Provided is a solid oxide fuel cell having a service life of approximately 90,000 hours, a level required to encourage the widespread use of SOFC. The solid oxide fuel cell is provided with a solid electrolyte layer, an oxygen electrode layer provided on one side of the solid electrolyte layer, and a fuel electrode layer provided on the other side of the solid electrolyte layer. The oxygen electrode layer is made from a material containing iron or manganese, and the solid electrolyte layer contains an yttria-stabilized zirconia solid electrolyte material having a lanthanoid oxide dissolved therein.

Solid oxide fuel cell

Disclosed is an electrically conductive member for electrically connecting a plurality of solid oxide fuel cells in series and/or parallel to assemble a fuel-cell stack. The electrically conductive member according to the present invention comprises a metal sheet having a three-dimensional porous structure of a continuous skeleton. The electrically conductive member according to the present invention is three-dimensionally strong and is highly elastic and resilient. Therefore, the thickness of the electrically conductive member can be easily re-regulated in the regulation of spacing between the fuel cells. Further, even after baking or power generation, the electrically conductive member is not sintered, and separation easily takes place in the folded interface, and, thus, excellent maintainability can be realized.
