The present invention relates to a power generating apparatus using a solid oxide fuel cell. A plurality of solid oxide fuel cells, each comprising a solid oxide substrate, a porous cathode electrode layer, and a porous anode electrode layer, are stacked vertically and housed inside a walled structure. A mixture gas is supplied to each solid oxide fuel cell from above. An exhaust gas discharged from each fuel cell is burned in a space below each fuel cell, producing a flame. Each fuel cell is heated by this flame.

Metallic meshes M1, M2 are provided on the cathode electrode layer side and the anode electrode layer side of the electrolyte substrate, respectively. A metallic mesh is plane-pressed onto the both sides of an electrolyte sheet having a predetermined shape prepared from an electrolyte green sheet. A cathode electrode paste layer is formed on one side of the electrolyte sheet while an anode electrode paste layer is formed on the other side of the electrolyte sheet. The electrolyte sheet, the cathode electrode paste layer and the anode electrode paste layer are then integrally fired. When the firing is terminated, a solid oxide fuel cell is completed.

The present invention relates to a power generating apparatus that generates electric power using a solid oxide fuel cell by directly exposing the fuel cell to a premixed gas combustion flame formed in an infrared gas space heater. The solid oxide fuel cell is built into an infrared radiator in such a manner as to face a burner of the gas space heater, and is supported at a prescribed angle of tilt. An anode electrode layer, which is directly exposed to the flame produced by the burner, is kept in a fuel-rich condition, while a cathode electrode layer is exposed to the atmosphere and thus kept in an air-rich condition.

A solid oxide fuel cell that directly utilizes a flame according to the present invention has a solid oxide substrate, a cathode electrode layer formed on one surface, and an anode electrode layer 3 formed on the opposite surface and a platinum mesh is embedded in the entire surfaces of the solid cathode electrode layer and the anode electrode layer. An oxide layer covers the entire periphery of the solid oxide substrate from the end part of the cathode electrode layer to the end part of the anode electrode layer. Due to the platinum mesh and the oxide layer, thermal shock due to rapid heating by a flame is alleviated and cracking in the solid oxide substrate is prevented from occurring.
