Increasing amps on an MFC

[deleted-452012]

First of all hello to everyone reading this and trying to help me.We have been invited to our national science fair recently our project is about MFC systems and we have been trying to increase our voltage from the beginnig we did not realise we need amp as well.So we have focused on voltage and we did increase it with connectinng MFC systems together.We tied 18 MFCs together and got 10 volts from it.Our reading for each MFC was between 0.4 volts and 0.9 volts.Homever we realised we need amps to make little engines and LEDs work.We got 6 volts and 0.2 mA s from 12 MFCs connected serially.But i must not that our MFCs werent using Carbon based materials for anode catode.We could not find them in my country(Turkey).Reistance was around 5 to 6 ohms as well.is there a way to increase or amperes around 33 mA and our volt to around 4.25 for us to make our little engine or a led work?


Sorry for my bad english.
