<P>PROBLEM TO BE SOLVED: To provide a solid oxide fuel cell hardly generating counter electromotive force on the back and front of a connector, and in addition, making manufacture easy when integral sintering is performed, and to provide a method of manufacturing the same. <P>SOLUTION: A solid electrolyte 7 is made of an Sc stabilized zirconia solid solution having oxygen ion conductivity for example, a ceramic substrate 13 of an interconnector 5 and a ceramic substrate 21A, 21B of an outside connector 6 are made of a ceramics material having no oxygen ion conductivity ( an oxygen ion insulating ceramics material). Specifically, ceramics substrates 13, 21 of both connectors 5, 6 are composed of at least SiO<SB>2</SB>and RO out of SiO<SB>2</SB>, Al<SB>2</SB>O<SB>3</SB>, and RO (R: Mg, Ca, Sr, Ba), and 20-80 mol SiO<SB>2</SB>, 0-50 mol% Al<SB>2</SB>O<SB>3</SB>, and 20-80 mol RO are contained. <P>COPYRIGHT: (C)2009,JPO&INPIT |
