  • Challenges in Microbial Fuel Cell development and operation
    Applied Microbiology and Biotechnology, 2007
    Co-Authors: Byung Hong Kim, In Seop Chang, Geoffrey M. Gadd
    Abstract:

    A Microbial Fuel Cell (MFC) is a device that converts chemical energy into electricity through the catalytic activities of microorganisms. Although there is great potential of MFCs as an alternative energy source, novel wastewater treatment process, and biosensor for oxygen and pollutants, extensive optimization is required to exploit the maximum Microbial potential. In this article, the main limiting factors of MFC operation are identified and suggestions are made to improve performance.

  • Improved Performance of Microbial Fuel Cell Using Membrane-Electrode Assembly
    Journal of Microbiology and Biotechnology, 2005
    Co-Authors: Jae Kyung Jang, In Seop Chang, Hyun Soo Moon, Byung Hong Kim
    Abstract:

    A mediator-less Microbial Fuel Cell (MFC) was used to determine the performance effects of a membrane­electrode assembly (MEA). The MFC with an MEA generated a higher current with an increased coulomb yield when compared to an MFC with a separate cathode. Less oxygen was diffused through an MEA than through a Nafion membrane. The MFC performance was improved with a buffer, although a high-strength buffer reduced the performance.

  • improvement of cathode reaction of a mediatorless Microbial Fuel Cell
    Journal of Microbiology and Biotechnology, 2004
    Co-Authors: Jae Kyung Jang, In Seop Chang, Byung Hong Kim
    Abstract:

    Oxygen diffuses through the cation-specific membrane, reducing the coulomb yield of the Fuel Cell. In the present study, attempts were made to enhance current generation from the Fuel Cell by lowering the oxygen diffusion, including the uses of ferricyanide as a cathode mediator and of a platinum-coated graphite electrode. Ferricyanide did not act as a mediator as expected, but as an oxidant in the cathode compartment of the Microbial Fuel Cell. The Microbial Fuel Cell with platinum-coated graphite cathode generated a maximum current 3-4 times higher than the control Fuel Cell with graphite cathode, and the critical oxygen concentration of the former was 2.0 mg 1 -1 , whilst that of the latter was 6.6 mg 1 -1 . Based on these results, it was concluded that inexpensive electrodes are adequate for the construction of an economically feasible Microbial Fuel Cell with better performance as a novel wastewater treatment process.

  • novel bod biological oxygen demand sensor using mediator less Microbial Fuel Cell
    Biotechnology Letters, 2003
    Co-Authors: In Seop Chang, Hyung Soo Park
    Abstract:

    A Microbial Fuel Cell type of biosensor was used to determine the biochemical oxygen demand (BOD) of wastewater. The biosensor gave a good correlation between the BOD value and the coulomb produced. The BOD sensor has been operated for over 5 years in a stable manner without any servicing. This is much longer that that of previously reported BOD biosensors.

  • Algal-assisted Microbial Fuel Cell for Wastewater Treatment and Bioelectricity Generation
    Energy Sources Part A-recovery Utilization and Environmental Effects, 2014
    Co-Authors: Asheesh Kumar Yadav, B. C. Acharya, S K Nayak, Bijay K. Mishra
    Abstract:

    The aim of the present work was to design a self-sustainable, low-cost Microbial Fuel Cell using a blue green algae-assisted cathode as a substitute for chemical oxidant. The idea was to utilize the oxygen produced during photosynthesis by algae as an oxidant in the cathode chamber. Results successfully demonstrated that the algae-assisted Microbial Fuel Cell is efficient for electricity generation and chemical oxygen demand removal from wastewater. The performance of a developed Microbial Fuel Cell resulted in a maximum current density of 149.5 mA m−2 and power density of 78.12 mW m−2. Dissolved oxygen concentration in cathode solution achieved in the range of 3.5 to 5.5 mg l−1. Furthermore, other species of algae like oil-algae can be grown in a cathode chamber, which can be used for bio-diesel production and greenhouse gas like CO2 sequestering. Further works are under progress on this aspect in our research group.

  • performance assessment of innovative constructed wetland Microbial Fuel Cell for electricity production and dye removal
    Ecological Engineering, 2012
    Co-Authors: Asheesh Kumar Yadav, Purnanjali Dash, Ayusman Mohanty, Rouzbeh Abbassi, B K Mishra
    Abstract:

    This research work deals with performance assessment of constructed wetlands-Microbial Fuel Cell (CW-MFC) for electricity production and wastewater treatment. Microbial Fuel Cell consists of two chambers i.e. anaerobic and aerobic, where oxidation and reduction reactions take place. Constructed wetland also consists of aerobic and anaerobic zones where oxidation and reduction processes take place. These similarities in both technologies motivated us to design and develop a new type constructed wetland-Microbial Fuel Cell. In this CW-MFC, the removal of dye and COD were investigated along with electricity generation. Experiments were performed in batch mode using different dye (methylene blue dye) concentration containing synthetic wastewater. Our results show that 76.2, 80.87, 69.29 and 93.15 percentage dye removal could be achieved after 96h of treatment of wastewater containing 2000, 1500, 1000 and 500mgl -1 initial concentration respectively. Also, the CW-MFC is able to remove 75% of COD form wastewater with 1500mgl -1 initial concentration of dye. The maximum power density of 15.73mWm -2 and maximum current density of 69.75mAm -2 could be achieved during treatment of 1000mgl -1 initial dye concentration containing wastewater. © 2012 Elsevier B.V.

    Co-Authors: Gowthami Palanisamy, Hoyoung Jung, T Sadhasivam, Mahaveer D Kurkuri, Sang Chai Kim, Sunghee Roh
    Abstract:

    Abstract Microbial Fuel Cells have gained great interest as an alternative energy conversion system for generating bioenergy. As a bioelectrochemical hybrid system, Microbial Fuel Cells involved in electricity generation and wastewater treatment including nutrients recovery with tremendous benefits such as energy saving, reduced sludge generation and energy conversion. In this review, we mainly emphasize the developments and advancements of electrode and membrane materials for increasing the Microbial Fuel Cell performances in recent years. We reviewed and discussed the different categories of electrode (anode and cathode) materials with various structural, dimensional, compositions and integrations. Moreover, it encloses the cost-effective, biocompatible and highly stable electrode materials with improved Microbial Fuel Cell performance. Using hetero-atom doped 3-Dimensional porous carbon with ultra-fine metal nanoparticles, a large surface area of the electrode material with different dimensional, and new core@shell structure can considerably enhance the oxygen reduction reaction performance during the Microbial Fuel Cell operation. Following this overview, development in membrane materials such as perfluorinated polymer, hydrocarbon polymer, organic-organic hybrid polymer, organic-inorganic hybrid composite, ceramics, and biopolymer membranes are explained in detail. Based on the physical, chemical, mechanical and biocompatible properties, the hybrid composite biopolymer membrane with organic and inorganic additives are recommended as a suitable membrane candidate for increasing the ion conductivity and rectifying the biofouling issues during the long term operation. Finally, the future viewpoints in the Microbial Fuel Cell for effective wastewater treatment process with electricity generation are suggested through various aspects and strategies to afford clean energy and environment.
