Low-cost separators for enhanced power production and field application of microbial fuel cells (MFCs)

Performance of a greywater cathode in a microbial fuel cell with three ion exchange membranes

“…The ohmic resistance ( R Ω ) was similar between cells in the same stack (Table ). This is due to the same materials being implemented as electrodes, membrane, connections and reactor design, which are factors that determine the R Ω . The difference observed in R Ω in the different stacks is attributed to the membrane type used, which is the only different material used between stacks of double chamber design, as was observed in a previous study, which obtained R Ω of 37 Ω y 19 Ω for two cells using the AEM AMI‐7001 and CEM Nafion® 117, respectively …”

Ethanolamine degradation and energy recovery using a single air-cathode microbial fuel cell with various separators

“…Kondaveeti et al (2014) reported that proton mass transfer, diffusion coefficient and ion transport of the CEM were higher than them of the Nafion. Furthermore, in permselectivity test for Nafion and CEM, the Nafion was lower than the CEM (Grossi and Chao, 2014).…”

Minimum interspatial electrode spacing to optimize air-cathode microbial fuel cell operation with a membrane electrode assembly

“…Ohmic resistance was determined by noting the real axis values at a high-frequency intercept [18]. Anode and cathode potentials were measured against the Ag/AgCl (+197 vs SHE) reference electrode (Basi Inc., USA) at OCV.…”

“…The membranes used should not allow oxygen to diffuse from the cathode to the anode compartment [18]. The oxygen mass transfer and diffusion coefficients were determined using a dissolved oxygen probe (Orion A323; Thermo Scientific Co., USA) in an uninoculated MFC.…”

“…Anode and cathode potentials were measured against the Ag/AgCl (+197 vs SHE) reference electrode (Basi Inc., USA) at OCV. Columbic efficiency was calculated as described previously [18].…”
