“…This is probably due to the presence of metals and acetate in the MFC media solution that strongly adsorb on Pt. Pt is, indeed, well known to be very sensitive to even trace amounts of metals [25]. This is confirmed by the measurement of the capacitive current in both solutions.…”

Application of iron-based cathode catalysts in a microbial fuel cellBirry, L.; Mehta, P.; Jaouen, F.; Dodelet, J.-P.; Guiot, S.R.; Tartakovsky, B.Electrochimica Acta 56 (2011) [1505][1506][1507][1508][1509][1510][1511] (FePc). These materials were subsequently pyrolyzed at a high temperature. The ORR activity of all Fe-based catalysts was measured at pH 7 with a rotating disk electrode (RDE) and their performance for electricity production was then verified in a continuous flow MFC. Catalysts prepared with FeAc and pyrolyzed in NH 3 showed poor activity in RDE tests as well as a poor performance in a MFC. The ORR activity and fuel cell performance for catalysts prepared with ClFeTMPP and FePc and pyrolyzed in Ar were significantly higher and comparable for both precursors. The iron loading was optimized for FePc-based catalysts. With a constant catalyst load of 2 mg cm −2 in a MFC, the highest power output (550-590 mW/m 2 ) was observed when the Fe content was 0.5-0.8 wt%, corresponding to only 0.01-016 mg Fe/cm 2 . A similar power output was observed using a Pt-based carbon cloth cathode containing 0.5 mg Pt/cm 2 . Long-term stability of the Fe-based cathode (0.5 wt% Fe) was confirmed over 20 days of MFC testing.Crown

“…24 Furthermore, owing to its sensitivity to poisoning, the performance of a Pt based cathode may be substantially diminished in the presence of a variety of chemicals found in wastewater. 25 Recently, a variety of non-precious metal catalysts have been used for MFC applications.26 ORR catalysts are generally used for oxygen cathodes to reduce the overpotential and obtain more energy, which are usually based on metals, carbon, conductive polymers and microbes. 27 Carol Santoro et al 28 have developed new iron-based platinum group metal-free catalysts based on low cost organic precursors named niclosamide and ricobendazole for the ORR.…”

For the improvement of microbial fuel cell (MFC) performance in real wastewater it is necessary to implement catalysts on the cathode. Potential electrochemical catalysts for the MFC have to be widely available and should be low cost materials. Graphite, MnO 2 and MoS 2 fulfill the requirements and were evaluated in this work. These materials were prepared by dispersion of MnO 2 and/or MoS 2 and graphite in a solution of celluloid using butanone as solvent. Four MFCs with an active area of 225 cm 2 were connected in series with the wastewater supply. Their individual maximum output power densities were evaluated in relation to time. The results showed that MFC without catalyst reached a power density of only 40 mW/m 2 , while the best performance of MFC with graphite plus MnO 2 coating (10:1) was higher than 100 mW/m 2 . Comparing with graphite plus MnO 2 coating, the graphite plus MoS 2 paint shows a lower power density but much higher long-term stability than graphite plus MnO 2 coating. The scaling up of MFC with catalyst on the cathode is also studied in this research. Four MFCs with dimension of 980 cm 2 were constructed and connected in series, whose anodes have two sides for enlargement of reaction surface area. Rising demand for energy and fossil fuel resources being finite, the search for new alternative sustainable energy solutions have increased tremendously.1 Hydraulic, wind and solar radiation are clean energy resources as alternatives to fossil resources to produce electricity. However, these energy sources are limited by climate and geographical factors. Comparing with the energy sources that are mentioned above, biomass is one of the important renewable carbon sources and has been recognized as a promising energy supplier in the future. The increasing demand for biofuels has encouraged researchers and politicians worldwide to find sustainable biofuel production systems in accordance with the regional conditions and needs. 2 A MFC is an innovative method to generate electricity from organic matter using exoelectrogenic bacteria.3 Furthermore MFCs have drawn increasing attention as they can generate renewable energy and purify wastewater simultaneously. 4 The main MFC-components are the electrodes, separated into the anodic-and cathodic-chamber. Electrons and protons are produced on the anode from the oxidation of organic matters using bacteria as biocatalyst. In the cathode chamber, an electron acceptor is reduced with the electrons transferred via an external circuit and the protons diffused through the solution. However, complete treatment of wastewater cannot be accomplished solely with MFCs as current production is rapidly reduced to low levels when the chemical oxygen demand of the organic matter is reduced to ∼100-200 mg/L. 6,7 Scaling up MFCs is challenging based on the need to use inexpensive and non-precious metal materials and to achieve good performance. The use of carbon fiber brushes provides a route to make low-cost anodes, [8][9][10] and several different cathodes have been construc...
