Ohmic resistance affects microbial community and electrochemical kinetics in a multi-anode microbial electrochemical cell

Biochemical and Electrochemical Perspectives of the Anode of a Microbial Fuel Cell

Enzymatic and Microbial Electrochemical Systems

Enzymatic and microbial electrochemical systems (MESs) utilize the ability of biological components— enzymes and microbes—to catalyze an oxidation or reduction reaction at solid-state electrodes. A commonly known system is the microbial fuel cell in which electricity is produced via the microbially catalyzed oxidation of organic matter. The electrochemical systems that are discussed have a wide...

Microbial communities and electrochemical performance of titanium-based anodic electrodes in a microbial fuel cell.

Four types of titanium (Ti)-based electrodes were tested in the same microbial fuel cell (MFC) anodic compartment. Their electrochemical performances and the dominant microbial communities of the electrode biofilms were compared. The electrodes were identical in shape, macroscopic surface area, and core material but differed in either surface coating (Pt- or Ta-coated metal composites) or surfa...

Microbial ecology‐based engineering of Microbial Electrochemical Technologies

Microbial ecology is devoted to the understanding of dynamics, activity and interaction of microorganisms in natural and technical ecosystems. Bioelectrochemical systems represent important technical ecosystems, where microbial ecology is of highest importance for their function. However, whereas aspects of, for example, materials and reactor engineering are commonly perceived as highly relevan...

Electrochemical Impedance Spectroscopy for Microbial Fuel Cell Characterization

Electrochemical impedance spectroscopy is an efficient, non-intrusive and semi-quantitative technique to characterize the performance of bio-electrochemical systems such as microbial fuel cells and enzymatic fuel cells. Indeed, quantitative interpretation of the impedance data can be obtained with the help of mechanistic models using meaningful equivalent circuits. The production of maximum pow...
