A process for producing a solid oxide type fuel battery cell, characterized by including the porous electrolyte layer forming step of applying an electrolyte layer forming slurry containing an electrolyte substance powder and a pore forming agent onto a surface of electrolyte substrate and subsequently firing the electrolyte substrate to thereby obtain an electrolyte substrate furnished with a porous electrolyte layer; and the electrode layer forming step of applying an electrode layer forming slurry containing an electrode substance powder, a powder of electrode substance powder mixed with electrolyte substance powder, or a composite powder of electrode substance and electrolyte substance to the surface of the porous electrolyte layer of the electrolyte substrate furnished with porous electrolyte layer, and subsequently firing the electrolyte substrate furnished with porous electrolyte layer to thereby obtain an electrolyte substrate furnished with porous electrolyte layer filled with electrode substance and electrode layer. Thus, there can be provided a process for producing a solid oxide type fuel battery cell, wherein the three-phase interface of the electrolyte layer can be increased and wherein any drop of conductivity of the electrolyte layer can be slight. |
