MICROBIAL FUEL CELL FOR GENERATING ELECTRICITY FROM WASTEWATER Russian patent published in 2023 - IPC H01M8/16 

FIELD: electrical engineering; microbial fuel cells.

SUBSTANCE: invention relates to a microbial fuel cell in which the oxidation reaction of organic compounds to carbon dioxide, catalysed by electrogenic bacteria, is carried out, and can be used to generate electricity with a continuous supply of a nutrient medium for electrogenic bacteria (substrate), including domestic wastewater. Increasing the power density and cell stability is a technical result that is achieved due to the fact that in a microbial fuel cell with inputs and outputs for continuous supply of reagents, consisting of cathode and anode half-cells separated by an anion exchange membrane, the anode is made of carbon felt modified with polypyrrole, anthraquinone disulfonic acid and a biofilm of electrogenic bacteria. A biofilm with a conductive polymer inoculated into the surface of the anode, containing electrogenic bacteria, facilitates the oxidation of organic substances and increases the stability of the anode material during cell operation.

EFFECT: increasing the power density and cell stability.
