ABSTRACT:
A solid acid including a carbon nanotube (CNT), a spacer group combined with the CNT and an ionically conductive functional group connected to the spacer group. A polymer electrolyte membrane may include the same composition, and may be used in a fuel cell. The polymer electrolyte membrane using the solid acid has excellent ionic conductivity and suppresses the cross-over of methanol. The polymer electrolyte membrane is used as an electrolyte membrane of a fuel cell, for example, a direct methanol fuel cell.
