An enzymatic biofuel cell is a specific type of fuel cell that uses enzymes as a catalyst to oxidize its fuel, rather than precious metals. Enzymatic biofuel cells, while currently confined to research facilities, are widely prized for the promise they hold in terms of their relatively inexpensive components and fuels, as well as a potential power source for bionic implants.
A biofuel cell uses living organisms to produce electricity. It may refer to: Microbial fuel cell, a bio-electrochemical system that drives a current by using bacteria and mimicking bacterial interactions found in nature; Enzymatic biofuel cell, a type of fuel cell that uses enzymes rather than precious metals as a catalyst to oxidize its fuel
Fuel cells can be used with low-quality gas from landfills or waste-water treatment plants to generate power and lower methane emissions. A 2.8 MW fuel cell plant in California is said to be the largest of the type. [92] Small-scale (sub-5kWhr) fuel cells are being developed for use in residential off-grid deployment. [93]
Microbial fuel cell (MFC) is a type of bioelectrochemical fuel cell system [1] also known as micro fuel cell 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 such as oxygen (also known as oxidizing agent or electron acceptor) on the cathode through an ...
The cellulase family of enzymes have a one to two order smaller magnitude of efficiency. Therefore, it requires 40 to 100 times more of the enzyme to be present in its production. For each ton of biomass it requires 15-25 kilograms of enzyme. [72] More recent estimates [73] are lower, suggesting 1 kg of enzyme per dry tonne of biomass feedstock ...
"Biofuel production shall follow international treaties and national laws regarding such things as air quality, water resources, agricultural practices, labor conditions, and more. Biofuels projects shall be designed and operated in participatory processes that involve all relevant stakeholders in planning and monitoring.

Microbial electrochemical technologies (METs) use microorganisms as electrochemical catalyst, merging the microbial metabolism with electrochemical processes for the production of bioelectricity, biofuels, H 2 and other valuable chemicals.
