Aerosol deposition (AD) is a promising process for preparation of SOFC cells and stacks’ component because it has low processing temperature to minimize the adverse interfacial reactions during cell production and flexibility of microstructure modification from gas-tight dense structure to porous structure with nano-scaled composites on various anode structure including porous metal support. Since 2007, our group has been working on development of AD process for SOFC application including nano-structured electrolytes and cathodes coatings [1-3], diffusion barrier layer preparation for large-area cells up to 40 x 25 cm2 [4], oxidation resistive layer fabrication for metallic interconnects [5,6], and robust and high performance metal-supported SOFCs fabrication on porous FeCr alloy support [7]. This presentation will sum-up those research results and gives our up-to-date results and a prospect.
