<P>PROBLEM TO BE SOLVED: To provide a cell stack and a fuel battery which can improve bonding strength of a plate collector member to a fuel battery cell. <P>SOLUTION: In the cell stack, respective plate collector members 20 are placed in spaces between a plurality of fuel battery cells 1, in each of which a solid electrolyte layer 3 is sandwiched between an oxygen electrode layer 4 and a fuel electrode layer 2, and the plate collector member 20 is bonded to the oxygen electrode layer 4 of the fuel battery cell 1 for the fuel battery cell 1 and the plate collector member 20 to be electrically connected. The oxygen electrode layer 4 has a first oxygen electrode layer 4a placed on the solid electrolyte layer 3 and a second oxygen electrode layer 4b placed on the first oxygen electrode layer 4a. The first oxygen electrode layer 4a is made of conductive ceramic particles in an average size less than the particles of the second oxygen electrode layer 4b, one main side surface of the plate collector member 20 is bonded to the first oxygen electrode layer 4a, and a side surface of the plate collector member 20 is bonded to the second oxygen electrode layer 4b. <P>COPYRIGHT: (C)2008,JPO&INPIT |
