Abstract

Mediator-less microbial fuel cells (MFC) enriched with oligotrophic microbes were optimized through enhancement of cathode reaction and lowering O2 diffusion into the anode compartment as a low BOD sensor. The optimization of the MFC has greatly improved the maximum current and coulomb yield. The oligotroph-type MFC could be used as a low BOD sensor with high operational stability, good repeatability and reproducibility.

Interface resistances of anion exchange membranes in microbial fuel cells with low ionic strength

“…For example, oxygen is known to transfer from the cathode chamber to the anode chamber through a Nafion membrane, which reduces electricity generation at the anode, because the anode-respiring bacteria use oxygen preferentially over the anode as the electron acceptor (Kang et al, 2003;Pham et al, 2004). Thus, we evaluated the transport of oxygen and acetate through the AEMs.…”

Development and Long-Term Stability of a Novel Microbial Fuel Cell BOD Sensor with MnO2 Catalyst

“…So far, most sensors reported in the literature have made use of expensive platinum [19,20,21]. However, considering the high cost and low durability of platinum due to corrosion and degradation of catalytic activity over time [22], alternative metal catalysts such as indium/tin [23], cobalt [24], titanium [25], tungsten [26], or manganese [27] should be sought.…”

Standardized Characterization of a Flow Through Microbial Fuel Cell

“…Other labs have elected to report current [26] or current density normalized to surface area [27][28][29][30] as a function of time, or as absolute power [15,16] or power normalized to electrode surface area [31] as a function of current. Power density as a function of current density (normalized to surface area) [32][33][34] or absolute current [35] has also been reported.…”
