“…The power density (Pd) of P-MFCs was calculated using equation (2). In these equations, V is the potential (voltage), I is the current, and S is the geometric surface area of the electrode (Erensoy and Çek 2021;Erensoy et al 2022;Walter et al 2022;Mashkour et al 2020).…”

“…The result of this process enables the production of clean, green, and renewable electricity (Çek and Erensoy 2020;Apollon 2023). In order for the microbial fuel cell to produce more green electricity, moss (Çek et al2022; Çek 2016) cow manure (Çek et al 2022), soil (Tang et al 2023), sediment (Ak et al 2020) and peat (Erensoy et al 2022) materials have also been investigated as organic material sources. Although each of these materials has their strengths and weaknesses, their great benefits are that they are natural materials.…”

Plant-based plant microbial fuel cells are introduced as devices that directly convert solar energy into electrical energy through photosynthesis reactions. Plant microbial fuel cells, which are a renewable and sustainable energy source, produce bioelectricity at different levels depending on plant species and characteristics. In this paper, a plant microbial fuel cell was manufactured by planting Aloe vera in natural plant soil and placing graphite electrodes, then it was operated by giving pure water. Thus, an Aloe vera based plant-microbial fuel cell was manufactured and open circuit potential, linear scanning voltammetry and electrochemical impedance spectroscopy tests were performed. The peak open-circuit potential generated by the aloe vera-based plant microbial fuel cell was 288 mV, and the peak value of power density reached levels of 200 W/m2. The high activation resistance and ohmic resistance of aloe vera-based plant microbial fuel cell triggered total internal resistance, causing it to show internal resistance at levels of 10 kiloohms. The aloe vera-based system demonstrates promising potential for electricity generation, as evidenced by its peak open-circuit potential. However, the high activation resistance and ohmic resistance leading to a total internal resistance of 10 kiloohms highlight areas for improvement to enhance its efficiency and practicality for widespread use. Further research and development are needed to address these challenges and unlock the full capabilities of aloe vera-based P-MFCs.

“…OCV is the potential difference between the anode and cathode electrodes, and does not depend on the presence of resistance. OCV measurement is performed to evaluate the maximum voltage of MFC (Erensoy et al, 2022), as there are no current and losses. Figure 4 (a) shows the curve of OCV value versus time for each MFC biocatalyst by five electroactive microbes isolated from the sediments of Waduk Saguling, and (b) the highest OCV value attained by these five bacteria.…”

The application of microbial fuel cells is still facing some challenges due to its low power output and high internal resistance. It is desirable to obtain a stable and consistent power output from an MFC to support practical real-world applications. Five electroactive bacteria (isolate LGf1, LGf11, LGf15, LGf20, and LGf22) isolated from the sediment of Waduk Saguling were exploited as the potential anodic biocatalyst for MFC, and the performance of these MFCs were studied in terms of voltage generation (open and close circuit), power density and the losses (polarization technique), and efficiencies (coulombic and energy). MFC biocatalyst by isolate LGf11 performed the best electrochemical performances, including highest OCV (open circuit voltage) value (804 mV) and power output (0.043 W/m2), lowest ohmic resistance (475 Ω), and highest coulombic efficiency (75.79%) and energy efficiency (88.36%) among all anodic biocatalysts. Nevertheless, all the five isolates were potential to be exploited as active biocatalyst for MFC due to their high OCV values and the stability of voltage generations, both in open circuit and close circuit mode. The development of system configuration and the use of more suitable substrate for different electroactive microbes in order to harvest more power output was recommended for further study. Utilization of these potential microbes for other applications in MFC (such as wastewater treatment etc.) was also suggested for further research.

“…Therefore, the technology of microbial fuel cells (MFCs) is presented as a promising technology to provide an excellent alternative to society by generating electricity, using its organic waste as fuel. These cells consist of two chambers (anodic and cathodic) which are almost always linked by a proton exchange membrane and contain electrodes inside, which are linked by an external circuit (Ramya and Kumar, 2022;Erensoy et al, 2022;De La Cruz et al, 2021). This technology is based on the conversion of the chemical energy present in the organic waste into electrical energy, where the oxidation occurs in the anodic chamber and the reduction in the cathodic chamber, the electrons produced in the oxidation are captured by the anodic electron, and travel by the external circuit to the cathodic electrode, which generates a flow of electrons producing the electric current (Sravan et al, 2021;Tan et al, 2021;Jatoi et al,2011).…”

A large amount of fruit waste is being a great environmental and social problem due to a lack of adequate storage. Among the most abundant waste is papaya, due to its high consumption in various varieties. These wastes can generate bioelectricity through organic waste, being an important parameter the pH. In this research, low-cost laboratory-scale microbial fuel cells were fabricated, using papaya waste as fuel at different pH (4, 5.73, 7, and 9) to obtain the optimum operating pH. It was possible to observe the maximum values of electric current and voltage of 17.97 mA and 1.02 V on days 16 and 14, in the cell with pH 7; while the cell with pH was the one that showed the lowest values. The electrical conductivity values increased from the first day, observing a maximum peak of 172.50 mS/cm for the cell with pH 7. However, the internal resistance values were low, the maximum value being for the cell with pH 4 (234.61 ± 34 Ω) and the minimum for the cell with pH 7 (46.543 ± 3.6 Ω). In the same way, the maximum power density was for the cell with pH 7 of approximately 645.74 ± 33.64 mW/cm2 and a current density of 5.42 A/cm2.
