US Patent 7604670 Electrolyte-electrode joined assembly and method for producing the same

NiO particles and YSZ particles are mixed with each other at a predetermined ratio. A binder is added, followed by being dispersed in a solvent to prepare granular particles by a spray drying method. The particles are used to obtain a compact by press forming. A YSZ paste is printed on one end surface of the compact, and the compact and the paste are sintered together to prepare an anode and a solid electrolyte. A paste of La0.6Sr0.4MnO3 is printed on one exposed end surface of the solid electrolyte, followed by being heated to calcine a cathode. Thus, an electrolyte-electrode joined assembly is obtained.
