<P>PROBLEM TO BE SOLVED: To ensure sufficient gas permeability and current collecting ability and form a sufficient three-phase interface in an electrode of a fuel cell. <P>SOLUTION: A solid electrolyte layer 20 is formed. A dense layer 22a made of an electrode material having electronic conductivity and catalyst activity accelerating electrochemical reaction is formed on the electrolyte layer 20. Energy giving treatment is applied to the dense layer 22a to make the dense layer 22a porous, and a porous cathode 22 is formed from the dense layer 22a. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
