1.1. Definition and basic principle of MFC
When microbial oxidizes organic compounds, released electrons produce energy in the form of ATP, passing a series of electron pathway and electrons which pass the pathway reduce TEA(terminal electron acceptor). In this manner, metabolism of microbial completes. Generally, that TEA accepts the electrons occurs in inside of cell but some microbials can transport electrons to metal oxide as a TEA under the presence of a transporting substance called Mediator. In the MFC, mediator has a role in transporting electrons to the anode. And the microbials which can transport electrons to the outside by the mediator are called exoelectrogen. Since they are anaerobic bacteria in most cases, anode at which microbial is located is called anaerobic digester.
Exoelectrogen, anaerobic digester and mechanism producing electrons by oxidizing organic compounds, we call them MFC all of a lump.

Figure 1.1. Principle of MFC

As we can see in above figure, there is a membrane which only allows the hydrogen to penetrate it.
