The performance of our synthesized electrocatalyst are comparable to results that conducted by Champavert et al who fabricated a carbon felt modi ed with poly Ni(II) tetra sulfophthalocyanine as the cathode using acetate as organic source (Champavert et al 2015).

Mixed transition metal (Ni & Cu) oxides supported on graphene (NiO-CuO/G) electrocatalyst was fabricated and tested as an efficient and cost-effective cathode for oxygen reduction reaction (ORR) in microbial fuel cells (MFCs). The electrocatalytic activity and selectivity of the NiO-CuO/G for ORR were examined using linear sweep voltammetry measurements (LSV) on a rotating disc electrode (RDE) in pH-neutral electrolyte. In comparison with a benchmark platinum cathode, the NiO-CuO/G showed high selectivity towards the ORR. The analysis of Koutecky-Levich relationship suggests that the electrocatalyst follows the four-electron ORR pathway. NiO-CuO/G cathode in an air-cathode MFC exhibited a slightly lower power density 21.25 mWm− 2 compared to 50.4 mW m− 2 for Pt/C. Both scanning and transmission electron microscope analyses of anodic biofilm showed that a thick biofilm was successfully developed with a rod-like shape. Biochemical characterization of the communities showed that four genera named Escherichia coli (E-coli), Shewanella putrefaciens, Bacillus cereus and Bacillus Thuringiensis/mycoides, which belonging to GammaProteobacteria and Firmicutesphylathatwerethe most abundant bacteria in the anodic biofilm. Our results revealed that NiO-CuO/G cathode demonstrates an enhanced electrocatalytic activity toward ORR in a pH-neutral solution; thus, the newly developed mixed transition metal oxides electrocatalyst can replace other expensive Pt-based catalysts for MFC application.

“…22,24 Previous works with garden compost were mostly operated in a classical double chamber MFC (cDCMFC). 22,25 However, this classical system faces many limitations in large-scale applications and, as an alternative, the development of a single-chamber MFC with an air-breathing cathode system using garden compost is initiated. 26 Nonetheless, its power production is still very low.…”

“…The inoculum source was the garden compost leachate obtained by lixiviation, as explained in the previous work. 25 Garden compost and 60 mM potassium chloride solution (equivalent volume ratio of 1:1) were mixed and stirred for 24 h. The garden compost leachate was separated by rough filtration using a sieve. Sodium acetate was added to the garden compost leachate thus giving a final concentration of 20 mM.…”

The future of fuel cells that convert chemical energy to electricity relies mostly on the efficiency of oxygen reduction reaction (ORR) due to its sluggish kinetics. By effectively bypassing the use of organic surfactants, the postsynthesis steps for immobilization onto electrodes, catalytic ink preparation using binders, and the common problem of nanoparticles (NPs) detachment from the supports involved in traditional methodologies, we demonstrate a versatile electrodeposition method for growing anisotropic microstructures directly onto a three-dimensional (3D) carbon felt electrode, using platinum NPs as the elementary building blocks. The as-synthesized materials were extensively characterized by integrating methods of physical (thermogravimetric analysis, X-ray diffraction, scanning electron microscopy, inductively coupled plasma, and X-ray photoelectron spectroscopy) and electroanalytical (voltammetry, electrochemical impedance spectrometry) chemistry to examine the intricate relationship of material-to-performance and select the best-performing electrocatalyst to be applied in the model reaction of ORR for its practical integration into a microbial fuel cell (MFC). A tightly optimized procedure enables decorating an electrochemically activated carbon felt electrode by 40-60 nm ultrathin 3D-interconnected platinum nanoarrays leading to a hierarchical framework of ca. 500 nm. Half-cell reactions reveal that the highly rough metallic surface exhibits improved activity and stability toward ORR (E ∼ 1.1 V vs reversible hydrogen electrode, p(HO) < 0.1%) and the hydrogen evolution reaction (-10 mA cm for only 75 mV overpotential). Owing to its unique features, the developed material showed distinguished performance as an air-breathing cathode in a garden compost MFC, exhibiting better current and faster power generation than those of its equivalent classical double chamber. The enhanced performance of the material obtained herein is explained by the absence of any organic surfactants on the surface of the nanoarrays, the good metal-support interaction, particular morphology of the nanoarrays, and the reduced aggregation/detachment of particles. It promises a radical improvement in current surface reactions and paves a new way toward electrodes with regulated surface roughness, allowing for their successful application in heterogeneous catalysis.

“…The compartments are usually separated by a proton exchange membrane (PEM) [10]. The electrical efficiency of MFCs depends on multiple factors such as electrode material [11][12][13][14], cell configuration [15][16][17], microorganisms' cultures [18][19][20][21], and fuel characteristics such as organic load [22,23], conductivity and pH [24].…”

Towards the scale-up of bioelectrogenic technology: stacking microbial fuel cells to produce larger amounts of electricity

Experimental work carried out in this work has investigated the scale-up of microbial fuel cell (MFC) technology by studying the stacking of single microbial fuel cells, paying attention to the electric and hydraulic connections between each unit. To do this, the performance of three stacks (which were set up with different configurations) was studied for more than three months. The first stack (two hydraulically non-connected cells) was operated for 80 days without any electric connection between them, in order to determine the reproducibility of the performance of a single MFC, and then it was electrically connected in parallel for 20 days to determine if the electricity produced by each single cell was added when they were joined in the stack. The other two stacks (with five and ten cells, hydraulically connected) were connected electrically in series during the first 80 days and in parallel during the last 20 days. The results confirmed that connection in parallel allows higher current intensities and power to be obtained, and that the total electrode surface area attained with the stack is directly related to the production of electricity and to the removal of COD, although not in a linear way.
