Comparison of oxygen and hypochlorite as cathodic electron acceptor in microbial fuel cells

Nickel oxide and carbon nanotube composite (NiO/CNT) as a novel cathode non-precious metal catalyst in microbial fuel cells

“…Most of the MFCs consist of two chambers (Sun, 2012), an anaerobic anode and corresponding cathode, separated by ion exchange membrane (IEM) (Kim et al, 2009). Air-cathode MFCs with simple singlechamber are typically considered as promising configuration for wastewater treatment applications (Ahn, 2013;Bidart et al, 2014;Liu et al, 2004) due to the oxygen as electron acceptor is cost effective, constantly replenishment, high redox potential and available to harvest (Jadhav et al, 2014).…”

Fe/N-doped graphene with rod-like CNTs as an air-cathode catalyst in microbial fuel cells

“…1 Aircathode MFCs with a simple single-chamber are typically considered as a promising conguration for wastewater treatment applications, [2][3][4] since the oxygen as electron acceptor is constantly replenishment, cost effective and high redox potential of oxygen reduction. 5 However, without catalysts the rate of the oxygen reaction reduction (ORR) is very low resulting in the poor performance of air-cathode MFCs. 6 In recent years, Fe-N/C catalysts have received increasing attention due to their high activity toward ORR and superior stability and low cost compared to commercial Pt-based catalysts.…”

Electricity production from human urine in ceramic microbial fuel cells with alternative non-fluorinated polymer binders for cathode construction

“…Ceramic materials have been applied in several MFC configuration types in a wide variety of shapes, not only as separators but also for electrode construction. These ceramic materials include earthenware, clayware and terracotta [9][10][11]. The application of porcelain material as proton exchange membrane was first reported by Park and Zeikus [12].…”
