MANUFACTURING METHOD OF LSCF POWDER AND CELL HAVING THE POWDER FOR SOLID OXIDE FUEL CELL

摘要

Disclosed is a method for preparing LSCF powder for cathode of a solid oxide fuel cell that can operate at medium and low temperatures. LSCF powder manufacturing method for a cathode of a solid oxide fuel cell, at least one selected from the group consisting of at least one salt selected from the group consisting of salts containing lanthanum (La), salts containing strontium (Sr). Dissolve in distilled water at least one fourth salt selected from the group consisting of a second salt, a salt comprising cobalt (Co) and at least one third salt selected from the group consisting of salts containing iron (Fe) To form an aqueous metal salt solution, mixing a chelating agent with the aqueous metal salt solution to form a mixture, heating the mixture to a first temperature, and adding alcohol to the heated mixture, followed by a second Heating to a temperature to form a sol, drying at a third temperature in the sol to form a polymer resin, heat treating the polymer resin, and heat treatment It may comprise the step of calcining the finished polymer resin to form a LSant (Lanthanum Strontium Cobalt Ferrite) powder.
