In this study, ACMFC1 and ACMFC2 with different electrode configuration were compared to examine power density and electron recovery from glucose. The results showed that ACMFC1 generated a maximum power density of 3 070mW/m3 with internal resistance of 302.141 and anode potential of -323mV; while maximum power density of 9 800mW/m3 for ACMFC2 was obtained with internal resistance of 107.79omega and anode potential of -442mV. ACMFC2 could sustain generating electricity for nearly 220 h (ERE of 30.1%), comparing with ACMFC1 of less than 50 h (ERE of 9.78%) under batch operation. Therefore, an improved design for electrode configuration of ACMFC can be performed to generate higher power with low internal resistance, meanwhile, achieve increasing electron recovery simultaneously. %K air-cathode microbial fuel cell(ACMFC) %K electrode configuration %K power density %K electron recovery efficiency
