초록

A submerged air-cathode microbial fuel cell (SA-MFC) was evaluated according to cathode materials and anode-cathode surface area ratios (A/C ratio). When a C-cathode (capacity deionization electrode) with catalyst (CuPC+FePC), a C-cathode without catalyst and a M-cathode (CNT-base MFC electrode) with (CuPC+FePC) were applied to SA-MFC, the maximum power densities were 1.5 W/㎥, 5.2 W/㎥ and 5.5 W/㎥ respectively. A C-cathode with catalyst showed the similar maximum power density to a M-cathode with catalyst and is inexpensive compare to a M-cathode. Therefore, it is thought to be that a C-cathode with catalyst can be one of the cost effective cathodes for the MFC. When A/C ratios were changed from 1:1 to 1:2, 1:4 and 1:8, the maximum power densities of each surface area ratio were 1.1 W/㎥, 1.7 W/㎥, 2.3 W/㎥ and 3.5 W/㎥ respectively. As the A/C ratio increased, the maximum power density was also increased. It is thought to be that the cathode surface area is major limiting factor for energy generation in a SA-MFC.
