  • Title: Power overshoot in two-chambered microbial fuel cell (MFC).
    Author: Nien PC, Lee CY, Ho KC, Adav SS, Liu L, Wang A, Ren N, Lee DJ.
    Journal: Bioresour Technol; 2011 Apr; 102(7):4742-6. PubMed ID: 21295969.
    Abstract:
    A two-chamber microbial fuel cell was started using iron-reducing strains as inoculum and acetate as carbon sources. The tested microbial fuel cell had an open-circuit voltage of 0.67 V, and reached 1045 mA m(-2) and a power density of 486 mW m(-2) at 0.46 V before power overshoot occurred. Anodic reactions were identified as the rate-determining steps. Stirring the anolyte insignificantly increased cell performance, suggesting a minimal external mass transfer resistance from the anolyte to the anodic biofilm. Data regression analysis indicates that charge transfer resistance at the biofilm-anode junction was negligible. The order of magnitude estimation of electrical conductance indicates that electron transfer resistance had an insignificant effect on microbial fuel cell performance. Resistance in electrogens for substrate utilization is proposed to induce microbial fuel cell power overshoot.
