Performance of electrical energy monitoring data acquisition system for plant-based microbial fuel cell

Plant microbial fuel cell (Plant-MFC) is an emerging technology that uses the metabolic activity of electrochemically active bacteria (EABs) to continue production bioelectricity. Since its invention and date, great efforts have been made for application both in real-time large-scale. However, construction platforms or systems automatic voltage monitoring has insufficiently studied. Therefore, this study aimed develop data acquisition system, which was coupled with ATMEGA2560 connected a personal computer. Before system operation started it calibrated obtain accurate data. During experiment, power generation performance two types reactors i.e. (i) Plant-MFC (ii) control (C-MFC), evaluated 15 days. The planted herbaceous perennial plant (Stevia rebaudiana), electrode placed close roots at depth 20 cm. results indicated Plant-MFC, more effective achieved higher bioelectricity than C-MFC. maximum reached 850 mV (0.85 V), whereas C-MFC 762 (0.772 V). Furthermore, same reactor demonstrated 66 mW m¯2 on 10 min polarization, while density equal 13.64 m¯2. S.rebaudiana showed alternative generation. In addition, suitable obtaining real-time. studies are recommended enhance type system.
