What is the use of earthen pot in MFC?

The use of earthen pots in Microbial Fuel Cells (MFCs) is an innovative and sustainable approach for wastewater treatment and electricity generation. Here's how earthen pots are used in MFCs:

Porous Structure: Earthen pots have a porous structure that allows for the movement of ions and microorganisms. The pores provide a suitable environment for the growth of electrochemically active bacteria (EAB) that play a crucial role in generating electricity in MFCs.

Cost-effectiveness: Earthen pots are cost-effective compared to other materials commonly used in MFCs. They are readily available, especially in rural areas, and their production involves minimal energy consumption and environmental impact.

Versatile Design: The shape and size of earthen pots can be easily customized to suit the specific requirements of different MFC designs. They can be used as standalone units or integrated into larger-scale MFC systems.

High Surface Area: The inner surface of earthen pots provides a high surface area for microbial colonization. This allows for a greater density of EAB, leading to enhanced electricity generation and improved wastewater treatment efficiency.

Natural Buffering Capacity: Earthen pots have a natural buffering capacity, which helps maintain a stable pH within the MFC. This is crucial as EAB are sensitive to pH changes, and fluctuations can affect their metabolic activities and electricity production.

Environmental Friendliness: Earthen pots are made from natural clay and are biodegradable. After their use in MFCs, they can be safely disposed of without causing any harm to the environment.

Heat Insulation Properties: Earthen pots have heat insulation properties, which can be advantageous in maintaining a stable temperature within the MFC. This is particularly important in regions with fluctuating ambient temperatures, as EAB perform optimally within a specific temperature range.

Overall, earthen pots offer several advantages as a sustainable and cost-effective material for use in Microbial Fuel Cells. They contribute to efficient wastewater treatment and electricity generation while being environmentally friendly and easy to incorporate into MFC designs.
