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...

“…Katoda dari bahan karbon aktif terbukti dapat memproduksi energi listrik sama atau lebih besar daripada katoda yang terbuat dengan katalis Platinum (Zhang et al 2009a). Performa dari karbon aktif lebih tahan lama dibandingkan Platinum, dan produksi listrik hampir mendekati katoda jenis baru yang menggunakan perlakuan asam (Zhang et al 2015). Karbon aktif secara khas terbentuk dari material karbon yang mempunyai aktivitas katalitik yang baik, namun konduktivitas listrik yang dihasilkan masih rendah jika dibandingkan dengan karbon berbentuk kain/lembaran.…”

“…Nilai elektrisitas yang dihasilkan rendah searah dengan penurunan COD semakin rendah. Hal ini sesuai penelitian Zhang et al (2015) yang menyebutkan bahwa seiring waktu berjalan kandungan COD akan semakin sedikit, begitu pula listrik yang dihasilkan akan semakin rendah. Maharaj dan Parneet (2015) juga menyebutkan bahwa ada korelasi linier antara nilai material organik dengan energi listrik yang dihasilkan yang disebabkan oleh bakteri yang menempel pada permukaan anoda beraktivitas mendegradasi material organik dalam kondisi anaerobik.…”

Microbial fuel cell (MFC) is a technology that can produce electricity with helping exoelectrogenic bacteria. The technology can also utilize fishery processing wastewater as a media for bacteria to live, so it can reduce organic pollution load in the wastewater. Purpose of this research was to identify the effect of electrodes distance to electricity and water quality parameters of fisheries processing wastewater using MFC technology.. The MFC system used was single chamber system. The distance between electrodes used were 2 cm, 4 cm and 6 cm and the electrodes were made of stainless wire mesh coated with chitosan and active carbon. The results showed that electrodes distance affected to MFC electricity within salted boiled fish wastewater media. The average value of electric current during 48 hours observation on the distance of 2 cm, 4 cm and 6 cm were 0.17±0.06 mA, 0.46±0.17 mA and 0.44±0.16 mA, respectively. Average values of electric voltage on the distance of 2 cm, 4 cm and 6 cm were 0.12±0.03 V, 0.34±0.07 V and 0.37±0.08 V, respectively. The research also showed that MFC system can decrease average value of BOD 20.5%, COD 30.41%, and TAN 21.2 % of salted boiled fish wastewater media.
