Opening size optimization of metal matrix in rolling-pressed activated carbon air–cathode for microbial fuel cells

Performance assessment of partially sulfonated PVdF-co-HFP as polymer electrolyte membranes in single chambered microbial fuel cells

“…Internal resistance of the whole cell was segmented in various component specific resistances, like activation resistance, ohmic resistance (attributed to electrode resistance, membrane resistance, etc.) and concentration resistance [34,35]. The ohmic resistance as calculated from the EIS graphs were found to be $11.4 O for MFC-A, $7.8 O for MFC-B, $13.2 O for MFC-C, and $27.3 O for MFC-D.…”

Sand amendment enhances bioelectrochemical remediation of petroleum hydrocarbon contaminated soil

“…The carbon meshes (6 cm  6 cm, Jilin Carbon Factory, Jilin, China) were cleaned by acetone overnight followed by rinsing with distilled water for three times (Wang et al, 2009). The AC air-cathode (6 cm  6 cm) was made by rolling-press method according to previous descriptions (Dong et al, 2013;Li et al, 2014c). The catalyst layer of the cathode contacted the soil, while the gas diffusion layer faced to the air.…”

“…The Nyquist plots were used to interpret the spectra. A fitting program (ZsimpWin 3.10) was employed to simulate plots according to an equivalent circuit (Li et al, 2014c). Cell voltages (U in mV, 1000 X of external loading) were recorded using a data acquisition system (PISO-813, ICP DAS Co., Ltd, Shanghai, China) every 1800 s (t).…”

Simultaneous electricity generation and microbially-assisted electrosynthesis in ceramic MFCs

“…In addition, the electrode material is another critical factor of the MFC architecture that plays an important role in performance, cost of production and preparation, as well as longevity and maintenance. In this respect, activated carbon based cathodes are inexpensive and useful alternatives to Pt-catalysed electrodes in MFCs [21][22][23][24].…”
