 I started this research by looking for existing quick & dirty designs online. I found two main categories of designs
-===Two containers + Air Pump Design===
+The **[[http://www.instructables.com/id/DIY-Microbial-Fuel-Cell-easy/|two-container + air pump design]]** is made of two containers, bridged together with a salt bridge (rope dipped in saturated salted water, wrapped in insulating tape), one with pond sludge, another with clear water.
-[[http://www.instructables.com/id/DIY-Microbial-Fuel-Cell-easy/|This **two-container + air pump** design]] is made of two containers, bridged together with a salt bridge (rope dipped in saturated salted water, wrapped in insulating tape), one with pond sludge, another with clear water.
 An airpump feeds clean water with oxygen for the reduction reaction: protons coming from sludge by the salt bridge, together with electrons coming from sludge by the wires, recombine with oxygen to make water. The airpump allows high current to be produced.
-Performances: 6V peaks, 200+ mA with airpump, 170 mA without.
+Performances: 6V peaks, 200+ mV with airpump, 170 mV without.
-===One container Design===
-[[http://www.treehugger.com/slideshows/gadgets/make-microbial-fuel-cell/page/1/#slide-top|This design]] is made from one container, sludge at the bottom, smart gel proton exchanger on top of it, and clean water on the very top. No air pump, but lower performances. Something like charcoal is used as an electrode material.
