This paper summarises different methods used for the Electrical power generation using microorganisms in Microbial Fuel Cell (MFC), where power generation is done in a microbial environment. Microorganisms are used as catalysts to degrade the supplied source effectively. This bioelectricity production is carried out in an enhanced way in a pollution-free environment. This paper addresses different aspects of electricity generation with the help of microorganisms. Various types of Microbial fuel cells have been described based on their constructional details. One of the different power generation methods is wastewater treatment. Also, hydrogen is generated in this environment, which can be used in fuel cells. Different factors and catalysts used to produce bioelectricity are identified and analyzed. Finally, the power produced in those methods had been compared, and the best method is cited.

Power Recovery

Wastewater treatment plants help removing organic matter from wastewater, and at the same time, generate digester gas as a useful byproduct. Digester gas is rich in methane, which can be used to generate electricity. Fuel cell systems are the cleanest technology for power recovery from digester gas, since all other technologies generate electricity by burning all the digester gas. The most commonly used type of fuel cell for power generation from digester gas in wastewater treatment plants is the molten carbonate fuel cell. This type of fuel cell can tolerate the impurities usually found in digester gas, such as CO2 and H2S; however, this kind of fuel cell systems is more suitable for large wastewater treatment plants. This prevents the use of fuel cells for power generation from digester gas in wastewater treatment plants serving medium and small size cities, or even farms. This research attempts to explore solutions to make fuel cell technologies technically and economically feasible for medium and small size wastewater treatment plants. The most suitable type of fuel cells for small applications is the Proton Exchange Membrane, PEM, fuel cell. The main challenge in using PEM fuel cells for power recovery from digester gas is that they are highly sensitive to impurities in its hydrogen gas supply. Therefore, in order to use PEM fuel cells in this application, energy must be spent in cleaning the digester gas before it enters the PEM fuel cell and reformer system. Energy is also required in the form of heat by the reformer system to produce the hydrogen needed by the fuel cell. Both the energy used in the cleaning of the digester gas and the hydrogen generation process comes from burning part of the digester gas. This reduces the amount of digester gas available for hydrogen production and electricity generation, respectively. The approach followed in this investigation seeks to develop a Simulink® model of the reformer and fuel cell so that the modeling tools of Matlab® can be used to simulate the performance of the system under different operating conditions. A sensitivity analysis is carried out to identify critical operating parameters affecting the performance of the overall system. The results obtained in this work provide guidelines for future studies of performance optimization and optimal control using the tools available in Matlab®, in order to get maximum electricity generation from digester gas using PEM fuel cell systems.

Microbial fuel cells (MFCs) set a new trend of converting chemical energy or bio energy to electricity from wastewater (domestic and industries) at the same time removal of chemical oxygen demand (COD) from the wastewater. Electrical energy generated from microbial fuel cell could be used for small electrical device example biosensors. The main components of MFCs are the anode, and the cathode salt bridge. It contains an anode chamber and a cathode chamber which separate electrodes for the production of electricity, using wastewater in an anaerobic chamber helps grow native microorganisms. Adding substrates increases productivity of the electrons that are moving from the anode chamber to the cathode chamber by help of the salt bridge. Bioreactors based on power generation in MFCs are a new approach to wastewater treatment. Power generation and current is modulated in this system. If it is optimised, MFCs would prove to be new method to offset wastewater treatment plant operating costs.
