pore templates.NiO-SDC powders were synthesized by a glycine-nitrate method, ultrasonically mixed with PS spheres in ethanol,dried and then pressed into green pellets.The pellets were sintered to yield porous NiO-SDC ceramics.The effects of the sintering temperature on the microstructure and mechanical strength of the ceramics were investigated.NiO-SDC ceramics sintered at 1200 and 1350℃ have interconnected pore structures and high compression strength.When single cells were fabricated using porous NiO-SDC ceramics as anode-supported layers,the peak power density of the cells at 600℃ was 333 and 353 mw.cm-2 for ceramics sintered at 1200 and 1350℃,respectively.The results indicated that these porous ceramic materials are promising for anode substrates for solid oxide fuel cells.
