Dense, crack-free, yttria-stabilized-zirconia (YSZ) films of up to 100 microns thick were deposited on nickel oxide/YSZ substrates and porous La{sub 0.85}Sr{sub 0.15}MnO{sub 3} (LSM) substrates. The new technique was also used to deposit a compositionally-graded film of YSZ and Ce{sub 0.8}Y{sub 0.2}O{sub 2} (CYO), …
Introduction. Yttria stabilized zirconia is a ceramic material. It is formed in a bid to stabilize the cubic crystal structure of zirconium dioxide at room temperature. To stabilize the crystal cubic structure of zirconium dioxide, manufacturers add yttrium oxide which is also known as yttria. Yttria is not the only material that can be added ...
Nickel/yttria stabilized zirconia (Ni/YSZ) is generally used as the SOFC anode material due to its low cost [16]. On the other hand, LaFeO 3 LaCoO 3, LaMnO 3, and La 0.84 Sr 0.16 Co 0.3 Fe 0.7 O 3-LSCFe 7 can be used as SOFC cathode materials [17,18]. SOFC bipolar plates can be made of cermet, doped ceramic, or metallic materials.
