| Outline of Final Research Achievements |
In this study, to develop a new metal anode for more increased electricity generation, 14 different metals (Al, Ti, Fe, Ni, Cu, Zn, Zr, Nb, Mo, Ag, In, Sn, Ta, and W) and 31 of their oxidized forms were comprehensively tested. The untreated Mo and electrochemically oxidized Mo anodes showed the highest average of maximum power densities in the screening test, followed by flame-oxidized (FO)-W, FO-Fe, FO-Mo, and Sn-based anodes. The power output of FO-Fe was almost the same as that of FO-SS anode. A high maximum power density (1,296 mW/m2) was achieved using the untreated Mo anode in the microbial fuel cells (MFCs). The Mo anode continued to produce current without detectable corrosion until the end of operation (350 d). Geobacter was abundant in biofilm formed on the Mo anode, implying that the potential involvement of the bacteria in the Mo cycle on Earth.
