Figure 4.5. (a) Short term stability measurement of PBSCF infiltrated symmetrical cell and (b) microstructure after the stability test at 600 oC
Figure 4.5 exhibits the impedance of symmetrical cell with PBSCF infiltrated cathode for over 100 hours. During the test, symmetrical cell shows stable impedance without observable degradation.
Additionally, the microstructure of the cathode still maintains the porous morphology without detectable agglomeration on the surface, demonstrating enhanced electrochemical performance without observable degradation.
