can be used as feed for the anode respiring
bacteria that subsequently releases the electrons
from the oxidation process. The flow of electrons
from anode to cathode generates electricity
with circuit stabilisation that is achieved from
proton (H + ) flow via the PEM (proton exchange
membrane). In addition, the dissolved oxygen
(DO) profile has also been found to have a clear
positive correlation with the voltage output in the
MFC system. To compensate for the high cost
that arises from harvesting and post-proces
