Abstract
In the present work, a dual-chamber microbial fuel cell (MFC) was constructed with aeration tank sludge as an inoculum, carbon felt as an anode and stainless steel mesh without any modification as a cathode. The influence of the cathode size was investigated in terms of voltage output, power generation and electrochemical impedance. The long-term durability of the stainless steel mesh cathode was also evaluated. Results showed that the stainless steel mesh exhibited satisfactory long-term durability as MFC cathode. When the stainless steel mesh size was 2 × 2 cm2, the maximum output voltage, power density, the internal resistance and the polarization resistance were 0.411 V, 0.303 W•m-2, 841 Ω and 80 Ω, respectively. Increasing the cathode size to 2 × 4 cm2, the maximum output voltage could reach 0.499 V, and the internal resistance reduced to 793 Ω. These studies demonstrated that the stainless steel mesh was suitable for MFC cathode because of its durability and low price.
