Planar solid oxide fuel cell

Abstract

To provide a flat plate solid-oxide fuel cell in which the occurrence of considerable temperature difference in the surface direction of the cell can be suppressed with simple configuration.SOLUTION: A flat plate solid-oxide fuel cell comprises a cell 2, interconnectors 31 and 32 and a heat transfer plate 4. The interconnector 31 at a fuel electrode side is disposed along a plate surface of the cell 2 at the side of a fuel electrode layer 21 and constitutes a flow channel 310 of fuel gas. The interconnector 32 at an air electrode side is disposed along a plate surface of the cell 2 at the side of an air electrode layer 23 and constitutes a flow channel 320 of air. The heat transfer plate 4 has thermal conductivity higher than thermal conductivity of the interconnector 31 at the fuel electrode side and the interconnector 32 at the air electrode side. The cell 2, the interconnector 31 at the fuel electrode side, the interconnector 32 at the air electrode side and the heat transfer plate 4 are laminated in such a manner that a plate surface of the interconnector 31 at the fuel electrode side or the interconnector 32 at the air electrode side is brought into surface contact with a plate surface of the heat transfer plate 4.SELECTED DRAWING: Figure 1
