 Even though the multimeter was connected the wrong way (+ on anode, - on cathode), we first had positive (and quite high) current and voltage value. Is this due to remanant charges from the PC battery ? Even though the multimeter was connected the wrong way (+ on anode, - on cathode), we first had positive (and quite high) current and voltage value.

 +==Conclusion==
 +
 +From both these expriments and those conducted in Bruxelles, we can conclude that the MFC behavior improves and stabilizes with time.
 +
 +As the "pile micrboienne marseillaise" increases its performance way quicker than the "Crate Design #2" It seems that a better mcirobial & nutrient source induces quicker results.
 +
 +Using newspaper or cardboard as a Proton Exchange Membrane seems fine.
 +
 +New long-term experiments should be conducted to test other parameters, including more broadly available electrode materials.
