“…These salts could inhibit proton transfer by limiting the rate of oxygen reduction 33. Behera et al 11. noticed a power performance decrease in earthenware MFCs, explained by the increase of bio‐film growth on the cathode and a similar decrease is observed commonly for enzymatic bio‐fuel cells 34.…”

Microbial fuel cells (MFCs) made with different types of ceramic membranes were investigated to find a low‐cost alternative to commercially available proton exchange membranes. The MFCs operated with fresh human urine as the fuel. Pyrophyllite and earthenware produced the best performance to reach power densities of 6.93 and 6.85 W m−3, respectively, whereas mullite and alumina achieved power densities of 4.98 and 2.60 W m−3, respectively. The results indicate the dependence of bio‐film growth and activity on the type of ceramic membrane applied. The most favourable conditions were created in earthenware MFCs. The performance of the ceramic membranes was related to their physical and chemical properties determined by environmental scanning electron microscopy and energy dispersive X‐ray spectroscopy. The cost of mullite, earthenware, pyrophyllite and alumina was estimated to be 13.61, 4.14, 387.96 and 177.03 GBP m−2, respectively. The results indicate that earthenware and mullite are good substitutes for commercially available proton exchange membranes, which makes the MFC technology accessible in developing countries.

“…Attempts are currently underway to produce low cost MFCs constructed from earthen pots for use in India [16]. By removing the proton permeable membrane, utilizing locally produced 400 ml earthen pots, stainless steel mesh cathodes and a graphite plate anode, each MFC unit could be produced for US $1.…”

Microbial Fuel Cells, A Current Review

Microbial fuel cells (MFCs) are devices that can use bacterial metabolism to produce an electrical current from a wide range organic substrates. Due to the promise of sustainable energy production from organic wastes, research has intensified in this field in the last few years. While holding great promise only a few marine sediment MFCs have been used practically, providing current for low power devices. To further improve MFC technology an understanding of the limitations and microbiology of these systems is required. Some researchers are uncovering that the greatest value of MFC technology may not be the production of electricity but the ability of electrode associated microbes to degrade wastes and toxic chemicals. We conclude that for further development of MFC applications, a greater focus on understanding the microbial processes in MFC systems is required.

“…Before packing into the chambers, the carbon cloth electrodes were submerged in 1 N HCl for 24 h, washed with deionized water, then submerged in 1 N NaOH for 24h and finally washed several times in deionized water [11]. Anode was completely submerged by it; copper wires were used for contact with the external circuit [12]. A fix external resistance (1000 Ω) was used to facilitate the comparison of the electricity production in different treatments.…”

A microbial fuel cell (MFC) with an algae-assisted cathode is a low-cost and sustainable way to provide the oxygen for the oxygen reduction reaction. The anode was with anaerobic microorganism, a kind of photosynthetic bacteria (PSB-B). An algae bioreactor was connected to cathode microbial fuel cells to increase power generation by supplying more oxygen to cathode electrode. In this study, we used red, blue and white LED light as the light source, and the anode and cathode were under irradiation respectively. The result showed that white LED light was an effective factor for the anode, the cell voltage was built up from 34 mv to 60 mv, power density increased up to 2.5 mW/m 2 , the red and blue light had positive impact on the voltage. At cathode, the voltage was almost on steady stage conditions, and it was fluctuated around 35 mv by oxygen bubbles that were produced by algae. This relatively simple method increased the oxygen reduction rate at a low cost and could be applied to improve the performance of MFC. Subject AreasMicrobiology
