Abstract

A mixed conductive Pr0.7Sr0.3Fe0.8Al 0.2O3-δ (PSFA) thin film was prepared by using pulsed laser deposition (PLD) and its electrochemical properties have been investigated. A dense PSFA target for PLD was prepared at 1130°C for 10 h. By using the target, 285 nm-thick PSFA thin film was deposited on an 8 mol%Y2O3-doped ZrO2 substrate at 625°C The PSFA thin film was well crystallized and its grain size was in the range of 5 to 10 nm. The PSFA thin film showed an area specific resistance (ASR) of 0.37 Ω·cm2 at 900°C The activation energy of ASR was approximately 1.6 eV at temperature range of 600 to 900°C
