pH,. To determine the effect of ,pH,, we examined power generation and CE using a medium containing 0.06 M NaHCO 3, 0.05 M KCl, and 0.007 M Fe2+. The ,pH, was varied from 4 to 7.5 by adding HCl or NaOH. An optimal power production of 290 mW/m2 was achieved at a ,pH, of 6.3, with power decreasing to <250 at ,pH, ) 5 and to 185 mW/m2 at ,pH, ) 7.5 (Figure 6).
