Abstract
A low temperature (≤500 °C) process for fabricating nano structured porous LSM–YSZ composite films, 35 μm in thickness, for use as a cathode in the low temperature solid oxide fuel cell (LT-SOFC) was developed using a ceramic–polymer composite powder and an aerosol deposition (AD) process. Polyvinylidene fluoride (PVDF) polymer powder was mixed with LSM and YSZ ceramic powders, as a pore former to prepare the composite powder for AD. The deposited LSM–YSZ composite ceramic film maintained good adhesion with the YSZ electrolyte and showed >40% porosity with a particle and pore size of 10–100 and 100–200 nm, respectively. The peak power density of the YSZ electrolyte-based, anode-supported-type cell with the nano-structured LSM–YSZ cathode produced by AD was 140 mW/cm2 at 600 °C.
