Solid oxide cell and manufacturing method thereof

Abstract

A solid oxide cell includes a solid oxide electrolyte, and a fuel electrode disposed on one side of the solid oxide electrolyte and an air electrode disposed on the other side thereof. The fuel electrode includes alloy oxide particles of nickel (Ni) and a heterogeneous metal alloyable therewith and a solid oxide electrolyte material, and when an atomic percentage (at %) of the heterogeneous metal to all atoms in a center region of the alloy oxide particle is Mcore and an atomic percentage (at %) of the heterogeneous metal to all atoms in a surface region of the alloy particle is Msurface 10×Mcore<Msurface.
