Abstract
Disclosed is a method of manufacturing a cathode for a solid oxide fuel cell (SOFC) including preparing an electrode composition containing urea, ultrasonically spraying the electrode composition onto a GDC scaffold, and drying the scaffold. By using urea, calcination (≥700° C.) after each infiltration cycle can be omitted, the next infiltration cycle is performed immediately after the drying (≤100° C.), and thus the cathode manufacturing process time can be greatly reduced. Disclosed is also a solid oxide fuel cell including an anode support, an anode functional layer disposed on the anode support, an electrolyte disposed on the anode functional layer, and a cathode disposed on the electrolyte, wherein the cathode is formed by ultrasonic spraying using an electrode composition containing urea.
