Self-sustainability of Benthic microbial fuel cell makes it a future possibility to solve the problem of the power source for low power devices. New 3D electrode; Resorcinol-Urea-Formaldehyde Carbon xerogel was synthesized on steel wool by using the one-pot method and tested in lab scale BMFC. Xerogel was prepared by heating polymerized aerogel at 900 °C in presence of Nitrogen. Magnetite was also added in aerogel to produce magnetite doped xerogel electrode. These composites were characterized by Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Chronocoulomerty (CC), Cyclic voltammetry (CV), and Electrochemical impedance spectrometry (EIS). Resorcinol xerogel provides good biocompatibility, hydrophilicity, porosity, and efficient surface for the electrode. 3D composite electrode enhanced the performance of BMFC. 3D Magnetite doped xerogel shows utmost performance with maximum power density of 895 mW m⁻³ in comparison of 14 mW m⁻³ produced by carbon felt. 3D Resorcinol xerogel proves its significance by enhancing power generation in the lab-scale BMFC reactor.
