ABSTRACT:
An ionic conductor, such as a proton conductor, a process for production thereof, and an electrochemical device, such as fuel cell, that includes the ionic conductor is provided. The ionic conductor of the present invention is formed from a polymer in which carbon clusters having ion dissociating functional groups are bonded to each other through connecting groups which can also include one or more ion dissociating functional groups. In this regard, the polymer is less water-soluble and more chemically stable than a derivative composed solely of carbon clusters, thus displaying enhanced ionic conduction properties.
