摘要: Disclosed are a micropore-filled amphoteric membrane for low vanadium ion permeability, a method of manufacturing the same, and a vanadium redox flow battery including the amphoteric membrane. The micropore-filled amphoteric membrane for low vanadium ion permeability minimizes crossover of vanadium ions, which occurs between a catholyte and an anolyte in a redox flow battery, and has low membrane resistance and thus has remarkably improved performance as compared to commercially available ion-exchange membranes such as Nafion, and accordingly, can be effectively used in the manufacture of a redox flow battery. In addition, the micropore-filled amphoteric membrane is continuously manufactured through a roll-to-roll process, and thus the manufacturing process is simple and manufacturing costs can be greatly reduced.

摘要: A method of producing an electrochemical fuel cell device with one or more electrodes containing one or more electrocatalysts. The method involves the steps of, first, affixing a semi-permeable membrane with inhomogeneous conduction pathways to a conducting surface of a first electrode in a predetermined configuration to form a first electrode assembly. This assembly is then immersed in an electrolyte containing at least one electrochemical precursor with for forming an active electrocatalyst on the conducting surface of the first electrode when a potential is applied to the first electrode. The same process can occur with a second electrode assembly which can be joined to the first electrode assembly before or after the electrocatalyst deposition.

摘要: Multi-acid polymers are produced having the formula R—SO2—NH—(SO3−H+)n or R—SO2—NH—(PO3−H2+)n and made from a polymer precursor in sulfonyl fluoride form or sulfonyl chloride form The R is one or more units of the polymer precursor without sulfonyl fluoride or sulfonyl chloride, n is one or more, and the multi-acid polymer has two or more proton conducting groups. A method of making the multi-acid polymers includes reacting an amino acid having multiple sulfonic acids or phosphonic acids with a polymer precursor in sulfonyl fluoride form or sulfonyl chloride form in a mild base condition to produce the multi-acid polymer having two or more proton conducting groups.
