Method for manufacturing protonic ceramic fuel cell and protonic ceramic fuel cell manufactured by given method

A method for manufacturing a protonic ceramic fuel cell, the method comprising:

• a first step of manufacturing an anode support slurry, an anode reaction layer slurry, and an electrolyte slurry;
• a second step of performing tape-casting of the anode support slurry, the anode reaction layer slurry, and the electrolyte slurry manufactured in the first step and manufacturing an anode support tape, an anode reaction layer tape, and an electrolyte tape;
• a third step of forming a lamination structure by sequentially laminating the anode support tape, the anode reaction layer tape, and the electrolyte tape manufactured in the second step;
• a fourth step of sintering the lamination structure formed in the third step through two steps of heat treatments at respective temperatures different from each other;
• a fifth step of forming a cathode at a surface of the lamination structure sintered in the fourth step at which the electrolyte tape is positioned;
• and
• a sixth step of co-sintering the lamination structure having the cathode formed in the fifth step,
• wherein the fourth step is performed through a first heat treatment and a second heat treatment which are executed at respective temperatures different from each other, and the first heat treatment is executed at a temperature ranging from 800° C. to 1,000° C. for 12 hours to 20 hours.
