Abstract
The present invention is directed to proton exchange membranes such as for use in fuel cells. In one embodiment, a polyetherquinoxaline is obtained by reaction between a haloquinoxaline and at least one diol, which forms a repeating unit including an ether linkage. The polyetherquinoxaline is suitable for use in a proton exchange membrane, which can be used in a fuel cell.
