<P>PROBLEM TO BE SOLVED: To provide a fuel battery single cell which excels in output density and is therefore suitable for direct flame type fuel batteries. <P>SOLUTION: The fuel battery single cell comprises a first fuel electrode layer (A) 21 porously formed with metal oxide and a solid electrolyte, a second fuel electrode layer (B) 22 porously formed with metal oxide and a solid electrolyte and having a smaller porosity than the first fuel electrode layer (A) 21, a solid electrolyte layer (C) 23 formed with a slid electrolyte, and an air electrode layer (D) 24, the layers being laminated one on another in order of (A), (B), (C) and (D). The solid electrolyte included in the first fuel electrode layer (A) 21 is 8YSZ, and those included in the solid electrolyte layer (C) 23 and the second fuel electrode layer (B) 22 are ScSZ. <P>COPYRIGHT: (C)2013,JPO&INPIT |
