COMPOSITE ANODE FOR A SOLID OXIDE FUEL CELL WITH IMPROVED MECHANICAL INTEGRITY AND INCREASED EFFICIENCY

摘要

A composite anode for a solid oxide fuel cell (SOFC), comprising an anode support layer (ASL) of Ni- YSZ and an anode functional layer (AFL) of Ni-GDC, displays enhanced mechanical stability and similar or improved electrical efficiency to that of a Ni-GDC ASL for otherwise identical SOFCs. A SOFC employing the composite anode can be used for power generation at temperatures below 700 °C, where the composite anode may include a second AFL of GDC disposed between the Ni-GDC layer and a GDC electrolyte.
