Description
Summary:This study included two parts: (1) the structural characteristics, chemical stability, thermal expansion coefficient (TEC), chemical bulk diffusion coefficient (Dchem), chemical surface exchange coefficient (kchem), electrochemical performance and single cell performance for LaSrCo1.6Cu0.4O5+δ as an intermediate-temperature solid oxide fuel cells (IT-SOFC) cathode material, and (2) using a pulsed laser technique (PLD) deposited a dense Ce0.8Sm0.2O1.9 (SDC) thin layer on thick SDC as bi-layer electrolyte and infiltrating SDC nanoparticles onto LaSrCo1.6Cu0.4O5+δ skeleton to improve the performance of the single cell. The single cell assembling with 0.5M SDC-infiltrated LaSrCo1.6Cu0.4O5+δ cathode and PLD-deposited SDC/SDC bilayer have shown very good performance at low operating temperatures.
