Abstract
Proton conductive fullerene materials are incorporated in minor amounts into various polymeric materials to enhance the low relative humidity proton conductivity properties of the polymeric material. The resulting proton conductors may be used as polymer electrolyte membranes in fuel cells operative over a wide range of relative humidity conditions and over a wide range of temperatures from below room temperature to above the boiling point of water.
