<P>PROBLEM TO BE SOLVED: To improve an electrical jointing properties, on an interface between a collector layer and an active layer structuring an air electrode. <P>SOLUTION: The air electrode 103 is provided with at least an active layer 131 formed on one of the surface sides of an electrolyte layer 101; a first collector layer 132 formed on and in contact with the active layer 131; and a second collector layer 133 formed on and in contact with the first collector layer 132. The active layer 131 constituted of a powdered sintered body consists of a material having ionic conductivity; the first collector layer 132 is constituted of a powdered sintered body, with an average particle diameter of less than 0.8 μm and consisting of a material having electron conductivity; and the second collector layer 133 is constituted of a powdered sintered body, with an average particle diameter of more than 0.8 μm and consisting of a material having electron conductivity. <P>COPYRIGHT: (C)2011,JPO&INPIT |
