<P>PROBLEM TO BE SOLVED: To secure a circulation passage of fuel gas, a conduction path of an electric charge and sufficient strength in an anode side electrode constituting an electrolyte-electrode assembly. <P>SOLUTION: An electrolyte-electrode assembly 10 includes an anode side electrode 12 comprising a porous body having a porosity of 20-40% and a major axis of 1-4 μm. A differential pore volume of the anode side electrode 12 obtained by a mercury porosimeter method has a maximum at a pore diameter of 1 μm or less (a mode diameter is 1 μm or less). A large diameter pore 24 included in the anode side electrode 12 is formed using a pore forming material made of a resin material such as polymethyl methacrylate. A flattening layer 14 and an intermediate layer 18 may be disposed, as necessary, between the anode side electrode 12 and a solid electrolyte 16 and between the solid electrolyte 16 and a cathode side electrode 20, respectively. <P>COPYRIGHT: (C)2013,JPO&INPIT |
