Abstract
The effects of operating temperature and electrode gap distance on electricity generation were investigated in two-chamber type MFCs. Voltages across the external resistor (100 ) were Ω enhanced approximately 1.4 times by the increase of operating temperature from 30 to 34 . ℃ ℃ The open circuit voltages (OCVs) were increased by the increase of temperature and the maximum power of MFC was obtained at higher current condition by increasing temperature and reducing electrode gap distance. The maximum power densities were enhanced from 1.9 to 2.4 times according to the experimented electrode gap distances by increasing temperature of 4 . ℃ The electricity generation was increased with the decrease of electrode gap distance. The effects of operating temperature and electrode gap distance were closely connected with the internal resistance of MFC system. That is, the increase of temperature and decrease of electrode gap distance reduced the internal resistance of MFC, resulting in the enhancement of electricity generation of MFC.
