In methane (CH<sub>4</sub>) fermentation, approximately 60% CH<sub>4</sub> and 40% carbon dioxide (CO<sub>2</sub>) are produced. In recent years, <i>electromethanogenesis</i>, an electrochemical approach to converting CO<sub>2</sub> into CH<sub>4</sub>, has gained attention. This study aims to investigate the feasibility of directly using solar cells as an external power supply. In addition, the effect of electricity supply patterns, such as supplying electricity during the daytime and stopping at night, on CH<sub>4</sub> production was examined. Experimental results revealed that the application of electricity led to the conversion of CO<sub>2</sub> into CH<sub>4</sub>. Moreover, intermittent power supply alleviated the impact of electricity on the amount of methane produced. These findings suggest that solar cells can be directly used as an external power source for electromethanogenesis. On the other hand, it was also found that an increase in pH and an excessive drop in cathode potential associated with electricity supply may limit the activity of methanogenic microorganisms.

To achieve a decarbonized society, energy production using biomass is essential. Focusing on underutilized food waste, we have been working toward the development of a steelmaking slag–sediment microbial fuel cell (SS-SMFC) that utilizes this waste. In this study, aiming at practical application, the effect of the cathode-to-anode surface area ratio on power generation performance was investigated using a developed two-chamber SS-SMFC system. Experimental results showed that increasing the surface area ratio from 0.25 to 2 led to increases in maximum power, limit current, and stable current. However, when the ratio exceeded 2, no significant changes in these performance indicators were observed, suggesting a shortage of electrons necessary for reactions at the cathode. These findings indicate that the optimal cathode-to-anode surface area ratio for this system is 2.

In recent years, phosphate recovery using microbial fuel cells (MFCs) has attracted increasing attention. However, conventional MFCs often rely on expensive ion-exchange membranes, which hinder their practical application. To address this limitation, we focused on sediment microbial fuel cells (SMFCs), which do not require such membranes. We hypothesized that the phosphate removal efficiency of SMFCs could be improved by connecting them in series with a solar cell (SC). Therefore, in this study, we evaluated the phosphate removal performance of an SMFC connected in series with a 1.5 V SC (SC-SMFC). Experimental results demonstrated that the SC-SMFC increased current density by approximately 4.5 times and improved phosphate removal efficiency by 1.6 times after 7 days, compared to a conventional SMFC. Moreover, the effect of the no electrical current during nighttime on phosphate removal was found to be minimal. Consistent with previous studies, the pH in SC-SMFCs reached around 9, promoting phosphate precipitation through calcium ion fixation.
