摘要： A method for bonding together two or more acid-doped polybenzimidazole films is provided. The method includes, in the following order: placing a first acid-doped polybenzimidazole film on a first substrate to form a first film/substrate assembly and placing a second acid-doped polybenzimidazole film on a second substrate to form a second film/substrate assembly; heating the first and second film/substrate assemblies to a temperature sufficient to soften the first and second acid-doped polybenzimidazole films; positioning the second film/substrate assembly atop the first film/substrate assembly, such that polybenzimidazole polymer chains of the first acid-doped polybenzimidazole film interact with polybenzimidazole polymer chains of the second acid-doped polybenzimidazole film; and re-hydrolyzing the first and second acid-doped polybenzimidazole films, such that the polybenzimidazole polymer chains of the first and second acid-doped polybenzimidazole films are therefore reformed and interlocked with each other to bond together the first and second acid-doped polybenzimidazole films.

摘要： A flow battery includes an electrochemical cell that has a first electrode, a second electrode spaced apart from the first electrode, and a separator layer arranged between the first electrode and the second electrode. The separator layer is formed of a polymer that has a polymer backbone with cyclic groups that are free of unsaturated nitrogen and one or more polar groups bonded between the cyclic groups.

摘要： Multi-acid polymers are produced having the formula R—SO2—NH—R′—(SO3H)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, R′ is the portion of the amino sulfonic acid without the SO3H and NH, 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 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.
