[Influence of environmental factors on electricity production by microbial fuel cell inoculation Shewanella baltica].
The influences of the anodic substance, concentration, pH and temperature on the electricity production by MFCs were discussed. The lactic sodium was better than acetic sodium or glucose. The power density of MFC and the concentration of lactic sodium were well filled with Monod model. The power density was 1236 mW/m2 when the pH of anodic chamber was 8. The power density of MFC increased with the pH increasing from 6 to 8, which was due to the anodic internal resistance. The power density was 1 197 mW/m2 when the temperature was 50 degrees C. The power density of MFC changed with temperature because the anodic resistance decreased with the temperature increasing. While the temperature changed from 20 degrees C to 50 degrees C, the current density and the temperature were well filled in Arrhenius equation.
