Ascorbic Acid Fuel Cells Using Nano Carbon and Conducting Polymer Composites for Anode and Paper for Separator

Performances of direct ascorbic acid fuel cells using anodes of nano carbons (SWCNT, graphene, C-60) and their composites with conducting polymers were studied. The output power using polyaniline@SWCNT composite was 8.7 mW cm(-2) for Nafion separator and Pt cathode. Cells using PEDOT*PSS@SWCNT composite and filter paper for separator exhibited power >2 mW cm(-2). The facts are explained by the idea that PEDOT*PSS plays the role of cation exchange membrane.
