摘要： An improved structure of a solid oxide electrolyte fuel cell (SOFC) is disclosed. A generating layer in the SOFC consists of three layers of a fuel electrode, an oxide layer and an oxygen electrode, and is shaped into a dimpled structure having recessed portions on its both surfaces. Protruded portions on the side of the fuel electrode are electrically bonded with an interconnector layer via a first conductive adhesive, while protruded portions on the side of the oxygen electrode of another generating layer are electrically bonded with the same interconnector layer via a second conductive adhesive. A plurality of generating layers and a plurality of interconnector layers are alternately stacked and they are electrically bonded in the above-described manner. Preferably the first conductive adhesive is made of material common to the fuel electrode and the second conductive adhesive is made of material common to the oxygen electrode. Owing to the improved structure, occurrence of lateral flows of electrons in the interconnector layers having a large resistance can be suppressed, hence an electrical resistance can be reduced, and also amounts of materials of the oxygen electrode and the fuel electrode can be made small.

摘要： A power generation system with flat fuel cells of solid electrolyte construction permits the building up of a large capacity system. There are a train of pile units of flat fuel cells of solid electrolyte disposed in a horizontally extending fuel gas duct. The gas fuel duct supplies to the train of pile units of flat fuel cells fuel gas. Each of said pile units of flat fuel cells has a horizontal flat flow path for the fuel gas disposed above each fuel-side porous electrode sheet of the fuel cell opening freely at two path ends on the opposing side faces of the pile unit. There is a horizontal flat flow path for the oxidant gas disposed beneath each oxygen-side porous electrode sheet separated from the fuel gas flow paths and each connected at two path ends to either a supply line or to an exhaust line for the oxidant gas. There is an after-burning region disposed downstream of said train of pile units of flat fuel cells, for burning at least a part of the spent fuel gas which has passed through the fuel cell using at least a part of the spent oxidant gas which has passed through the fuel cell, for generating a heat of combustion for use for preheating at least one of the feed gases to be supplied to the fuel cell.

摘要： A noble solid electrolyte fuel cell includes a generating layer (5), an interconnector layer (9), and a support layer (10) disposed between the generating and interconnector layers. The interconnector layer comprises a fuel electrode (6), an interconnector material (7) and an oxygen electrode (8). The support layer (10) forms a fuel passage and an oxidizer passage, and supporting rods (15, 102) for gas sealing are disposed at both ends of the support layer. A sealing film (110) is cemented to the contact surfaces of the supporting rods (15, 102) between the generating layer and the interconnector layer, and this sealing film becomes soft or half melted during the operation of the fuel cell. This construction provides improved cell performances due to better sealing of gases even under large temperature differences. The use of finer particles near the surface of the solid electrolyte only is also disclosed.
