摘要： PURPOSE:To lessen the electric contact resistance between a solid electrolytic membrane and an electrode membrane and heighten the physical strength of the electrode membrane. CONSTITUTION:A cut part corresponding to the thickness of an oxygen-side electrode or a fuel-side electrode is formed in both sides of an electrolytic ceramic body 1 and a fine powder of the electrode 2 in the oxygen side is stuck to one cut part like a film and a fine powder of the electrode 2 in the fuel side is stuck to the other cut part like a film by spraying. Then, with that state, the resulting body is heated to 1500 deg.C at 5-100 deg.C/hour by an electric furnace, etc., and held for about 1-10 hours to be sintered and cooled gradually at about 100-200 deg.C/hour.

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 obtain a flat platelike baked material having high flatness by providing a placing table in a furnace body, a table elevation mechanism, and a load weight plate in which a material to be baked on the table is pressed to its lower surface when the table rises. CONSTITUTION:A green body 36 is placed on a table 28, and the table 28 is lifted to a predetermined position. A temperature in a baking chamber 18 is gradually raised in this state, and the body is temporarily baked. After the temporarily baking and contracting are finished to certain degree, the table 28 is lifted while raising the temperature in the chamber 18. Then, a load weight plate 32 is superposed on the material to be baked, and a frame 30 is raised. Since the plate 32 is held on the frame 30 and brought into close contact with the entire surface of the material on the table 28 lifted from below in a horizontal state, a uniform pressing force can be effectively applied to the material, no warpage occurs, and a ceramic flat plate of high quality without baking irregularity can be baked.

摘要： PURPOSE:To increase the number of unit cell laminates per unit volume and to improve the volume output density by laminating numerous plate-form unit cells through porous bodies for gas passage, making the opposite surfaces of neighboring unit cells in the same sort of electrode membranes, and using the porous bodies for gas passage for fuel flow passages and air flow passages alternatively. CONSTITUTION:A unit cell 1 consists of a plate-form solid electrolyte 3, and an oxygen electrode membrane 2 and a fuel electrode membrane 4 laminated on both sides of the solid electrolyte 3 respectively, And numerous unit cells 1 are laminated through porous bodies 7a and 7b for gas passages, and porous plates 5 for connector are provided to the electrode surfaces 2 and 4 of each unit cell 1. And the opposite surfaces of neighboring two cells, the upper side of the uppermost unit cell 1, and the lower side of the lowermost cell 1, are made in the same sort of electrode. Furthermore, the porous bodies for gas passage 7a and 7b are used for fuel flow passage and air flow passage alternatively. As a result, gas separators are not necessary to prepare, and thereby the number of laminate members is reduced, and the laminate members can be made thinner. Consequently, the laminating number of unit cells per unit volume can be increased, and the volume output density can be improved.

摘要： PURPOSE:To enhance the output per unit volume of a solid electrolyte fuel cell in which a number of cells are stacked by providing gas passages among the cells, and providing an electron passage within the projected area of a cell power generating portion which is formed by a gas separator. CONSTITUTION:The projected area of a cell power generating portion formed by a gas separator is an area formed by direct projection of a cell electrode face when cells are stacked, excepting the frame body portion of the separator. The separator 1 comprises a stack portion 3 forming the outer shape thereof, a gas inflow frame 4, a separator portion 2 for separating a fuel passage from an air passage, an electron passage 6 passing through the separator portion 2, and a current collector supporting portion 5 consisting of protruding portions located between the separator portion 2 and the electron passage 6. Electron- conductive electrode material or ceramics of LaCrO3, etc., is used for the passage 6 and a solid structure is used in the separator 1 so that MgAl2O4 and MgO are mixed together and that gas is not allowed to pass therethrough.

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.
