초록

Ferricyanide를 환원제로 사용하는 이형반응기 미생물연료전지 시스템에서 전류밀도, 전력밀도, 쿨롱효율 등의 전기적 특성에 미치는 외부저항의 영향을 규명하고자 하였다. 음극반응기에 미생물을 접종하고 일정한 시간이 경과하면 안정적인 전기가 생산되었으며 $50{\Omega}$의 외부저항에서 0.13~0.16 V 범위의 전압이 발생되었다. 외부저항이 증가함에 따라 전류밀도는 감소하였으며 전력밀도는 일정한 값까지는 급격하게 증가하다가 서서히 감소하는 것으로 나타났다. 외부저항을 단계적으로 감소시키는 반복실험을 수행한 결과, 일정한 범위의 전류밀도까지는 측정값들의 편차가 크지 않았으나 높은 전류밀도 영역에서는 기질소모로 발생하는 농도손실의 영향으로 측정값의 변동성이 매우 크게 나타났다. 전력밀도 및 쿨롱효율은 MFC 시스템의 내부저항($134{\Omega}$)과 가까운 $100{\Omega}$의 외부저항에서 각각 $175.8mW/m^2$과 46.1%의 최대값을 가지는 것으로 나타났다.

The Effects of external resistance on electrical properties such as current density, power density and coulombic efficiency were investigated in two-chamber type MFCs using a ferricyanide as reducing agent. A stable electricity was produced when a constant time elapsed after innoculation of mixed cultures into the anode compartment; voltages from 0.13 to 0.16 V was measured at $50{\Omega}$ of external resistance. When the external resistance was increased, the current density decreased and the power density rapidly increased and then slowly decreased. Big variation of electrical properties was observed in high-current density region due to the concentration loss related with substrate consumption in repeated experiments changing the external resistance. The maximum power density ($175.8mW/m^2$) and coulombic efficiency (46.1%) were obtained at $100{\Omega}$ of the external resistance which is nearest with the internal resistance ($134{\Omega}$) of MFC system.
