Embodiments in accordance with the present invention encompass a variety of polymers derived from polycyclic olefin monomers, such as hydrocarbon functionalized norbomenes. 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. 2.
