Figure 9
Effect of external resistance on the cathodic, anodic, and cell potentials. Anodic and cathodic potentials are presented against a saturated Ag/AgCl electrode. The linear fit at high external resistances (region B) represents a region in which the external resistance controls the power. The linear fit at low external resistances (region A) represents a region in which the power is limited by kinetics, mass transfer, or internal resistance. Anode solution: 10 mL of cell culture medium; anode electrode: carbon felt modified with PLL (~10 cm2); cell density: cells/mL; cathode solution: 0.1 M potassium ferricyanide; cathode electrode: Carbon felt (~10 cm2); and reference electrodes: Ag/AgCl, sat. KCl.
