<P>PROBLEM TO BE SOLVED: To provide a solid oxide type fuel cell capable of equalizing current density and temperature distribution in the cell, and of significantly reducing stress generated by a thermal expansion difference among respective constituent members; and to provide a solid oxide type fuel cell stack having excellent space saving capability and high output density and capable of improving gas sealing capability because gas sealing and electrical connection are carried out in different places. <P>SOLUTION: This cell 1 has a structure equipped with: a fuel electrode substrate; fuel gas introduction holes; fuel gas supply tubes 4 inserted into the fuel gas introduction holes; a fibrous conductive material; a solid electrolyte layer and an air electrode layer 8 formed over the upper surface, undersurface and the side surface of the fuel electrode substrate; and gas sealing parts 9a and 9b for sealing the front surface and the rear surface. This stack 11 has a structure wherein a plurality of the cells 1 are stacked by interlaying collectors 12; and each collector 12 has a three-layer structure comprising an upper conductive layer, an insulation layer and a lower conductive layer, and is formed into a shape having a corrugated form or having a plurality of uneven parts. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
