A Novel Lanthanum-based Solid Oxide Fuel Cell Electrolyte Composite with Enhanced Thermochemical Stability toward Perovskite Cathode
Lanthanum-based electrolytes for Solid Oxide Fuel Cells (SOFCs) gain extensive attention due to their lower activation energy and low-cost preparation to convert the energy stored in gaseous chemicals into electricity. In this context, a La9.33Si6O26-La0.8Sr0.2Ga0.8Mg0.2O2.55 (LSO-LSGM) SOFC ele...

| description | Lanthanum-based electrolytes for Solid Oxide
Fuel Cells (SOFCs) gain extensive attention due to their lower activation
energy and low-cost preparation to convert the energy stored in gaseous
chemicals into electricity. In this context, a La9.33Si6O26-La0.8Sr0.2Ga0.8Mg0.2O2.55
(LSO-LSGM) SOFC electrolyte composite with various mass ratio LSO:LSGM (w/w)
(5:0, 4:1, 3:2, 2:2, 2:3, 1:4) are successfully prepared for the first time
using different LSO precursors with various mass target of 3g (LSO-LSGMA)
and 5g (LSO-LSGMB), respectively. The result shows that the lower
mass target in the synthesis of LSO induced formation of protoenstatite and
coesite secondary phases on the composite of LSO-LSGM based on XRD, FTIR, and
XPS analysis. The SEM micrograph suggests that agglomeration occurred more in
LSO-LSGMA than in LSO-LSGMB. Generally, the composites
signified high chemical stability on La0.8Sr0.2Co0.6Fe0.4O2.55
(LSCF) cathode based on the XRD analysis. The LSO-LSGMA
composites which contained a high percentage of protoenstatite and coesite
resulted in an additional peak of MgSi2Sr, especially for the sample
with the mass ratio of 41 (LSO-LSGM41) suggesting that the chemical stability
of LSO-LSGMA on LSCF cathode is much lower than LSO-LSGMB. |
