Enhanced thermal stability and electrical characteristics of sputtered Pt thin film for low temperature solid
oxide fuel cells
Kang-Yu Liu and Pei-Chen Su
Nanyang Technological University, Singapore
T
his work demonstrates a thermal stable nanoporous cathode with atomic layer deposited ZrO
2
capping and Pt-Ni alloying to
effectively inhibit the thermal agglomeration of nanoporous Pt. The ZrO
2
capping is found to confine the surface nanoporous
morphology and Pt alloying with Ni is found to constrain its underlaying microstructure at high temperature operation of 450 °C. The
output current using ZrO
2
capped PtNi cathode has a significant improved stability, comparing with pure Pt cathode. The material
characterization and electrical impedance spectrum were discussed towards the enhanced thermal stability and electrochemical
behaviors.
