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...
متن کاملEquivalent Electrical Circuit Modeling of Ceramic-Based Microbial Fuel Cells Using the Electrochemical Impedance Spectroscopy (EIS) Analysis
The effect of the thickness of ceramic membrane on the productivity of microbial fuel cells (MFCs) was investigated with respect to the electricity generation and domestic wastewater treatment efficiencies. The thickest ceramic membrane (9 mm) gained the highest coulombic efficiency (27.58±4.2 %), voltage (681.15±33.1 mV), and current and power densities (447.11±21.37 mA/m2, 63.82±10.42 mW/m2) ...
متن کاملBiological capacitance studies of anodes in microbial fuel cells using electrochemical impedance spectroscopy.
It is known that cell potential increases while anode resistance decreases during the start-up of microbial fuel cells (MFCs). Biological capacitance, defined as the apparent capacitance attributed to biological activity including biofilm production, plays a role in this phenomenon. In this research, electrochemical impedance spectroscopy was employed to study anode capacitance and resistance d...

متن کاملCharacterization of antimicrobial peptide activity by electrochemical impedance spectroscopy.
Electrochemical impedance spectroscopy performed on surface-supported bilayer membranes allows for the monitoring of changes in membrane properties, such as thickness, ion permeability, and homogeneity, after exposure to antimicrobial peptides (AMPs). We show that two model cationic peptides, very similar in sequence but different in activity, induce dramatically different changes in membrane p...
