摘要： A fuel cell includes separators and electrolyte electrode assemblies in a first area between the separators. Each separator includes a first plate and a second plate stacked together to form a second area between the first plate and the second plate. The second area is divided by an outer ridge into a fuel gas channel, and an oxygen-containing gas channel. The fuel gas channel formed in one separator is connected to a fuel gas flow passage in the first area through fuel gas inlets for supplying a fuel gas to anodes. The oxygen-containing gas channel in the other separators is connected to an oxygen-containing gas flow passage in the first area through oxygen-containing gas inlets for supplying an oxygen-containing gas to cathodes.

摘要： Each of separators for sandwiching a plurality of electrolyte electrode assemblies includes a pair of plates. A fuel gas channel and an oxygen-containing gas channel are formed between the plates. First and second circumferential ridges are formed integrally on curved outer sections of the plates to protrude away from each other. Further, outer projections and inner projections are formed integrally on opposite sides of the first and second circumferential ridges to protrude toward each other.

摘要： Ends of heat-transfer plates S1, S2, formed by bending folding plate blanks in a zigzag fashion along folding lines L1, L2, are cut in an angle shape, and flange portions 26 formed by folding apexes of the angle shape are superposed one on another and brazed in a surface contact state, thereby to form combustion gas passage inlets 11 and air passage outlets 16 along the two end edges of the angle shapes. Compared with brazing of separate flange members onto the cut surfaces of the apexes of the angle shapes, this fabrication not only dispenses with precise finishing of the cut surfaces, but also serves to increase the brazing strength.

摘要： A heat exchanger which is constructed such that combustion gas passages 4 for passage of combustion gas and air passages 5 for passages of air are arranged alternately, and the heat exchanger is cut at one end side thereof in an unequal angle configuration to form combustion gas passage inlets 11 and air passage outlets 16, and cut at the other end side thereof in an unequal angle configuration to form combustion gas passage outlets 12 and air passage inlets 15. the combustion gas passage inlets 11 and combustion gas passage outlets 12, through which a combustion gas having a larger volume flow rate passes, are formed on a long side of an angle, and the air passage inlets 15 and air passage outlets 16, through which an air having a smaller volume flow rate passes, are formed on a short side of an angle. Accordingly, it is possible to avoid an increase in pressure loss caused by a volume flow rate difference between a high temperature fluid and a low temperature fluid to reduce pressure loss in the entire heat exchanger.

摘要： First heat-transfer plates S1 and second heat-transfer plates S2 are radially arranged between a larger diameter cylindrical-shaped outer casing 6 and a smaller diameter cylindrical-shaped inner casing 7 to form combustion gas passages 4 and air passages 5 alternately in a circumferential direction, and a multiplicity of projections 22, 23 formed on both surfaces of the first heat-transfer plates S1 and second heat-transfer plates S2 are jointed to one another at tip ends thereof. Pitches P between adjacent projections 22, 23 are changed in a radial direction to make the number of heat transfer units substantially constant in a radial direction to uniformize temperature distributions on the first heat-transfer plates S1 and second heat-transfer plates S2 in the radial direction, thereby avoiding a decrease in heat exchanging efficiency and generation of unwanted thermal stress.

摘要： In the case where a partition for partitioning a combustion gas passage inlet 11 from an air passage outlet 16 is defined by a plate 8 attached by brazing to end surfaces of a plurality of heat-transfer plates S1, S2 in a heat exchanger 2, durability of the brazed portions are prevented from being degraded due to a load F acting on the plate 8 by a pressure differential between a combustion gas and air. Thus a bonding base plate 26 is attached by brazing to the end surfaces of the heat-transfer plates S1, S2 with the front surface of the bonding base plate 26 brazed to the rear surface of a bonding flange 28, which is formed by bending an end of the plate 8 by right angles, and a bonding flange 27 having an L-shaped cross section is attached by brazing to an underside of the plate 8 and the front surface of the bonding base plate 26. Accordingly, the bonded portions are increased in rigidity to ease stress concentration, thus enhancing durability.
