Abstract
In this study, a novel type of swirler channel was implemented at the inlet of the anode chamber of dual-chamber batch mode MFC, and comparison was done between with and without swirler. To explore the effect of the swirler in detail, four different flow rates (40 mL/min, 20 mL/min, 10 mL/min, and that 5 mL/min) were selected, and their performance was compared. The experimental results showed the swirler system has a maximum current density of 4424.3 mA/m(2), a power density of 775 mW/m(2), and reduced the internal resistance by 60% at a 20 mL/min flow rate when compared with `without swirler' system (2686 mA/m(2); 442 mW/m(2) @ 20 mL/min) because of uniform distribution of substrate and enhanced the mixing in the anode chamber. Our results demonstrated that the swirler channel will have a prominent effect on the performance and can be effectively used for applications and in future researches.
