| Title | Influence of the set anode potential on the performance and internal energy losses of a methane-producing microbial electrolysis cell. |
| Abstract | The effect of the set anode potential (between+200mVand-200mVvs. SHE, standard hydrogen electrode) on the performance and distribution of internal potential losses has been analyzed in a continuous-flow methaneproducing microbial electrolysis cell (MEC). Both acetate removal rate (at the anode) andmethane generation rate (at the cathode) were higher (1 gCOD/L day and 0.30m3/m3 day, respectively)when the anode potentialwas controlled at+200mV. However, both the yields of acetate conversion into current and current conversion intomethanewere very high (72-90%) under all the tested conditions.Moreover, the sum of internal potential losses decreased from 1.46 V to 0.69 V as the anode potential was decreased from +200 mV to -200 mV, with cathode overpotentials always representing the main potential losses. This was likely to be due to the high energy barrierwhich has to be overcome in order to activate the cathode reaction. Finally, the energy efficiency correspondingly increased reaching 120% when the anode was controlled at -200 mV. |
