摘要： PURPOSE:To obtain the solid electrolyte fuel cell, in which distribution of the gas to each generating cell is evened so as to improve the power generating efficiency. CONSTITUTION:In a collector 1' (separator 3'), manifold grooves 11A, 1B are respectively formed with a slope from a starting point in the gas hole 5A side as an inlet or the gas hole 5B side as an outlet to the end in the gas distribution groove 7B side, which is positioned most far from the starting point. This slope is formed so that the depth at the starting point is deepest and that the depth of the end of both the sides are shallowest. Flow quantity of the gas flowing in each gas distribution groove 7 can be evened by providing a slope of the depth in the manifold groove 11 so that the depth of the manifold groove 11 is formed deeper as it comes close to the gas hole 5 and that the depth thereof is formed shallower as it comes far from the gas hole 5. Distribution and supply of the gas to the power generating cells can be thereby evened, and as a result, homogeneous chemical reaction is generated so as to improve the power generating characteristic, and the excellent solid electrolyte fuel cell can be obtained.

摘要： PURPOSE:To provide a solid electrolyte type fuel cell whose sealing property is improved. CONSTITUTION:A seal material 8 is fused together between a collecting plate (or separator) 3' and a cell 2 for power generation, and a refractory wool material 12 is provided outside this seal material 8. When it reaches a high temperature of 1000 deg.C at power generation, the viscosity of a glass seal material 8 drops, and it flows out, and fuses together with the refractory wool material 12. As a result, firm coupling manifests itself between the seal material 8 and the refractory wool material 12, and favorable seal property can be gotten. Moreover, for the seal material 8, a material of low fusing point, which was difficult of application hitherto, can be selected by coupling with the refractory wool material 12, and the degree of fusion can be strengthened.

摘要： PROBLEM TO BE SOLVED: To provide a method capable of efficiently and simply separating and recovering various kinds of metals from the incineration flying ashes generated when wastes, such as shredder dust, are incinerated or from the molten flying ashes generated when the incineration flying ashes are further melted by a plasma or the like. SOLUTION: After the metals are extracted from the flying ashes, the metals are deposited on an electrode by electrolysis. At this time, the electrolysis is effected in individual stages by stepwise or gradually changing cathode potential in a negative direction. As the result, more than one kinds of the metals are classified and deposited. The fresh flying ashes are preferably subjected to the extraction and classification and deposition of more than one kinds of the metals by the method described above by using the used electrolytic bath as it is after ending the stages from the first metal classification and deposition stage to the final metal classification and deposition stage.

摘要： PURPOSE: To facilitate the inserting work of a sheet, to drastically shorten the inserting time of the sheet into a slit by inserting the ceramic-made sheet into the slit between mold rolls, and to further shorten the working time particularlly by using a green sheet as the sheet because the hardening time is unnecessary. CONSTITUTION: At the time of driving a magnetic flux generating device, an alternating magnetic flux is generated so as to pass between the end parts of the mold rolls 1, 2 and in molten metal between both mold rolls 1, 2. Under this state, a strip is continuously produced from the nearest part between both mold rolls 1, 2 by supplying the molten metal between both mold rolls 1, 2 and rotating in the mutually reverse directions inserting both mold rolls 1, 2. In side surface covers 6 fitted to the side end surfaces of the mold rolls 1, 2, the slits 8 are formed, and in each slit 8, the ceramic-made green sheet 9 is inserted.

摘要： PURPOSE:To provide a solid electrolyte fuel cell of low electric resistance by using a heat resistant metal formed with an inorganic conductive film by a detonation flame spraying method or electron beam method as a separator and collector plate. CONSTITUTION:As a separator 3 and collector plates 4, 5 for a fuel cell, a conductive fine film of LaSrMnO3, LaCrO3, etc., is formed by a detonation flame spraying or electron beam method in a heat resistant metal surface of stainless steel SUS310S or the like, and generation of non-conductive oxidized film in the heat resistant metal surface is prevented to give good conductivity. Thus relating to 1MOMEGAR.cm or more specific resistance in the case of not performing film forming, the specific resistance obtains 0.1OMEGAcm or less, to obtain a material excellent in oxidation resistance at a high temperature (1000 deg.C) further with high electric conductivity shown. Accordingly, by using these materials, a solid electrolyte fuel cell of low electric resistance can be manufactured.
