In plant microbial fuel cells (p-MFCs) electrochemically active microbes present around the plant root convert rhizodeposits or the organic matter into electrons, protons, and CO 2 . This work covers the increasing trend in research with p-MFCs with their mechanism of operation. Different plant species and their selection criteria are also covered. Furthermore, the long-term evaluation of such systems with its cost effectiveness and commercial and environmental perspectives are also presented. A critical aspect for bioelectricity production is the photosynthetic pathway of the plant. Additionally, the microbial communities and reactor configurations employed across different capacities are also reviewed. The challenges with bioelectricity production and the opportunity for developing p-MFCs in conjunction with traditional MFCs are also covered. These electrogenic reactor systems harness bioelectricity without harvesting the plant and has the capacity to utilize this energy for remote power applications.

Microbial Fuel Cell (MFC) is a promising technology for harnessing energy from organic compounds. However, the low power generation of MFCs remains a significant challenge that hinders their commercial viability. In this study, we reported three distinct modifications to the stainless-steel mesh (SSM), carbon cloth, and carbon felt electrodes using carbon powder (CP), a mixture of CP and ferrum, and a blend of CP with sodium citrate and ethanol. The MFC equipped with an SSM and CP anode showed a notable power density of 1046.89 mW.m-2. In comparison, the bare SSM anode achieved a maximum power density of 145.8 mW m-2. Remarkably, the 3D-modified SSM with a CP anode (3D-SSM-CP) MFC exhibited a substantial breakthrough, attaining a maximum power density of 1417.07 mW m-2. This achievement signifies a significant advancement over the performance of the unaltered SSM anode, underscoring the effectiveness of our modification approach. Subsequently, the 3D-SSM-CP electrode was integrated into single-chamber MFCs, which were used to power a LoRaWAN IoT device through a power management system. The modification methods improved the MFC performance while involving low-cost and easy fabricating techniques. The results of this study are expected to contribute to improving MFC's performance, bringing them closer to becoming a practical source of renewable energy.

“…Depending on certain bio-waste with different concentrations, the produced output voltage value ranged from 0.423 V to 0.723 V [33]. In the year, 2017 the area of research expanded to include studying the effect of each: the number and material type of electrode and the addition of resistors of different values in parallel with the cell [34][35][36][37]. During 2018 and 2019, studying the operation of different MFCs showed constant output voltage ranging from 60-550 mV while operating the cell for about a week [38].…”

Microbial Fuel Cell (MFC) represents a promising approach for generating power inexpensively. Moreover, it is considered as an alternative green energy source. It could generate electrical energy by utilizing a wide range of organic substrates, as well as complex organic matter present in various environmental wastes depending on the bio-catalysis of microorganisms. However, the utilization of MFC in electronic applications is limited, due to its low output power density and output voltage. The present work aims to enhance the generated output voltage of a single MFC by applying DC-DC boost converter circuit. Before applying this circuit, a similar stacked series 6-MFCs are constructed for increasing its generated output voltage (on average 1.04V), where their produced output voltage reached about 6.24 V. In most electronic applications, the required voltage and current exceed these values. Hence, as a solution, a DC-DC boost converter circuit is recommended with an input voltage of 6 V based on the voltage harvested from the cascaded series 6-MFCs using a 6V/2A lead acid battery. In this work, the designed converter was operated in the discontinuous conduction mode (DCM) giving a variety of output voltage ranging from 15.8 V at load resistance (RL) of 220 Ω up to 21.2 V at RL of 620 Ω.
