Microbial fuel cell (MFC) technology has the potential to become a major renewable energy resource by degrading organic pollutants in wastewater. The performance of MFC directly depends on the kinetics of the electrode reactions within the fuel cell, with the performance of the electrodes heavily influenced by the materials they are made from. A wide range of materials have been tested to improve the performance of MFCs. In the past decade, carbon-based nanomaterials have emerged as promising materials for both anode and cathode construction. Composite materials have also shown to have the potential to become materials of choice for electrode manufacture. Various transition metal oxides have been investigated as alternatives to conventional expensive metals like platinum for oxygen reduction reaction. In this review, different carbon-based nanomaterials and composite materials are discussed for their potential use as MFC electrodes.

“…Power density of FePc/KB was higher than FePc/vulcan-XC and also slightly higher than Pt 23 . Power density obtained for FePc/MWCNT was higher than FePc/KB due to four electron pathway 12 . This also shows that MWCNT is a good supporting material compared to KB.…”

“…Several studies have used oxygen as an effective electron acceptor 11 . However, oxygen reduction reaction (ORR) requires an efficient cathode catalyst for overcoming the high overpotential of electrode 12 . Despite the possibility of using Pt as a cathode catalyst, it is impractical to scaleup the reactor.…”

This work deals with the performance of a microbial fuel cell, focusing on the electrocatalytic activity of selected cathodes constructed by coating nanocomposites over graphite felt under neutral pH in a doublechamber configuration using paper-recycled waste water as a typical electrolyte. Among all cathodes, iron phthalocyanine (FePc) combined multiwalled carbon nanotubes (MWCNT) shows the highest power density (9.34 W/m 2 ) compared to other two catalysts, FePc/Ketjan black (4.68 W/m 2 ) and MWCNT (2.9 W/m 2 ) under similar conditions of using a reference platinum/carbon (Pt/C) loading of 0.5 mg/cm 2 . The morphology of these catalyst coated electrodes was characterized by scanning electron microscopy. Their electrocatalytic activities were examined using cyclic voltammetry. This work provides an appropriate alternative for cathode catalysts in treatment as well as in electricity production as demonstrated by the high power density of the above catalysts compared to that using precious Pt metal catalyst in microbial fuel cells.
