Microbial fuel cells (MFCs) represent a clean and renewable energy resource. To date, power generation in MFCs is severely limited. In order to improve performance, a wide range of techniques have been utilised for a fundamental scientific understanding of the components and processes and also to investigate MFC performance bottlenecks. This tutorial article reviews the electrochemical/electroanalytical techniques employed in recent MFC studies and discusses the principles, experimental implementation, data processing requirements, capabilities, and weaknesses of these techniques.2

Resumo. Processos alternativos para a geração de energia podem ter interesses tanto ambientais quanto econômicos. Um destes processos é a utilização de célula combustível microbiana (CCM), que são reatores capazes de promover a conversão da energia química presente na matéria orgânica em energia elétrica por meio de micro-organismos. Baseado neste processo, o presente trabalho teve por objetivo avaliar a influência de um tensoativo aniônico em CCM com e sem membrana, inoculadas com lodo de fossa séptica. Os eletrodos utilizados foram hastes de grafite e as CCM foram alimentadas com substrato sintético e mantidas em temperatura ambiente. As CCM foram monitoradas quanto a corrente e tensão elétrica gerada durante 35 dias. Observou-se que a presença da membrana e adição de LAS favoreceram a geração de energia. A adição de LAS influenciou positivamente na geração de energia elétrica, na CCM sem membrana a maior densidade de corrente foi de 7,5 mA/m 2 e para a CCM com membrana foi de 37,3 mA/m 2 .Palavras-chaves: Bioenergia.

One these process is the use of microbial fuel cells (MFC), characterized by reactors that are able to promote the conversion of chemical energy present in the organic matter into electrical power by microorganisms. Based on this process, this study aimed to evaluate the influence of an anionic surfactant in MFC with and without membrane, inoculated with septic tank sludge. The electrodes used were graphite rods and were fed synthetic substrate and maintained at room temperature. The MFC were monitored for current and voltage generated during 35 days. It was observed that the presence of the membrane and addition of LAS favored the generation of energy. The addition of LAS positively influenced the generation of electricity, the CCM without membrane most current density was 7.5 mA/m 2 and the CCM membrane was 37.3 mA/m 2 .

Abstract-Microbial fuel cells (MFCs) are promising clean energy sources for simultaneous recycling of organic waste while harvesting electricity. As for the different effects of electrode materials on the power performance of MFCs, a new material of electrode, carbon nanotube/polyaniline carbon paper (CNT/PANI carbon paper) was utilized and compared with other traditional carbon paper/cloth in this study. Results show that a lower ohmic loss and a better power performance were executed by using CNT/PANI carbon paper. These findings further exhibit its feasibility to improvement of power performance in MFCs.Index Terms-Electrode, microbial fuel cells, carbon nanotube / polyaniline carbon paper. I. INTRODUCTIONThe exhaustion of petroleum stores and the impending energy crisis will result in the future destruction of the environment. To help prevent this, seeking clean and renewable energy to replace traditional petrochemical energy has been continued. Here, the microbial fuel cells (MFCs) are one of green energy sources because MFCs uses microorganisms as a substrate and possesses active electrodes using the microorganism metabolism to produce electricity. The working principle of a microbial fuel cell is similar to that of a fuel cell. But, the main difference between them is the microorganisms' function in the microbial fuel cell to carry out the energy conversion [1].The microbial fuel cell can be divided into direct microbial fuel cells and indirect ones [2]-[4]. A typical MFC consists of an anode chamber and a cathode chamber separated by a proton exchange membrane (PEM) whose available source is multiple [4]- [7]. As for the electrode materials, graphite particles, graphite felt, carbon paper, carbon cloth, reticulated vitreous carbon (RVC) and carbon brush were often used previously.Concerning the feature of different electrode material resulting in different activation polarization losses [1], [2], Pt and Pt black electrodes are superior to graphite, graphite felt and carbon cloth electrodes for power performance, but their costs are much higher [8]. Schröder et al.,[9] reported that using a platinumized carbon cloth electrode in E. coli MFC with a current density of 0.84mA/cm 2 would be greater than Manuscript received October 23, 2012; revised January 18, 2013.
