摘要： PROBLEM TO BE SOLVED: To provide a solid electrolyte fuel cell having a stable gas sealing function and a heat cycle resistance function eve in the case of use over a long-term at approximately 1000 deg.C. SOLUTION: A cell 5 and a gas separator 3 are jointed to each other with a bond mainly composed of MgO, MgAl2 O4 and ZrO2 . In this case, the jointed surface of the cell 1 and the gas separator 3 is coated with the slurry of jointing material powder and, then, backed under pressure. Alternatively, the green sheet made of a jointing material is laid on the jointed surface and, then, this jointed surface is backed under pressure. As a joint layer is made of ceramic material stable at high temperature, deterioration hardly takes place during the operation of a fuel cell. Also, the joint layer contains ZrO2 as the electrolyte constituent material of the cell 5 and MgO and MgAl2 O4 as the constituent material of the gas separator 3, and, therefore, shows good compatibility with both of the cell 5 and the separator 3. Furthermore, the thermal expansion coefficient of the jointed part well agrees to the thermal expansion coefficients of the cell 5 and the gas separator 3.

摘要： PURPOSE:To provide a jointed body of high strength and high function having notably high joining strength and excellent in sealing property, etc., by easily and firmly joining the surfaces to be jointed even when they are the non-smooth ones of members to be jointed without doing machining before joining, etc., in joining ceramics members with each other or a ceramics member and a metal member. CONSTITUTION:A ceramics member 1 and a metal member or ceramics member 2 are abutted on each other through an intermediate material 3 and heated. As the intermediate material 3 is used a material which has easier deforming property than the members to be jointed 1, 2 at joining temp. and is deformed following the shape of the members to be jointed 1, 2 at the joining temp. This causes the smoothing treatment of the jointed surface before joining to be unnecessary. Since the jointed surface is a non-smooth one, effective jointed area is increased. Anchoring effect of the intermediate member 3 and the members to be jointed 1, 2 enables a firm jointed body. Thus a jointed body excellent in high temp. strength and sealing property is obtained.

The compound (iii) has a composition similar to that of the component (a) or component (b) or between both components. The component (a) is immersed in the component (c) to form a bonding layer which is a deposition layer composed of the components (i) to (iii) and having the composition gradually varying from the composition of the component (a) to the composition of the component (b) corresponding to the position of the component (a) toward the component (b). The component (b) to be bonded is brought into contact with the bonding layer and hot-pressed to bond the component (a) and the component (b).

摘要： PURPOSE:To eliminate a warping of a burned member and to get a flat burned member having a high degree of flatness by a method wherein a bogie within a tunnel furnace is moved to perform a burning operation and the burned member is held between a table and a loading weight plate near a burning region by lifting up the table. CONSTITUTION:A tunnel-like furnace 14 is mounted on a floor 1 through a furnace supporting frame 12. A bogie passed through a preheating zone approaches a burning zone, where a caster 30 is rotated along an ascending slope 36 to cause a stem 24 to be pushed up and a table 28 is also gradually pushed up. As the caster 30 approaches a raised portion 40, a burned member is pushed against a lower surface of a loading weight plate 34. Then, under a condition in which the table 28 is lifted up to its upper lifting limit position, the loading weight plate 34 is floated up from a weighting plate mounting table 32, resulting in that a weight of the loading weight plate 34 is fully applied to a flat plate-like burned member on the table 28. Due to this fact, the burned member is burned while being press held between the loading weight plate 34 and the table 28.

摘要： PURPOSE:To enhance the output density of a fuel cell without lowering mechanical strength and to enhance the productivity and serviceability of the fuel cell by arranging the coplanar unit cells of a unit cell collective set so that adjacent cells have different polarities. CONSTITUTION:A fuel cell comprises a number of unit cell collective sets 9 stacked on stop another via gas passage members 11 each having a manifold through hole 14, each of the cell sets 9 having a plurality of flat units cells 1 arranged coplanar with one another using a cell frame portion 6 having a manifold through hole 14. The coplanar unit cells 1 of each set 9 are arranged so that adjacent cells have different polarities. An effective electrode reaction area can then be increased per stage of laminate without causing the deterioration of mechanical strength and so output density is increased and anode and cathode terminals can be taken out from the same direction, whereby the productivity and serviceability of the fuel cell are remarkably enhanced.
