摘要： 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.

摘要： 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.

摘要： A method is provided to enhance efficiency of carbon felts in a flow battery. The carbon felts are directly immersed in a mixed acid solution. The carbon felts with the solution are heated at a low temperature and processed through sonication. On surface defects of the carbon felts, —OH and C═O functional groups are efficiently generated. The functional groups catalyze the redox reaction of vanadium ions. More active positions are obtained on the carbon felts through the activation treatment. Both of valence exchange and redox velocity of the vanadium ions are enhanced. Thus, the present invention has simple and fast processes with easily regulated experimental parameters for good modification without high temperature treatment but low cost.

摘要： A method is provided to fabricate electrode used in super-thin flow-battery. A semi-finished cured film is prepared though colloid-mixing, impregnating, and baking. The film is pressed with different materials for fabricating various types of polar plate according to applications. Thus, a thin electrode is fabricated to contain a supporting member with thickness controllable. The electrode obtains excellent resistance to the permeation of vanadium ions; vertical-penetration volume resistance is controlled by adjusting the blending ratio of carbonaceous matter; and the demand of conductivity is met. Besides, the film is prepared to obtain a bipolar plate, a copper-containing current-collecting end plate, or other electrode material like carbon felt, carbon paper, etc. to be combined into an integrated electrode mold. Consequently, different products are obtained with different materials, where the fabrication is simple without using a high-temperature carbonization device and the component cost of flow battery is effectively reduced.

摘要： 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.

摘要： A method is provided for fabricating a catalyst carrier. At first, aluminum hydroxide is used for forming an alumina powder. The alumina powder is mixed with carbon nanotubes and a complex additive to be shaped into a cake. The cake is kneaded into a noodle-like shape to be hot-dried. Then, calcination is processed in a furnace under 1200 celsius degrees (° C.) with air passed through. The crystal structure remains without phase change. A catalyst carrier of α-alumina having nano-scaled pores is formed. The catalyst carrier is a powdery material made into different three-dimensional forms. The catalyst carrier thus fabricated is suitable for generating hydrogen through methane reformation. The catalyst carrier has a methane conversion greater than 99 percents. The catalyst carrier will not be crumbled under 800° C. for 4000 hours without carbon deposit.

摘要： A method is provided for fabricating a carrier catalyst. The carrier catalyst uses an annular carrier of α-alumina (α—Al2O3). The annular carrier of α—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 α—Al2O3. Thus, an annular-carrier catalyst of Pt/CBO2/α—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.
