Abstract
A fullerene-based proton conductor including a proton conductive functional group connected to the fullerene by an at least partially fluorinated spacer molecule. Also, a polymer including at least two of the proton conductors that are connected by a linking molecule. Further, an electrochemical device employing the polymer as a proton exchange membrane, whereby the device is able to achieve a self-humidifying characteristic.
Claims20
An electrochemical device comprising:
- a first electrode,
- a second electrode;
- and
- a polymer disposed between the first electrode and the second electrode allowing one or more protons to be conducted between the first and second electrodes, said polymer comprises a plurality of proton conductors, each comprising a fullerene molecule, a spacer molecule attached to said fullerene molecule wherein said spacer molecule comprising an at least partially fluorinated molecule, a proton conductive functional group attached to said spacer molecule, and at least one linking molecule connected between at least two of said proton conductors.
