Samarium strontium cobaltite

De Jonghe s group studied the effects of nanoparticle infiltration on LSM cathodes to improve the catalytic activity of LSM at reduced temperatures [75]. Smo.eSro.rCoOs-j [samarium strontium cobaltite (SSC)] was chosen to infiltrate into LSM because it is an effective electrocatalyst for oxygen reduction reactions owing to its MIEC properties. The SSC solution was prepared using the nitrate salts... 

Strontium-doped samarium cobaltite (SSC) is selected as the air electrode material of our standard cells. The slurry of Smo.sSro.sCoOs g powder is screen printed onto the electrolyte disk with an already sintered anode. The final sintering of the cathode is performed in air at a temperature range of 1000°-1200°C for 3 h. The average thickness of the porous cathode is about 30-50 pm. Figure 9.3(b) shows the electron microscope image of the air-fired microstructure of the air electrode of our standard cell. It has been demonstrated that the cathodic overpotential of the cell is very small [16].
