electrode :

May I know Why reasent studies are using Carbon materials on both Electrode? How could it be possible to generate Electricity if the anode and cathode have no potential difference since they are using the materials (carbon)

voltage reading:

I have constructed a two chambered type MFC. I tried to run it and record the voltage reading. I got an average reading of 35 mV in  6 hrs. Is this acceptable?

please help me

Hello! 
You should be able to record a potential difference if you put a load (e.g electrical resistor) between the two electrodes. The potentiel does not depend on the electrode material itself but on the electrochemical reaction occuring on their surface.  
anyway 35mV looks quite low... 
 
Best regards
