A bioelectrochemical fuel cell system called a “microbial fuel cell,” also referred to as a “micro fuel cell,” uses an external electrical circuit to direct electrons produced by microbial oxidation of reduced compounds on the anode to oxidized compounds like oxygen on the cathode in order to produce electricity.
Microorganisms act as biocatalysts in microbial fuel cells (MFCs), which are non-combustive devices that generate electricity by using organic materials as substrate. The substrate is broken down by these living bacteria, converting chemical energy into usable electrical energy. It can be used in many different industries, including wastewater treatment, bio-recovery, and power generation systems.
The Global microbial fuel cell market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Microbes are dynamic organisms that are involved in the development of numerous cutting-edge technologies. Microbial fuel cells (MFC) are one such emerging technology that can generate electricity from organic waste while lowering carbon footprint and environmental degradation.
This technique has been embraced by numerous companies for use in a variety of fields, including wastewater treatment, bioenergy generation, and biosensors. Sporomusa ovata, a Gram-negative anaerobic bacteria that ferments carbon dioxide and hydrogen to acetate, is one of the promising microorganisms that generates electric current.
The energy consumption of wastewater treatment plants is greatly reduced by MFC in contrast to conventional approaches. MFC achieves this by utilizing electroactive microorganisms that can oxidize organic materials and transferring the liberated electrons to a solid electron acceptor, such as an electrode-anode.
The development of materials like catalysts, electrodes, and membranes, as well as the understanding of biofilm dynamics (pure or mixed culture microorganisms, extracellular electron transfer, and interface features), have helped lower production costs and boost the effectiveness of the technology.
Energy is generated through electron donations to the anode by organisms that reduce electrons. In order to generate electricity, MFC makes use of a number of microorganisms that may catalyze electrochemical oxidation or oxidation/reduction reactions.
