Embodiments in accordance with the present invention encompass a variety of polymers derived from polycyclic olefin monomers, such as hydrocarbon functionalized norbornenes. The polymers so formed function as ionomers and are suitable as anion exchange membrane for fabricating a variety of electrochemical devices, among others. More specifically, the ionomeric polymers used herein are derived from a variety of quaternized amino functionalized norbornene monomers and are lightly crosslinked (less than ten mol %). The membranes made therefrom exhibit very high ionic conductivity of up to 198 mS/cm at 80° C. This invention also relates to using an anion conducting solid polymer electrolyte as the ion conducting medium between the two electrodes and the ion conducting medium within the electrodes acting as the ionic conduit between electroactive material and electrolyte. The electrochemical devices made in accordance of this invention are useful as fuel cells, gas separators, and the like.

Polycyloolefinic polymers and anion exchange membranes derived therefrom

The invention relates to an anion-exchange membrane (AEM) having a multiblock copolymer including a hydrophilic norbornene-based monomer and a hydrophobic alkene-based or norbornene-based monomer. The hydrophilic norbornene-based monomers include one or more cationic head groups such as a quaternary ammonium ion, which can optionally be crosslinked with a crosslinking agent to increase the structural stability of the polymer. These AEMs can be employed in electrochemical devices such as fuel cells.
