Abstract: There is provided a method for manufacturing a protonic ceramic fuel cell, including: 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 respective slurries 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.
