Microbial fuel cell with garbage treatment

抄録

This study intends to develop a new application of MFC (Microbial Fuel Cells) to microbial garbage treatment; i.e., to perform decomposition of organic compounds in garbage and generation of electricity simultaneously. At first, the condition of electricity generation using a model substrate was established, and then the optimum condition for the two purposes stated above was clarified. For instance, active carbon is indispensable as a catalyst for the positive electrode. Since the amount of electricity generated by this system is very small, another suitable use of this system was pursued. One possible application was suggested: use as a diagnostic sensor for garbage treatment systems. Electricity generation occurs only when the system becomes anaerobic, which is bad for decomposition. No electricity was detected when decomposition of garbage was achieved in good, aerobic conditions.
