摘要： PROBLEM TO BE SOLVED: To provide a sodium-sulfur battery, capable of high output operation and stably operating over a long period.
SOLUTION: The sodium-sulfur battery is formed, by arranging a high-resistance layer having preferential permeability to sodium polysulfide higher than that to sulfur, between a solid electrolyte and a current-collecting electrode, and arranging a cylinder-shaped auxiliary conductor, having preferential permeability to sulfur higher than that to sodium polysulfide on its outer periphery. An appropriate flow path of sodium polysulfide is formed, by making the high-resistance layer penetrate in the radial direction of the auxiliary conductor.

摘要： PROBLEM TO BE SOLVED: To prevent photoelastic effect from being generated in a Pockels element, and to stabilize measurement accuracy even receiving a stress due to the vibration and temperature change of installation environment by supporting the Pockels element by a buffer material for fixing, and by bonding other optical parts to a substrate. SOLUTION: A photovoltaic sensor is composed of a polarizer module 5 consisting of a Pockels element 1, a 1/4 wavelength plate 2, a polarizer 3, and a prism 4, and/or an analyzer module 8 consisting of an analyzer 6 and a prism 7. Optical parts other then the Pockels element 1 are bonded to a substrate 9a. Each light I/O terminal comprising collimators 13a, 13b, and 13c and light connection terminals 12a, 12b, and 12c are also bonded to the substrate after an optical axis is adjusted. The Pockels element 1 where an electrode sheet 11 is provided at upper and lower parts is pressed from four directions being vertical to the optical axis by a buffer material 10 for fixing, and also is not brought into contact with other optical parts, thus suppressing stress being applied to the Pockels element 1 by vibration and temperature change.

摘要： PURPOSE:To suppress the scattering loss of carbonate without promoting material corrosion by allowing a reservoir inner part to communicate with anode gas. CONSTITUTION:A part of a reaction gas passage 6 opened on an anode 2 side is exclusively used as a reservoir 10 for carbonate, and the part of the anode in contact with the reservoir 10 is removed along the reaction gas passage so that the carbonate is not directly supplied to the anode 2 from the carbonate reservoir 10, and an electrolytic plate 1 having the same thickness as the anode is charged to form a carbonate supplying passage 11. By allowing the reservoir 10 inner part to communicate with the anode gas, the reservoir 10 inner part is ventilated by the anode gas, and the oxygen entrained in the reservoir at the time of assembling a cell is sent out and never left in the inner part, so that the corrosion of the metal material around the reservoir 10 is never promoted, and the vapor pressure of the molten carbonate is increased, resulting in a reduction in the carbonate quantity scattered through a communicating hole.

摘要： PURPOSE:To prevent gas-cross from occurring even if an electrolyte layer is enlarged in its area by making up each electrolyte layer out of the junction section of a plurality of electrolyte plates with a plurality of electrolyte plates which contain non-organic fibers for carrying molten salt. CONSTITUTION:Adhesive agent is made while non-organic fibers, organic binder and carbonate are being mixed together. A green sheet forming the first layer is composed of 2 rectangular green sheets 1a and 1b which are different in size and are formed in such a way that they are joined together while the aforesaid adhesive agent is applied to the side surfaces of them. And furthermore, 3 more green sheets are prepared in a similar way. These 4 green sheets are alternately pile up in such a way that respective joints are not over-lapped so that a matrix layer 5 is thereby formed. By this constitution, there is no need for worrying about gas-cross through which anode gas 17 is mixed with cathode gas 18 while penetrating the whole of the electrolyte layer through the junction sections C in a fuel battery employing the aforesaid matrix layer 5.

摘要： PURPOSE:To make it possible to safely, easily supplement liquid electrolyte from the outside to the matrix of a unit cell by forming an electrolyte supplement unit with a supplement passage in which a porous body is filled so that an electrolyte is retained and passed, an exfoliated part, and a supplement pipe. CONSTITUTION:An electrolyte supplement unit is formed with a supplement passage 8 in which a porous body 1 is filled in a specified passage so that an electrolyte is retained and passed, an exfoliated part 10 in which catalysts 5a, 5b and a water repellent layer 9 between the supplement passage 8 and a matrix 4 are exfoliated, and a supplement pipe 12 which connects the supplement passage 8 and a storage tank. The gas passage in a part of an electrode to which water repellent treatment is applied is used as the supplement passage of electrolyte. Since the electrode is formed with porous substrate, the electrode can selectively pass only the electrolyte. The electrolyte flows in the direction from the supplement passage to the matrix 4. Liquid electrolyte is safely, easily supplemented from the outside to the matrix 4 of the unit cell.

摘要： PURPOSE:To protect a cell from the abnormal pressure difference by systematizing the automatic stop of fuel and oxidant and the supply of inert gas in a predetermined direction from a pressure vessel with no necessity of using a backup electric source or a computer, when electric power or control signal breaks down. CONSTITUTION:In power failure, for example, solenoid valves 8, 9 are mechanically full closed to stop the feed of fuel and oxidant. Also, solenoid valves 12, 14 are mechanically full closed to let inert gas flow through check valves 13, 15 keeping the pressure balance between inert gas and an anode 1 and a cathode 2 at a predetermined pressure difference. These check valves do not function so far as the pressure at upstream side is not higher than the pressure at downstream side by the pressure loss. By appropriately choosing check valves 13, 15, the holding pressure difference of the anode and cathode against inert gas can be determined. By the arrangement, stable stop of the power generation and retention of the fuel cell becomes possible preventing from its abnormal pressure difference.

摘要： PURPOSE:To make it possible to lengthen the life and to increase the performance of a fuel cell by installing a device and a method by which oxidizing agent supply shortage is temporarily brought during the operation of a fuel cell. CONSTITUTION:Cell output controllers 6 are installed in cell stacks 11, 12,...1N. Flow controllers such as flow regulating valves 7 are installed in oxidizing agent supply lines 5. A controller 8 is arranged between the cell output controllers, the flow regulating valves 7 and a load current detector 3. A specific cell stack 11 of a series stack 1 is temporarily brought in an oxidizing agent shortage state during the operation of the series stack 1 without a decrease in load current of the series stack 1. By this process, the deterioration in cell performance with the passage of time is retarded and cell perforamnce is increased.

摘要： PROBLEM TO BE SOLVED: To produce the digital output signals of a photo-CT(photoelectric current transformer) without using an accurate A-to-D converter and enhance the reliability of a protection relay system. SOLUTION: The angle of polarization by the Faraday effect brought about in a sensor fiber wrapped around a conductor is detected as variation in intensity by photodetectors 120 and 130, and the signal difference obtained from the output of amplifiers (123 and 133) or (124 and 134) with a high or low amplication factor according to the high or low value thereof is digitized in a conversion portions (A/D2) or (A/D3). Thus, the individual conversion portions (A/D2) and (A/D3) do not require an especially large number of bits. In addition, sampling is performed at a frequency 360 or higher than the frequency of the photo-CT system current and any delay arising from transmission is corrected at a digital relay processing portion, so that protection relay processing can be performed at a current with less phase delay. The value of the current of the photo-CT and presence/absence of a sensor trouble are transmitted as transmission data to a digital relay, so that malfunction of the digital relay due to malfunction of the photo-CT is prevented.
