- •
LSCF thin films are prepared using pulsed laser deposition on GDC-buffered YSZ.
- •
LSCF microstructure can be tailored by modifying the surface morphology of GDC.
- •
Oxygen surface exchange property depends on microstructure of LSCF.
- •
Higher surface exchange coefficient k* is obtained for nanograined LSCF thin film.
