Electrospun and solution blown three-dimensional carbon fiber nonwovens for application as electrodes in microbial fuel cells

Three-dimensional carbon fiber electrodes prepared by electrospinning and solution blowing are shown to be excellent electrode materials for bioelectrochemical systems such as microbial fuel cells or microbial electrolysis cells. The bioelectrocatalytic anode current density is shown to reach values of up to 30 A m(-2), which represents the highest reported values for electroactive microbial biofilms.
