Power production characteristics of binary particles pulsed anaerobic fluidized bed microbial fuel cell
A novel binary particulate pulsating anaerobic fluidized bed microbial fuel cell (BPFB-MFC) was designed and constructed in order to improve the efficiency of low-grade energy conversion in sewage. The effects of pulsed liquid flow rate and bed filling rate on the electricity production performance and effluent treatment characteristics of the BPFB-MFC were investigated experimentally. The results showed that when the pulsed liquid flow was u=1.95sin(π/3)t cm·s−1 and when the bed materials in the anode chamber consisted of 10 % bed height activated carbon particles and 10 % bed height ceramic particles, the highest voltage produced was 519.7 mV, the highest power density was 587.5 mW·m−2, and the lowest internal resistance was 171.2Ω, which was the optimal experimental working condition. It was found that the electricity production performance and effluent treatment efficiency of the mixed particles system were better than those of a system with single particles. This work held promise of promoting the industrialization of MFC.
