- -CORE-SHELL POWDER OF SOLID OXIDE FUEL CELL AND FABRICATION PROCESS THEREOF AND CELL-STACK OF SEGMENTED-IN-SERIES SOLID OXIDE FUEL CELL BY USING THEREOF

摘要

The present invention uses a nickel (Ni) -metal (Fe, Co, Cu, etc.) alloy powder as a core for use as a solid oxide fuel cell (SOFC) fuel electrode and uses a yttria stabilized zirconia (YSZ) A nanoscale core - shell fuel electrode was prepared using a reducing agent and a surfactant. The prepared powders have a uniform nano size and form a nanocomposite structure having mutually continuous networks. The long - term stability, the thermal cycle stability and the redox stability are remarkably improved by suppressing the volume shrinkage and the carbon deposition in the reducing atmosphere . In addition, when the liquid slurry is used in the nano-size powder coating, it is impossible to uniformly distribute or form a thickness due to the intergranular coagulation phenomenon. Therefore, a solid-state core-shell fuel electrode transfer sheet is manufactured and laminated, To a method of manufacturing a battery cell stack.
