SOLID ELECTROLYTE FUEL CELL

摘要

Disclosed is a noble solid electrolyte fuel cell comprising a generating layer [5], an interconnector layer [9], and a support layer [10,11] disposed between the generating layer and the interconnector. The interconnector layer comprises a fuel electrode and an interconnector material and an oxygen electrode. The support layer forms a fuel passage and an oxidizer passage, and supporting rods [15] for gas sealing are disposed at both ends of the support layer. Also, a sealing film is cemented to the contact surfaces of the supporting rod between the generating layer and the interconnector, and this sealing film becomes soft or half melted during the operation of the fuel cell. This construction provides better sealing of gases even under large temperature differences and improved cell performances. Also, the use of finer particles near the surface of the solid electrolyte only is disclosed.
