Microstructural investigation of the effect of electrospraying parameters on LSCF films

Recent progress in nanostructured electrodes for solid oxide fuel cells deposited by spray pyrolysis

“…The influence of the solvent type on the morphology of LSCF cathodes prepared by ESD was investigated by Sindiraç et al [99]. The results revealed that a mixture of 2-butoxyethanol and ethylene-glycol should be employed instead of the conventional solvents used in the literature (ethanol and buty-carbitol) with lower boiling point.…”

“…The results revealed that a mixture of 2-butoxyethanol and ethylene-glycol should be employed instead of the conventional solvents used in the literature (ethanol and buty-carbitol) with lower boiling point. The deposition temperature was optimized at 350 ºC, achieving the coral-like and the cracked films Rp values of 0.82 and 1.63 Ω cm 2 at 700 ºC, respectively [99]. By considering the low thermal stability of the nanostructured electrodes, the effects of the deposition and annealing temperature on the microstructural and electrical properties of LSCF films were investigated [100].…”

Effects of electrospraying parameters on deposition of La0.3Sr0.7Fe0.7Cr0.3O3−δ cathode layer on GDC

“…Djurado et al [39][40][41][42][43][44][45][46] studied the effects of electrospraying parameters on the microstructures of LSCF cathode layers. Sındıraç et al 47 also studied the similar cathode layers but with different carrier solvents. It has been reported that cathode layers with a reticular structure can be coated on GDC electrolytes by the use of the ESD method that involves spraying a solution containing the properly formulated ionic mixtures constituting the cathode composition.…”

Electrochemical Generation of Mesopores and Residual Oxygen for the Enhanced Activity of Silver Electrocatalysts

“…However, many practical devices such as Zn–air batteries employ highly concentrated electrolytes, in which the ORR kinetics may differ from that in dilute electrolytes. Therefore, we tested the ORR performances of AgO δ /CP and Ag/CP electrodes in a hanging meniscus configuration (Figure S6), which allows atmospheric oxygen to diffuse through the triple phase boundary (TPB). − …”
