Study Results from Yeungnam University Provide New Insights into Nanocrystals
June 24th, 2011
"A nanocrystalline powder with a lanthanum based iron- and cobalt-containing perovskite, La0.6Sr0.4Co0.2Fe0.8O3-delta (LSCF), is investigated for solid oxide fuel cell (SOFC) applications at a relatively low operating temperature (600-800 degrees C). A LSCF powder with a high surface area of 88 m(2) g(-1), which is synthesized via a complex method with using inorganic nano dispersants, is printed onto an anode supported cell as a cathode electrode," researchers in Gyongsan, South Korea report.
"A LSCF cathode without a sintering process (in situ sintered cathode) is characterized and compared with that of a sintering process at 780 degrees C (ex situ sintered cathode). The...
