High performance microbial fuel cells (MFCs) require effective mech. and elec. interaction between electrode surfaces and attached microbial biofilms. Three-dimensional porous electrodes with large-surface area offer an attractive means of achieving this objective. Here we report a novel porous electrode in which a conductive carbon nanotube (CNT) coating is applied to a com. textile. The CNT-textile composite was evaluated as an anode in a MFC. The macroporous structure of textile allowed growth of biofilm inside the anode, increasing the active surface area for electron transfer. The CNT-textile composite outperformed a normal carbon cloth electrode, and appears promising for MFC applications.

Abstract
High performance microbial fuel cells (MFCs) require effective mech. and elec. interaction between electrode surfaces and attached microbial biofilms. Three-dimensional porous electrodes with large-surface area offer an attractive means of achieving this objective. Here we report a novel porous electrode in which a conductive carbon nanotube (CNT) coating is applied to a com. textile. The CNT-textile composite was evaluated as an anode in a MFC. The macroporous structure of textile allowed growth of biofilm inside the anode, increasing the active surface area for electron transfer. The CNT-textile composite outperformed a normal carbon cloth electrode, and appears promising for MFC applications.
