Current Research

Craig's current research focuses on fabrication of Ni and yttria-stabilized zircona (YSZ) cermets by atmospheric plasma spraying for use as anodes in solid oxide fuel cells. Three different spray processes are used, which differ in the feedstock material fed to the plasma torch. These are spray-dried powders of NiO and YSZ, NiO and YSZ powders in an aqueous suspension, and finally a solution containing Ni, Zr, and Y precursors. Each of these spray processess yield distint microstructural features. Craig is focussed on understanding the affect these different microstructures have on the performance of the SOFC.
