文摘
- •
Nano-granular GDC was fabricated on cathode side of electrolyte by AACVD.
- •
It was confirmed that deposition temperature determined the grain size in AACVD.
- •
Optimized AACVD–GDC treatments enhanced power of fuel cells by up to 50%.
- •
High grain boundary density of the AACVD–GDC layers enhanced ORR kinetics.
