COMPOSITE CATHODES FOR SOLID OXIDE FUEL CELL, SOLID OXIDE FUEL CELL COMPRISING THE SAME AND PREPARATION METHOD THEREOF

摘要

The present invention relates to a composite cathode for a solid oxide fuel cell, the solid oxide fuel cell including the same, and a manufacturing method thereof, wherein the composite cathode enhances oxygen reduction activity at low and middle temperatures by coating and dispersing Ag and CeO2 on a sintered oxide cathode layer having aperovskite structure and improves durability.
