METHOD FOR MANUFACTURING PROTON CONDUCTING OXIDE FUEL CELL
PROBLEM TO BE SOLVED: To provide a method for manufacturing a proton conducting oxide fuel cell, which enables the formation of a dense electrolyte layer without causing the decrease in electric property, such as the interface delamination of an electrolyte layer and a positive electrode or the increase in interface resistance, and which is advantageous for achievement of the increase in area and mass production.SOLUTION: A method for manufacturing a proton conducting oxide fuel cell comprises the steps of: synthesizing a sintering assistant represented by BaMOor BaY2MO(where M is Ni, Cu or Zn); preparing a negative electrode layer including a yttrium-doped barium cerate-zirconate (BCZY) and a nickel oxide (NiO) which is a transition metal oxide; dispersing the yttrium-doped barium cerate-zirconate (BCZY) in solvent to prepare an electrolyte paste; screen printing the electrolyte paste on the negative electrode layer to form an electrolyte layer; and sintering the negative electrode layer and the electrolyte layer concurrently.SELECTED DRAWING: Figure 1
