An Introduction to Sediment Microbial Fuel Cells. What is a Fuel Cell?. A fuel cell is a device that generates electricity through a chemical reaction. It is similar to a battery, but unlike a battery the chemicals can be continuously supplied. What is electricity?.
electricity through a chemical reaction.
the chemicals can be continuously supplied
Tube filled with electrolyte solution
A solution that can carry ions between the anodic and cathodic chambers.
Two parts to the reaction:
+ H2O CO2 + H+ + electrons
Oxygen + H+ + electrons H2O
C2H4O2 + 2H2O 2CO2 + 4H+ + 4e-
C6H12O6 + 6H2O 6CO2 + 24H+ + 24e-
4O2 + 4H+ + 4e- 4H2O
6O2 + 24H+ + 24e- 12H2O
