 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 ?
+==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.
