Effect of Different Mediator Concentrations on Power Generation in MFC Using Ti‐TiO_2 Electrode

並列摘要


In this study, performance of MFC using three different mediators was investigated in terms of power density and internal resistance. Methylene blue (MB), neutral red (NR) and 2‐hydroxy‐1,4‐naphthoquinone (HNQ)mediators were used to increase power generation in MFC with the mediator concentrations of 50, 100, 200, 300 and 400 μM. The maximum power densities were recorded as 36, 31 and 18.7 mW/m^2withthe mediators of MB, NR and HNQ corresponding optimal mediator concentrations of 300, 200 and 50 μM, respectively. Further, it was observed that internal resistance changed with mediator concentration.
