  • Publication number: 20230420691
    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.

  • Patent number: 11616239
    Abstract: Disclosed is a method for manufacturing a large-area thin-film solid oxide fuel cell, the method including: preparing an anode support slurry, an anode functional layer slurry, an electrolyte slurry, and a buffer layer slurry for tape casting; preparing an anode support green film, an anode functional layer green film, an electrolyte green film, and a buffer layer green film by tape casting the slurries onto carrier films; staking the green films, followed by hot press and warm iso-static press (WIP), to prepare a laminated body; and co-sintering the laminated body.
