Nano-sized LSM-YSZ composite was co-synthesized by a glycine-nitrate process (GNP). Transmission electron microscopy revealed that the as-prepared LSM-YSZ particles consist of nano-sized powders with a dominant YSZ phase. Backscatter electron image shows that LSM and YSZ phases were regularly dispersed within the composite. Alternating current impedance measurement revealed that the co-synthesized LSM-YSZ electrode shows lower polarization resistance and activation energy than the physically mixed LSM-YSZ electrode. This electrochemical improvement would be attributed to the increase in three-phase boundary and good dispersion of LSM and YSZ phases within the composite.
