Simultaneous electricity generation and microbially-assisted electrosynthesis in ceramic MFCs

摘要: Microbial Fuel Cells (MFCs) are bio-electrochemical transducers that generate electricity as a direct result of microbial metabolism, when breaking down organic matter for continuous growth and maintenance. On the other hand, Electrolysis (MECs) consume to drive chemical reactions recover hydrogen or high value chemicals, at cathode half-cell [1]. In MFCs, electric current is generated every electron donated electrode surface, proton transferred from anode cathode. Other cations such Na+ K+ may be present in significantly higher concentrations more likely through cation exchange membrane [2]. This normally results electro-osmotically dragged water cathode, often phenomenon known flooding, which problem MFCs fuel cells. To this day, bio-electrosynthesis has not been reported energy-generating since it associated with energy-consuming MECs. The main aim work was therefore investigate effects on MFC performance low-cost catalyst-free materials, conjunction transport half-cell, context beneficial accumulation recovery valuable resources.
