<P>PROBLEM TO BE SOLVED: To provide a fuel electrode for a solid oxide fuel cell which does not produce deteriorated articles and does not produce aggregation between metal particles while maintaining superior long-term stability, by introducing a finely divided material which is active to carbon deposition resistance or electrochemical reaction of a fuel gas, to the portion that the material can exert its action most effectively as a catalyst in the skeletal structure of the porous fuel electrode. <P>SOLUTION: The skeletal structure of the porous fuel electrode composed of a plurality of layers which have different porosity and consist of metal oxide having oxygen ion conductivity and a metal or its oxide fine particles having electron conductivity is formed on the surface of solid electrolyte, and into the layer whose porosity in the skeletal structure is large compared with that of the other layers, a solution containing a compound which may be an active material or a carbon deposition resistant material by heat treatment is injected and heat-treated, thus dispersing the active material as the oxide and the metal into the layer having large porosity . <P>COPYRIGHT: (C)2005,JPO&NCIPI |
