摘要： PROBLEM TO BE SOLVED: To reduce thermal stress which occurs at the time of heating, firing and cooling, to prevent the formation of strain, cracks or the like and to realize long life by separating a sagger into a frame body part and a bottom plate part which protrudes from the periphery of the frame body part and is made of a ceramics having high thermal conductivity. SOLUTION: Saggers, each being composed of a frame body 1 and a bottom plate 2 are piled up to the required number of steps and matters to be fired are put on each bottom plate 2. Thereafter, the saggers are introduced into a continuous-of batch-type furnace and the matters to be fired are fired. These saggers are each made a separated structure that the frame body 1 is separated from the bottom plate 2. Further, the bottom plate 2 extrudes by a prescribed width α, e.g. about 5 to 50 mm, from the periphery of the frame body 1, and projecting parts, notched parts or the like which fit with the lower part of the frame body 1 are optionally provided. Further, it is preferable that the bottom plate 2 is formed using a highly thermal-conductive ceramic such as Al2O3 and, if necessary, the upper face or the lower face of the bottom plate 2 is laminated with a metal plate, thereby the time for firing the matter to be fired can be shortened and thermal stress is further reduced.

摘要： PURPOSE:To lessen the internal resistance and provide excellent voltage efficiency by providing continuously or intermittently a gathering of electroconductive fibers whose length exposed to one side of a resin plate is below a specific value. CONSTITUTION:A double-electrode partitioning plate 10 consists of a resin plate 2 and gathering 1 of electroconductive fibers, wherein the latter 1 penetrates the former 2 in such a way that one unitary cycle of penetrating from one side of the plate 2 to the other side and returning is repeated continuously or intermittently. The length of one unit of fiber gathering exposed to one side is made below 20mm, or preferably 15mm. Exceeding 20mm raises the internal resistance of the battery because of voltage drop due to electric resistance of the fiber gathering itself. In this double-electrode partitioning plate 10, the fiber 1 can form good conductive portion, so that suppressing the fiber length within 20mm permits constituting battery with lesser internal resistance.

摘要： PURPOSE:To obtain a strong electrolyte container or battery in which liquid leakage or the like hardly occurs by joining together a multipolar partition plate, a diaphragm and spacers. CONSTITUTION:A multipolar partition plate 1, a diaphragm 5 and chamber frames 2 and 4 are joined together by self-fusion. For example, a hard polyvinyl chloride resin sheet of 0.5mm. thickness containing carbon powder is used as the partition plate 1. Hard polyvinyl chloride resin plates of 2mm. thickness are used as the spacers 2 and 4. In addition, a porous resin film of the polyvinyl chloride system is used as the diaphragm 5. Next, a carbon fiber felt 3 is packed into each of electrode chambers surrounded by the spacers 2 and 4. After that, the partition plate 1, the spacers 2 and 4 and the diaphragm 5 are stuck together by applying to them an adhesive prepared by dissolving polyvinyl chloride resin in a mixture solution composed of cyclohexanone, methyl ethyl keton and tetrahydrofuran, thereby making a cell stack.

摘要： PURPOSE:To test the toughness against breakdown at a high temperature and a high pressure with a miniaturized device, by leading a fluid to a test piece storing part having a heating means and a load part continuously and pressing a piston of the load part by this fluid to apply a load to a test piece. CONSTITUTION:After a test piece 9 is grasped by grasping materials 10 and 14, an aperture part is closed by a cover 25, and the cover 25 is fixed by a nut 27. Electric power is supplied to a heater 26 to heat the inside of a storage chamber 4 and the test piece 9 to a prescribed temperature, and high-pressure gaseous hydrogen is supplied as atmospheric gas from a fluid supply tube 20, thus making the inside of the storage chamber 4 high-temperature and high-pressure. The pressure of gaseous hydrogen acts upon a piston 7 in a load part 3, and this force is measured through a connecting rod 15, the grasping material 14, the test piece 9, the grasping material 10, and a connecting rod 11 by a load cell 12. The piston 7 falls in accordance with the fatigue of the test piece 9, and this fall is measured by a displacement meter 16, thus testing the toughness against breakdown at a high temperature and a high pressure.

摘要： PURPOSE:To obtain a secondary battery device with which a surplus output can be obtained during emergency electric discharge according to necessity by installing a device in which at least one of a positive and negative active material is produced through reaction. CONSTITUTION:A secondary battery device has an anolyte tank 6, a liquid supply pump 13, an anolyte line 14, a catholyte tank 7, a liquid supply pump 12 and a catholyte line 15. In order to produce an electric power of at least the rated charging amount, a halogen acid such as hydrochloric acid contained in a tank 9 is added to a halogen oxide contained in a reactor 8 to produce a halogen. The thus produced halogen is poured into an anolyte line 14 to increase the amount of the positive active material, thereby producing an electric power of at least the rated charging amount. A negative active material liquid contained in a line 20 is passed through a tower 10 packed with iron pieces to prepare a catholyte with high concentration. The thus prepared catholyte is supplied into the negative electrode 3 of a battery 1, thereby producing an electric power of at least the rated charging amount.

摘要： PURPOSE:To enable an active material solution which can be favorably used for a redox-flow battery to be easily prepared by dissolving a raw material containing chromium and iron, such as a chromium ore or chromite, in hydrochloric acid before removing mainly heavy metals contained in the solution by depositing them on the electrode of a cathodic chamber through electrodeposition or adsorption. CONSTITUTION:After a raw material containing chromium and iron is crushed and dissolved into hydrochloric acid, the residue is filtered off from the solution. When a chromium ore or a similar material which does not easily dissolve in hydrochloric acid is used as the raw material, it is preferable that nitric acid be added as necessary in addition to performing heating during the dissolution. The thus prepared hydrochloric acid solution of chromium and iron is then introduced into the cathodic chamber of an electrolyzer so as to remove mainly heavy metals contained in the solution by depositing them on the electrode of the cathodic chamber through electrodeposition or adsorption. Through performing this process, heavy metals and nitrate ions contained in the solution are removed, thereby enabling current efficiency to be greatly increased.
