A process for producing a cell for solid oxide fuel cells comprising a porous electrolyte layer-forming step of obtaining an electrolyte substrate in which a porous electrolyte layer is formed by applying a slurry for forming an electrolyte layer containing an electrolyte substance powder and a pore-forming agent to the surface of an electrolyte substrate and burning the electrolyte substrate, and an electrode layer-forming step of obtaining an electrolyte substrate in which an electrode substance-filled porous electrolyte layer and an electrode layer are formed by applying a slurry for forming an electrode containing an electrode substance powder, a mixture of an electrode substance powder and an electrolyte substance powder, or a composite material powder of an electrode substance and an electrolyte substance, onto the surface of the porous electrolyte layer of the electrolyte substrate on which the porous electrolyte layer is formed, and burning the electrolyte substrate in which the porous electrolyte layer is formed. According to the present invention, a process for producing a cell for solid oxide fuel cells which can increase the three-phase interface of the porous electrolyte layer and exhibits only a small conductivity reduction of the electrolyte layer can be obtained. |
