Abstract: Novel sources for a renewable energy supply have become a global challenge. Wetland-microbial fuel cells (WL-MFCs) are being considered as a high potential technology to combat this issue. The use of the plant-microbial interaction between Echinodorus cordifolius and Bacillus thuringiensis can promote long-term WL-MFC system operation. This study aims to present a suitable design for the application of an E. cordifolius-MFC inoculated with B. thuringiensis. The results show that the serial connection of two small WL-MFCs can increase the electrical density compared with a single WL-MFC system. Interestingly, the two connected small WL-MFCs can also produce better electrical density than a large WL-MFC cell. For low electric production in the large WL-MFC cell, the result can be explained by the high oxygen concentration in the anode part of the system, which is associated with a low oxygen concentration (anaerobic conditions). These two connected small WL-MFCs can generate an electrical supply of ~ 50–60 mW/m2 for longer than 160 days. Although during the first 100–120 days of operation, the WL-MFC containing soil and B. thuringiensis can generate higher electric support than the WL-MFC containing soil, E. cordifolius and B. thuringiensis, with the plant, the WL-MFC can be operated for longer than WL-MFC without the plant. These results suggest that the application of WL-MFCs in a suitable design and operation can be good potential sources for a renewable energy supply.
