<P>PROBLEM TO BE SOLVED: To improve power generation efficiency of a unit cell for a solid oxide fuel battery. <P>SOLUTION: Between a fuel electrode 1 and an electrolyte 3, a fuel electrode intermediate layer 2 is provided of which the porosity is lower and the thickness is less than the fuel electrode 1. Furthermore, between the electrolyte 3 and an air electrode 5, an air electrode intermediate layer 4 is provided of which the porosity is lower and the thickness is less than the air electrode. Thus, fuel utilization efficiency can be improved by excellent gas supply and battery voltage efficiency can be improved by enlarging a three-phase interface compatibly, thereby improving power generation efficiency as a result. <P>COPYRIGHT: (C)2012,JPO&INPIT |
