What are the applications of microbial fuel cell?

What are the applications of microbial fuel cell?

One such developing technology is microbial fuel cells (MFC) that can produce electricity from organic waste and reduce carbon footprint and environmental pollution. Many industries have adopted this technology for various applications such as wastewater treatment, bioenergy production, and biosensors.

What are the types of MFC?

MFCs are of different types; however, the basic designs used in the laboratories for its applications include double-chamber MFC, single-chamber MFC, upflow MFC and stacked MFC. Moreover, some other designs have also been used for the studies.

How do you set up a microbial fuel cell?

How to make your own microbial fuel cell

1. Materials.
2. Get drilling. Drill a hole for the copper wire in the lid of each container.
3. Coil the graphite. Strip the ends of two pieces of copper wire and wrap one around each pencil lead.
4. Mix the solution.
5. Squeeze the oxygen.
6. Feed the microbes.

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.

Which bacteria are used in microbial fuel cells?

The best microorganism for producing an electric current is Sporomusa ovata, which is an anaerobic, Gram-negative bacterium that converts hydrogen and carbon dioxide to acetate by fermentation. In comparison to a standard hydrogen electrode, this fuel cell produces −400 mV.

Which bacteria is used in MFC?

Power generation with MFC was demonstrated with one species of bacterium (Escherichia coli) and one species of yeast (Saccharomyces cerevisiae).

What is a microbial electric cell?

A microbial electrolysis cell (MEC) is a technology related to Microbial fuel cells (MFC). Whilst MFCs produce an electric current from the microbial decomposition of organic compounds, MECs partially reverse the process to generate hydrogen or methane from organic material by applying an electric current.

How much power can a microbial fuel cell produce?

The power density that an MFC can typically generate is from 1 to 2000 mW m−24. Therefore, the MFC output voltage and power must be increased for practical uses. So far, several MFCs were simply connected in series or in parallel to overcome the low voltage or power issue.

How much does a microbial fuel cell cost?

000 gpd is $70 per gpd of treatment capacity. It was estimated that the capital cost of this 200 L MFC system was about $58 per gpd of treatment capacity.
