- BaZr0.85Y0.15O3-δ (BZY) thin film was prepared by pulsed laser
deposition (PLD) at of 400℃ and 700℃ and performance was
compared as free-standing electrolyte of micro ceramic fuel cells.
Structural and electrochemical analyses were conducted using
scanning electron microscopy (SEM) and a customized fuel cell
measurement set-up, respectively. As a result, we have identified
that chemical stability of PLD BZY deposited at 700℃ (PLD
BZY-700) was improved showing stable open circuit voltage
(OCV) close to 0.9V compared to one made at 400℃ (PLD BZY-
400). Fully densified structure was identified in PLD BZY-700
with clear separation of electrodes.
