What is microbial fuel cell?
A microbial fuel cell (MFC) is a bioelectrochemical device that can generate electricity by the use of electrons obtained from the anaerobic oxidation of substrates. Generally, the MFC consists of two parts, an anode and a cathode, which are separated by a proton exchange membrane (PEM).
What is MFC in biology?
Microbial fuel cell (MFC) is a type of bioelectrochemical fuel cell system that generates electric current by diverting electrons produced from the microbial oxidation of reduced compounds (also known as fuel or electron donor) on the anode to oxidized compounds (also known as oxidizing agent or electron acceptor) on …
What is a fuel cell in simple terms?
A fuel cell is a device that generates electricity through an electrochemical reaction, not combustion. In a fuel cell, hydrogen and oxygen are combined to generate electricity, heat, and water.
How does an MFC work?
Just like an ordinary battery, an MFC uses chemical energy to generate electricity. An MFC has two electrodes held in separate chambers. The anode chamber that contains the bacteria is anaerobic. This takes advantage of the oxidation that bacteria carry out naturally during cellular respiration.
What microbes are used in microbial fuel cells?
Gram-negative microorganisms used in MFC are presented Bacillus violaceus, Escherichia coli, Pseudomonas fluorescens, Proteus vulgaris, Pseudomonas methanica, Desulfuromonas acetoxidans, Geobacter sulfurreducens, Methylovorus dichloromethanicum, Methylovorus mays, Shewanella putrefaciens, Geobacter metallireducens.
What microbes are used in microbial fuel cell?
What is mediator less microbial fuel cell?
Microbial fuel cell (MFC) is an approach to wastewater treatment that converts organic matter in the wastewater into electricity (Kim et al. 2002. A mediator-less microbial fuel cell using a metal reducing bacterium, Shewanella putrefaciens. Enzyme Microb.
What are the different types of fuel cells?

What is fuel cell in chemistry?
A fuel cell is an electrochemical cell that converts the chemical energy of a fuel (often hydrogen) and an oxidizing agent (often oxygen) into electricity through a pair of redox reactions. Since then, fuel cells have been used in many other applications.
Why microbial fuel cells are considered a source of sustainable energy?
1. They use living organisms as catalysts to generate electricity from certain substrates. 2. They can be installed in waste water treatment plants to cleanse water and produce electricity.
Why microorganisms are used in bioremediation?
The application of bioremediation as a biotechnological process involving microorganisms for solving and removing dangers of many pollutants through biodegradation from the environment. Microorganisms are restoring the original natural surroundings and preventing further pollution .
What are some examples of fuel cells?
Different types of fuel cells include polymer electrolyte membrane ( PEM ) Fuel Cells, direct methanol fuel cells, phosphoric acid fuel cells, molten carbonate fuel cells, solid oxide fuel cells, reformed methanol fuel cell and Regenerative Fuel Cells.
What is micro fuel cell?
A micro fuel cell is a power source for electronic devices that converts chemical energy into electrical energy. Fuel cells operate by oxidizing combustible fuel, such as hydrogen or alcohol.
What is microbial fuel?
A microbial fuel cell (MFC) is a bio-electrochemical device that harnesses the power of respiring microbes to convert organic substrates directly into electrical energy. At its core, the MFC is a fuel cell, which transforms chemical energy into electricity using oxidation reduction reactions.
What are microbial cells?
A microbial fuel cell (MFC) is a device that converts chemical energy to electrical energy by the action of microorganisms. These electrochemical cells are constructed using either a bioanode and/or a biocathode.
