Patent number: 11897172Abstract: A polar plate is fabricated. The polar plate is flexible and made of a plastic graphite composite. No matter a supporting member is used for calendering or not, a thin polar plate with controllable thickness is fabricated. The polar plate is excellent in blocking the through-transmission of vanadium ions and the limit of blending ratio of conductive carbon is broken through. The longitudinal through-transmission volume resistivity (proportional resistance to thickness) is greatly improved by adjusting the blending ratio of conductive carbon for meeting the demand of conductivity. In the mean time, the present invention strengthens the rigidity required for the thin polar plate while providing large-area polar plate fabrication for industrial use and convenience and provides a cooling and pressing method for patterning a composite polar plate. An integrated mold is thus obtained to replace the conventional polar plate which needs to be processed and prepared with runner.Type: GrantFiled: September 2, 2021Date of Patent: February 13, 2024Assignee: Institute of Nuclear Energy Research, Atomic Energy Council, Executive Yuan, R.O.C.Inventors: Hung-Hsien Ku, Ning-Yih Hsu, Han-Jou Lin, Tai-Feng Hung, Qiao-Ya Chen

Patent number: 11327117Abstract: An apparatus is provided for measuring the power of electrolytes at different positions of a flow battery by switching six-way valves without reconnecting channels. With the measurements at the positions, weighting is processed to obtain power corresponding to charging statuses for determining accurate power. The charging and discharging of voltage and current of the battery are controlled for constant operations with high efficiency. Consequently, the efficiency of power conversion is improved; energy consumption is reduced; and the battery is always run within a safe power-range for avoiding accidents or damages to the battery. In addition, the present invention is further applicable to a device monitoring the features of a battery unit. The six-way valves online monitor the power at center positions by switching. The values measured at different positions are aimed at the abnormality of the battery unit for processing adjustment or offline replacement to maintain best operation performance.Type: GrantFiled: September 8, 2020Date of Patent: May 10, 2022Assignee: Institute of Nuclear Energy Research, Atomic Energy Council, Executive Yuan, R.O.C.Inventors: Hung-Hsien Ku, Ning-Yih Hsu, Chin-Lung Hsieh, Yi-Hsin Hu, Qiao-Ya Chen

Patent number: 11251452Abstract: A method is provided for restoring an electrolyte of vanadium (V) redox flow battery (VRFB). Electrolyte data of an original system are analyzed in advance. A reusable positive electrode is further equipped with a V electrolyte. A reductant for a stack of VRFB is used in coordination as an electrolysis device. After a long-term reaction with a VRFB having a high valence (greater than 3.5), an electrolyte at the positive electrode is directed out to a negative electrode of the electrolysis device; and, then, electrolysis is processed after accurate calculation. In the end, the internal fluid balancing method of the original system is combined. Thus, a harmless and quick valence restoration is processed for the electrolyte of the original system, which is a final resort for the restoration of V electrolyte.Type: GrantFiled: January 8, 2020Date of Patent: February 15, 2022Assignee: Institute of Nuclear Energy Research, Atomic Energy Council, Executive Yuan, R.O.C.Inventors: Yu-De Zhuang, Chien-Hong Lin, Yi-Hsin Hu, Han-Wen Chou, Hwa-Jou Wei, Ning-Yih Hsu

Patent number: 10826101Abstract: A flow battery apparatus is provided with shunted currents repressed. The apparatus has a positive electrode device, a negative electrode device and a plurality of gas-gap devices. Gas-gap devices are separately set between branching channels and inlet and outlet manifolds of positive and negative electrodes. Each of the branching channels separately has an inserting tube to be inserted into one of the gas-gap devices. The diameter of the inserted vessel of gas-gap devices is bigger than the diameter of the inserting tube connected to a corresponding one of the branching channels. Thus, working liquids transferred to the positive and negative electrodes are segregated with coordination of the gas-gap devices. Only air spaces and discrete liquid drops are left between separated parts of the working liquids. Thus, shunted currents are repressed by preventing conductive paths from being formed between the positive and negative electrodes.Type: GrantFiled: January 18, 2019Date of Patent: November 3, 2020Assignee: Institute of Nuclear Energy Research, Atomic Energy Council, Executive Yuan, R.O.C.Inventors: Hwei-Liang Chang, Ning-Yih Hsu, Yao-Sheng Hsu, Zone-Sure Chang

Publication number: 20160375425Abstract: A method is provided for fabricating a carrier catalyst. The carrier catalyst uses an annular carrier of ?-alumina (?—Al2O3). The annular carrier of ?—Al2O3 has stable activity. By analyzing characteristics and methane conversion rates of catalysts with different compositions, a solution for solving carbon deposition is found. Cerium oxide (CeO2) is used as an accelerator and platinum (Pt) nano-particles are used as catalyzer. The above components are impregnated and coated on the annular carrier of ?—Al2O3. Thus, an annular-carrier catalyst of Pt/CBO2/?—Al2O3 is formed. Therein, the present invention uses carbon nanotubes before calcining the annular carrier catalyst. Consequently, its microstructure is modified to obtain a surface area of 130 square meters per gram and an average pore size of 12.585 angstroms. Preferably, 0.5 percents of platinum nano-particles are to be added into the carrier catalyst to achieve a 79% methane conversion rate even after 25 hours of reformation reaction.Type: ApplicationFiled: March 25, 2016Publication date: December 29, 2016Inventors: Yi-Si Chou, Men-Han Huang, Ning-Yih Hsu, Ruey-Yi Lee, Kin-Fu Lin
