Freestanding sulfonated graphene oxide paper: a new polymer electrolyte for polymer electrolyte fuel cells.
Sulfonated graphene oxide paper was fabricated by vacuum filtration of a colloidal solution of sulfonated graphite oxide. Layer by layer assembly of graphene oxide nano sheets interconnects the conduction paths and therefore sulfonated graphene oxide exhibits good proton conductivity and fuel cell performance.
