Abstract: Microbial fuel cell (MFC) technology is known for its ability to generate electricity directly from the oxidation of biochemicals via the help of electroactive bacteria (EAB). However, the real-life application of MFC was not yet realized due to the high-cost of cell material and numerous operational difficulties. In this thesis, we attempted to improve MFC’s practicality through three distinctive projects. The first study acetic acid was found to provide optimal long-term performance in “zero-electrolyte-discharge” air-cathode MFCs among the selected substrates. The second study showed that graphite-like carbon (GLC) coating drastically improved the performance of stainless steel as MFC anode material. The resulting performance was comparable to carbon base materials such as graphite and carbon cloth. In the third study showed improved long-term performance and record-breaking salt removal rate (99.9%) of microbial desalination cell was achieved by using bicarbonate buffer as electrolyte and implementing external electrolyte reservoirs.
