Mains level: Alternative ways to generate electricity. Microbial fuel cells (MFCs) are a new bioelectrochemical process that aims to produce electricity by using the electrons derived from biochemical reactions catalyzed by bacteria. MFCs are scaled-down versions of the hydrogen fuel cells used in vehicles. The United States Naval Research Laboratory developed nanoporous membrane microbial fuel cells that use a non-PEM to generate passive diffusion within the cell. How it works? These sugars do not remain in the leaves, but are transported throughout the plant to the stem and roots. The energy generated by MFCs is expected to supply enough energy to partially cover the energy demand in urban WWTPs [2]. SMFCs produce electrical current from the organic matter content of sediments using bacterial metabolism. So if Vision IAS is doing that work for you, why overlap?
