FIG. 2.

Current-voltage and current-power (watts = amperes × volts) relationships for fuel cells containing G. sulfurreducens shown in Fig. 1. Open symbols represent the current produced from the oxidation of acetate in a fuel cell after the initial growth of cells in the electrode chamber. Closed symbols represent current produced from the oxidation of acetate in the fuel cell after the medium was replaced the second time.
