Abstract
The present invention relates to a core-shell structured composite powder for a solid oxide fuel cell (SOFC) and more particularly, to a core-shell structured composite powder for a SOFC having a new structure in which nickel, zirconium and yttrium are stably formed in a core shell structure to improve sinterability and conductivity while preventing a fuel electrode from being deformed due to coarsening and contraction of nickel during operation.
Claims6
A core-shell structured composite powder for a solid oxide fuel cell (SOFC) comprising:
- a core portion composed of at least one of Ni particles or NiO particles;
- and
- a shell portion formed around the core portion and composed of at least one of yttrium, zirconium, cesium, cerium, scandium, lanthanum, strontium, gallium, magnesium and gadolinium.
Dependencies are inferred from the claim text.
