 I am currently playing with parameters: sample source, design geometry, electrode materials, nature of the proton exchange membrane (PEM), water source... To understand better the drivers of electrical power delivered by these Quick & Dirty MFCs. I am currently playing with parameters: sample source, design geometry, electrode materials, nature of the proton exchange membrane (PEM), water source...

-So far, the peak power I measured was 0.5 mW [[michka:research:microbial_fuell_cells:Bruxelles2|during my experiments in Brussels]], which is still not sufficient.+So far, the peak power I measured was 0.5 mW [[michka:research:microbial_fuel_cells:Bruxelles2|during my experiments in Brussels]], which is still not sufficient.

-===Two containers + Air Pump Design===+I started this research by looking for existing quick & dirty designs online. I found two main categories of designs
  
-[[http://www.instructables.com/id/DIY-Microbial-Fuel-Cell-easy/|This 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.+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.
  
 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. 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.

-===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.+The **[[http://www.treehugger.com/slideshows/gadgets/make-microbial-fuel-cell/page/1/#slide-top| one-container 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.
