The aim of the present study is to enhance the performance of a microbial fuel cell (MFC) design by making simple interventions. Specifically, terracotta “t” and mullite “m” ceramics are tested as membranes while carbon veil and carbon cloth are used as electrodes. In the case of “m” cylinders different dimensions are examined (m: ID 30 mm x height 11.5 mm; sm: ID 18 mm x height 18 mm). The units operated continuously with urine as the feedstock. The best performing is the sm type (60–100 μW), followed by the t type (40–80 μW) and the m type (20–40 μW). Polarisation experiments indicated that activated carbon on the anode enhances the power output (t: 423 μW, sm: 288 μW). Similarly, the increase of the surface area and the addition of stainless steel mesh on the cathode improves the power performance for the “sm” and the “t” units. Furthermore, it is shown that the design with the smaller internal diameter, performs better and is more stable through time.

Four multiple air–cathode microbial fuel cells (MFCs) were developed under the scope of using extracts from fermentable household food waste (FORBI) for the production of bioelectricity. The operation of the MFCs was assessed in batch mode, considering each cell individually. Τhe chemical oxygen demand (COD) efficiency was relatively high in all cases (>85% for all batch cycles) while the electricity yield was 20 mJ/gCOD/L of extract solution. The four units were then electrically connected as a stack, both in series and in parallel, and were operated continuously. Approximately 62% COD consumption was obtained in continuous stack operation operated in series and 67% when operated in parallel. The electricity yield of the stack was 2.6 mJ/gCOD/L of extract solution when operated continuously in series and 0.7 mJ/gCOD/L when operated continuously in parallel.

This study reports on the investigation of the digestate treatment using microbial fuel cell (MFC) technology. The effluents from a thermophilic and a mesophilic anaerobic digester, fed with fermentable household food waste (FORBI), were characterized and used as the feed in four air–cathode MFC units. The chemical oxygen demand (COD) removal ranged from 80% to 90% and was achieved within the first 24 h to 48 h of each cycle operation, although electricity was still produced for more than 190 h. The electrochemical characterization of the cells showed low internal resistances (10–50 Ω) of the units for both inlets. The maximum power output of the mesophilic fed cells (~ 0.24 mW) is lower in comparison with the respective power achieved from the thermophilic fed cells (~ 0.42 mW). The work demonstrated the potential of using MFC technology to further treat and exploit anaerobic digestates which are produced from FORBI.

A stack of two identical single chamber microbial fuel cells (MFCs) was assessed during using fermentable house hold extract as substrate. The design of the MFC units was based on the single chamber membrane-less technology using four cathode electrodes. The total power output was 492 mW either in series or parallel connection considering a total anolyte volume of 240 cm3. During continuous operation, the COD removal was 80% for each cell and for both operation modes (series and parallel). The electrochemical profiles provided significant information on the behaviour of the stack. During continuous operation, parallel connection is preferred over series connection, as it results to the same power output values, and COD removal but it provides lower internal resistances leading to more stable electrochemical performance behaviour.

A four air-cathode single chamber membrane-less microbial fuel cell (MFC) was developed and used to produce energy when fed with fermentable household waste extract (FORBI; 0.8 g COD/L). The employment of MnO2 as the cathode catalyst at a loading of 89 mg /cm2, the use of food residue biomass (FORBI) and the single chamber design provided a maximum power output of 3.2 mW in 120 ml anolyte volume under Open Circuit Voltage (OCV) conditions in three batch operation cycles. The COD removal was over 78% for all operation cycles. The total resistance of the proposed design of the MFC was in the range of 12.21-12.78 Ω, which is significantly lower than the internal resistance of dual chamber MFCs. Electrochemical Impedance Spectroscopy verified the values of the internal resistance and gave an insight in the electrochemical processes occurring in the MFC. Gradual development and stabilization of an active biofilm is recorded with FORBI as substrate, while the electrode charge transfer reaction remained stable during the batch cycles.
