“…You et al [18] created a graphite-granule anode with a tubular aircathode MFC (GTMFC), which was capable of continuous electricity generation from glucose-based substrates. This GTMFC produced a maximum volumetric power of 50.2 Wm -3 at a current density of 216 A m -3 .…”

A membrane-free fluidized-bed microbial fuel cell (FB-MFC) was applied to investigate the effects of fluidization parameters on its electrogenesis capacity. Active carbon particles were found to significantly decrease the start-up time and increase the output voltage of the FB-MFC. The fluidization behavior of the active carbon particles in the FB-MFC reactor is one of the key parameters that influence the generation of electricity. With the FB-MFC operating under optimal conditions, maximum power density with minimal internal resistance of the MFC could be obtained. The FB-MFC could be operated in large-scale wastewater treatment processes with high chemical oxygen demand removal efficiencies.

“…Several types of electrocatalysts, such as platinum [3,13,14] or metal-based CoTMPP [15], are needed to decrease overpotential during interfacing electrocatalysed reactions of oxygen in the cathode. These electrocatalysts, however, are often expensive or time-consuming in preparation, and sensitive to poisoning [10].…”

To improve cathodic efficiency and sustainability of microbial fuel cell (MFC), graphite fibre brush (GFB) was examined as cathode material for power production in biocatalysed‐cathode MFC. Following 133‐h mixed culturing of electricity‐producing bacteria, the MFC could generate a reproducible voltage of 0.4 V at external resistance (REX) of 100 Ω. Maximum volumetric power density of 68.4 W m–3 was obtained at a current density of 178.6 A m–3. Upon aerobic inoculation of electrochemically active bacteria, charge transfer resistance of the cathode was decreased from 188 to 17 Ω as indicated by electrochemical impedance spectroscopy (EIS) analysis. Comparing investigations of different cathode materials demonstrated that biocatalysed GFB had better performance in terms of half‐cell polarisation, power and Coulombic efficiency (CE) over other tested materials. Additionally, pH deviation of electrolyte in anode and cathode was also observed. This study provides a demonstration of GFB used as biocathode material in MFC for more efficient and sustainable electricity recovery from organic substances.

“…[27] As shown in Table 1, the glucose concentration of the anaerobic medium affected the current density and H 2 O 2 formation rate (concentration) in accordance with saturation-like kinetics. [28] The close correlation between H 2 O 2 formation and initial glucose concentration confirmed that the current and H 2 O 2 originated from glucose oxidation. Gaseous H 2 , as an important intermediate, is not soluble in water at 303.15 K, so an increase in H 2 partial pressure resulting from glucose oxidation drives H 2 diffusion across the PTFE layer onto an electroactive site, where it is consumed.…”
