ABSTRACT:
The invention relates to compositions and composite particles that may be employed as anode materials for Solid Oxide Fuel Cells (SOFCs). The invention particularly relates to novel metallic SOFC anode materials, which preferably comprise metallic nickel (Ni), copper (Cu), especially if the Ni/Cu oxide has been stabilized with yttrium (Y) oxide (e.g., Y2O3) and/or zirconium (Zr) oxide (e.g., ZrO2) composition(s) (“YSZ”). Such compositions may additionally comprise a cerium (Ce) oxide (such as CeO2) (e.g., Ni/YSZ/CeO2). The invention particularly concerns such compositions and particles produced through the use of direct deposition or Flame Spray Pyrolysis so as to provide a controlled morphology and chemical composition.
