Cathodes Produced by Infiltration

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 

LSCF is another promising cathode material for intermediate-temperature SOFCs [81, 82]. Owing to its much higher oxygen ionic conductivity than LSM, 

A different approach was taken by Nie et al. to produce an LSCF cathode using infiltration [85]. The porous LSCF was produced by tape casting. Both sides of YSZ were covered with SDC slurry to prevent the reaction between LSCF and YSZ, and as a result symmetrical LSCF-SDC-YSZ-SDC-LSCF cells were produced. Nitrate solutions of SDC were prepared using Sm(N03)2-6H20 and Ce(N03)3 -6H20 in water. The solution was infiltrated into both sides of the LSCF. 

Despite the advantages of the methods mentioned above, it also introduces some complexities into the production process. In order to achieve the necessary
