Abstract

Microbial fuel cells (MFCs) are a renewable energy technology. However, low power output remains the primary constraint in their commercialization. We have previously shown that MFC-microbial electrolysis cell (MEC) coupling based on the principle of electric field superposition can improve the power output of MFC. In this study, a multiphysics field simulation model was developed based on the MFC-MEC. We further evaluated the effect of a microelectric field (MF) on liquid-phase mass transfer (LPMT). The results showed that the total electromigration and diffusion fluxes of the MFC-MEC with shared anode (SA-MFC) were approximately 2–5-fold higher compared to the control, suggesting that MF improved LPMT. Notably, electromigration fluxes of SA-MFC accounted for 51.1 % of LPMT fluxes, which were higher than those in the control group (31.7 %), indicating that electromigration dominated the electrode region. The LPMT exhibited a synergistic relationship with the internal resistance and reaction rate, and the enhancement of the LPMT was beneficial for reducing the internal resistance and accelerating the reaction rate, which effectively improved the performance of the MFC. Hence, the enhancement of the LPMT is a critical step in improving the performance of MFC and provides new insights for further improving the performance of MFC.
