“…Other alternative technologies of renewable energy production base on anaerobic fermentation are the so-called Bio-Electrochemical Systems (BESs) (HernandezFernandez et al, 2015). Typical BES configuration uses micro-organisms to catalyze an oxidation and reduction reaction at an anodic and cathodic electrode, respectively (Hernández-Fernández et al, 2015). Oxidation of organic and inorganic electron donors occurs in the anode (Ter Heijne et al, 2006).…”

“…Responsible for the process are specific bacterial species, the so-called "exoelectrogens", mainly belonging to the gammaand delta-subgroups of Proteobacteria (Sciarria et al, 2013). The potential of BESs is enormous since this technology has important operational and functional advantages over the current technologies used for generating energy and valuable compounds from organic matter (Hernández-Fernández et al, 2015). Furthermore, BESs do not require a gas treatment because the off-gases of these devices are enriched in CO 2 and normally have no useful energy content.…”

Suitability of olive oil washing water as an electron donor in a feed batch operating bio-electrochemical system

et al. 2017

SUMMARY:Olive oil washing water derived from the two-phase manufacturing process was assessed as an electron donor in a bio-electrochemical system (BES) operating at 35 ºC. Start-up was carried out by using acetate as a substrate for the BES, reaching a potential of around +680 mV. After day 54, BES was fed with olive oil washing water. The degradation of olive oil washing water in the BES generated a maximum voltage potential of around +520 mV and a Chemical Oxygen Demand (COD) removal efficiency of 41%. However, subsequent loads produced a decrease in the COD removal, while current and power density diminished greatly. The deterioration of these parameters could be a consequence of the accumulation of recalcitrant or inhibitory compounds, such as phenols. These results demonstrated that the use of olive oil washing water as an electron donor in a BES is feasible, although it has to be further investigated in order to make it more suitable for a real application.

El agua de lavado del aceite de oliva procedente del proceso de elaboración en dos fases fue utilizada como donador de electrones en un Sistema Bioelectroquímico (BES) operado a 35ºC. Se realizó una etapa de arranque del sistema mediante alimentación con acetato, alcanzando un potencial de referencia de +680 mV. Tras 54 días, el sistema se alimentó con agua de lavado de aceite, generando un potencial máximo de +520 mV y una eliminación de materia del 41%, en demanda química de oxígeno. Sin embargo, cargas subsecuentes conllevaron una bajada en la eliminación de materia, mientras que la densidad de corriente y de potencia disminuyeron ostensiblemente. El empeoramiento de estos parámetros puede deberse a la acumulación de compuestos recalcitrantes o inhibidores, como fenoles. Por tanto, el uso del agua de lavado de aceite de oliva en un BES es factible, aunque es necesario llevar a cabo nuevas investigaciones que hagan más atractiva su aplicación a escala real.

“…As a consequence, the investigation on alternative Pt-free catalysts has been thorough [34,35]. The use of noble metals-free catalysts such as phthalocyanine (FePc), pyrolyzediron (II), and cobalt tetramethoxy-phenyl-porphyrin (CoTMPP) has been proposed as platinum-free cathode electrodes for MFCs [36][37][38]. Another alternative is the use of inorganic based catalysts, such as iron, cobalt, nickel, or manganese [39].…”

Abstract:A comparison between different carbon-based gas-diffusion air-breathing cathodes for microbial fuel cells (MFCs) is presented in this work. A micro-porous layer (MPL) based on carbon black (CB) and an activated carbon (AC) layer were used as catalysts and applied on different supporting materials, including carbon cloth (CC), carbon felt (CF), and stainless steel (SS) forming cathode electrodes for MFCs treating urine. Rotating ring disk electrode (RRDE) analyses were done on CB and AC to: (i) understand the kinetics of the carbonaceous catalysts; (ii) evaluate the hydrogen peroxide production; and (iii) estimate the electron transfer. CB and AC were then used to fabricate electrodes. Half-cell electrochemical analysis, as well as MFCs continuous power performance, have been monitored. Generally, the current generated was higher from the MFCs with AC electrodes compared to the MPL electrodes, showing an increase between 34% and 61% in power with the AC layer comparing to the MPL. When the MPL was used, the supporting material showed a slight effect in the power performance, being that the CF is more powerful than the CC and the SS. These differences also agree with the electrochemical analysis performed. However, the different supporting materials showed a bigger effect in the power density when the AC layer was used, being the SS the most efficient, with a power generation of 65.6 mW·m −2 , followed by the CC (54 mW·m −2 ) and the CF (44 mW·m −2 ).

“…They can relatively keep long-term durability. However, the most crucial issue for MGFCs is the low electronic conversion rate, and using noble metals significantly increases the cost of the device [15][16][17].…”

Abstract:Six different electron mediators were immobilized on the activated carbon (AC) anode and their effects on performance of a direct glucose alkaline fuel cell were explored. 2-hydroxy-1, 4-naphthoquinone (NQ), methyl viologen (MV), neutral red (NR), methylene blue (MB), 1, 5-dichloroanthraquinone (DA) and anthraquinone (AQ) were doped in activated carbon (AC), respectively, and pressed on nickel foam to fabricate the anodes. NQ shows comparable performance with MV, but with much lower cost and environmental impact. With NQ-AC anode, the fuel cell attained a peak power density of 16.10 Wm´2, peak current density of 48.09 Am´2, and open circuit voltage of 0.76 V under the condition of 1 M glucose, 3 M KOH, and ambient temperature. Polarization curve, EIS and Tafel measurements were also conducted to explore the mechanism of performance enhancement. The high performance is likely due to the enhanced charge transfer and more reactive sites provided on the anode.
