    摘要： An ion conducting polymeric composition mixture comprises a copolymer of styrene and vinylbenzyl-Rs. Rs is selected from the group consisting of imidazoliums and pyridiniums. The composition contains 10%-90% by weight of vinylbenzyl-Rs. The composition can further comprise a polyolefin comprising substituted polyolefins, a polymer comprising cyclic amine groups, a polymer comprising at least one of a phenylene group and a phenyl group, a polyamide, and/or the reaction product of a constituent having two carbon-carbon double bonds. The composition can be in the form of a membrane. In a preferred embodiment, the membrane is a Helper Membrane that increases the faradaic efficiency of an electrochemical cell into which the membrane is incorporated, and also allows product formation at lower voltages than in cells without the Helper Membrane.

    摘要： Water electrolyzers comprises an anode comprising a quantity of anode catalyst, a cathode comprising a quantity of cathode catalyst with an inlet for introducing a cathode reactant thereto, an anion-conducting polymer electrolyte membrane interposed between said anode and said cathode, and a source of electrical energy that applies a voltage between the anode and cathode. At least one of said anode catalyst or said cathode catalyst comprises a metal or metal alloy having a surface area of at least 12 m2/gm. Water electrolyzers preferably employ base metal catalysts and an anion-conducting polymeric membrane with a resistance below 0.3 ohm-cm2 and a base metal catalyst with a surface area of at least 12 m2/mg.

    摘要： A battery comprises an ion-conducting polymeric composition comprising a copolymer of styrene and vinylbenzyl-Rs, where Rs is a positively charged cyclic amine group. The ion-conducting polymeric composition can be in the form of a membrane. The ion-conducting polymeric composition can comprise a terpolymer of styrene, vinylbenzyl-Rs and vinylbenzyl-Rx, in which Rs is a positively charged cyclic amine group, Rx is at least one constituent selected from the group consisting of Cl, OH, and a reaction product between an OH or a Cl and a species other than a cyclic amine or a simple amine, the total weight of the vinylbenzyl-Rx groups is greater than 1% of the total weight of the membrane, and the total weight of the vinylbenzyl-Rs groups is 15% or more of the total weight of the membrane.
