In the second column, “S” is for the single-air cathode MFC and “D” is for the dual-chamber MFC including the “H style” MFC. “-” means that it is not mentioned in the research. In the fourth column, “NO” represents membrane-free, and CEM represents cation exchange membrane. RE means the external resistance.
