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.

The small square oxygen electrode film 2 and the small fuel electrode film 4 with the same size are arranged and laminated at symmetrical positions respectively on both faces of the solid electrode 3, and they are regularly arranged at a fine interval into a tile shape. Unit cell groups are connected in parallel and serially via current collecting porous plates 5. The current value flowing in the unit cell groups in made constant, the occurrence of thermal stress is suppressed, and the peeling of electrode films and the breakage of unit cells can be prevented. Nonconducting YSZ 7 is filled between the small electrode films, and the mechanical strength of unit cells is improved.

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 increase the number of unit cell laminats per unit volume and to improve the volume output density by laminating numerous unit cells through spacers using the spaces between unit cells for fuel flow passages and air flow passages alternatively. CONSTITUTION:A unit cell 1 is composed of a cell member which consists of a plate-form solid electrolyte 3, and a fuel electrode membrane 4 and an oxygen electrode membrane 2 laminated on both sides of the solid electrolyte respectively; and ceramics tubes 6 penetrating the cell member and projecting a specific length to the both electrodes 2 and 4. The ceramics tube 6 furnishes a heatproof metal wire 7 at the center, and has a role to connect the unit cells in series electrically. The unit cells 1 furnishing ceramics tubes for connecting cells in such a way are laminated numerously through spacers 11 making the opposite surfaces in the same sort of electrode membranes, and the spaces between the unit cells are used for exclusive flow passages of the fuel and the air alternatively. As a reslt, it is unnecessary to prepare gas separators and the like. Consequently, the number of laminating unit cells per unit volume can be increased, and the volume output density can be improved.

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 manufacture an electric collector body with which electricity generation of a solid electrolyte type fuel battery is improved by using a metal plate, on which an electron-transmissive and oxidation-resistant ceramic is evaporated, as an electric collector body for a solid electrolyte-type fuel battery. CONSTITUTION:After a substrate 5 is heated to, for example at the highest 1000 deg.C in a vacuum container 1 having crucibles 2a and 2b filled with La powder and Cr powder, respectively, as evaporation materials and the pressure of the vacuum container 1 is lowered to 1X10 Torr, oxygen gas in at highest 1X10 Torr is led to the container through a controlling and a stopping valves, and then electricity with optimum accelerating voltage and ionization current for controlling the quality of a film is applied to an ion gun, and when they become stable, reactive evaporation is started. The lanthanum ion beam radiated from the crucible 2a and the chromium ion beam radiated from the crucible 2b are evaporated on the substrate 5 and formed into a film while becoming a LaCrO3-based ceramic in the oxidizing atmosphere due to the oxygen supplied from an oxygen supplying tube 9.

摘要： PURPOSE:To reduce the starting time and the stopping time of a cell by reducing the resistance of an electrolyte and the electrode reaction to increase the reaction speed, and lowering the cell operative temperature. CONSTITUTION:As a solid electrolyte, a CeO2 system ceramics with a high oxygen ion conductivity is used, and by making the solid electrode in a thin membrane (less than 20mum), forming a film of a fuel electrode material on the surface of an inorganic porous base substance to increase the surface area of the fuel electrode so as to increase the contact surface with a fuel gas, and using a porous oxygen electrode to increase the contact surface with an oxidizer gas, the resistance of the solid electrolyte and the resistance of the electrode reactions can be reduced to prevent the reduction of the reaction speed. As a result, even when the cell is operated at a low temperature (less than 800 deg.C, for example), the energy efficiency and the output intensity same as or higher than the case on a high temperature operation at 1000 deg.C can be obtained. Consequently, the starting and a stopping of the cell can be made in a shorter time.
