“…Another architectural parameter that leads to better performances is the active electrode surface area: the more active electrode area available, the more bioelectricity generation guaranteed for a given volume of the cell. Several works have investigated the use of reticulated and granular conductive carbon instead of flat electrodes, but sometimes their heavy and relatively low porosities slow metabolic and kinetics reactions for both biofilm and nutrients flow clogging 39 40 41 .…”

In contemporary society we observe an everlasting permeation of electron devices, smartphones, portable computing tools. The tiniest living organisms on Earth could become the key to address this challenge: energy generation by bacterial processes from renewable stocks/waste through devices such as microbial fuel cells (MFCs). However, the application of this solution was limited by a moderately low efficiency. We explored the limits, if any, of additive manufacturing (AM) technology to fabricate a fully AM-based powering device, exploiting low density, open porosities able to host the microbes, systems easy to fuel continuously and to run safely. We obtained an optimal energy recovery close to 3 kWh m−3 per day that can power sensors and low-power appliances, allowing data processing and transmission from remote/harsh environments.

“…Although it is meaningless to compare performance of MFCs with different design because other factors like separator surface area (Oh and Logan, 2006) and reactor architecture also influence MFC performance (Vázquez-Larios et al, 2011), these results nonetheless clearly show that earthen pot can replace PEM in MFC application.…”

“…Even though direct comparison of published MET performance data is not feasible since the reactor architecture influences greatly MET performance (Vázquez-Larios et al, 2011), but the comparison can yield useful information. Table 1 summarizes performance data of MFCs with different separators.…”

“…To the best of our knowledge studies on leachate treatment in MFCs seeded with enriched inocula are very scarce in the open literature [49]. There are, however, a couple of articles of our own group that deals with leachate treatment in MFC using more conventional inocula (aerobic, methanogenic, sulphate-reducing consortia) as well as research carried out by others whose results in general show low powers and moderate to adequate pollutant concentration removal (as chemical oxygen demand (COD)) (see review in appendix A, Supporting Information (SI)) [5,6,[50][51][52][53].…”

This work aimed at evaluating the effect of four anodic materials and the use of enriched inocula on the microbial fuel cell (MFC) performance. The anodic materials were granular activated carbon (GAC), graphite rod (GR), triangles of graphite (GT) and graphite flakes (GF). When loaded with a sulfate-reducing inoculum (SR-In) the internal resistance (Rint) obtained were 273, 410 and 795 Ω for GF, GT, GR, respectively and higher than 10 000 Ω for GAC, whereas the maximum volumetric power (PV,max) were 1326, 2108 and 3052 mW m-3 for GR, GT and GF, respectively. We observed a decrease of Rint and an increase of PV,max with the increase of the log of A´s of the graphite anodic materials that was consistent with a mathematical model previously reported by our Group. The use of the Fe (III)-reducing inoculum significantly enhanced the MFC performance; PV,max was up to 5000 mW m-3, 40% higher than the power obtained with SR-In whereas the Rint was 140 ohms. Highest PVs of our MFC were close to values of electricity power derived from the anaerobic digestion of municipal wastewaters. In this regard, results of this work point out to a promising approach to further tapping bioelectricity from organic wastes that previously have yielded biohydrogen.
