<P>PROBLEM TO BE SOLVED: To provide a composite ceramic material that has high distributability and composition controllability of a plurality of kinds of oxide particles, many three-phase interfaces, and high oxygen ion generation property, a method of manufacturing the composite ceramic material, and a solid oxide type fuel cell. <P>SOLUTION: This composite ceramic material includes a three-dimensional network skeleton structure where zirconia particles made of yttria-stabilized zirconia are bonded, and oxide represented by A<SB POS="POST">1-x</SB>B<SB POS="POST">x</SB>C<SB POS="POST">1-y</SB>D<SB POS="POST">y</SB>O<SB POS="POST">3-δ</SB>is bonded to the surface of the network skeleton structure. In the formula, A is one or more elements selected from a group of La, Sm, and Fe, B is one or more elements selected from a group of Sr and Ni, C is one or more elements selected from a group of Co and Mn, D is one or more elements selected from a group of Fe and Ni (this is different from A), 0.2≤x≤0.9, 0≤y≤1, 0≤δ≤1, and a certain oxygen defect is contained when 0<δ. <P>COPYRIGHT: (C)2013,JPO&INPIT |
