  7. Abstract:
  8. A Microbial fuel cell is a Bioreactor in which chemical bands are broken and their energy convert to electricity by bio-catalysts such as microorganisms and enzymes. Depletion of energy resources encouraged researchers to investigate microbial fuel cell as a power bio-resource. MFCs produce electricity or hydrogen without any net carbon emission. Nowadays, real applications of microbial fuel cells are limited because their power density level is very low (about 1000 mW/m2). Many research projects are running to modify MFCs operation and optimize its costs. The most important application of MFCs is electricity production, hydrogen production, waste water treatment and BOD5 biosensor. In this project, a review of MFCs' principles, configurations, structures, components, operations, thermodynamics and calculations is presented in first two chapters. Moreover in experimental section a two chamber microbial fuel cell was constructed and investigated by glucose as a substrate. Subsequently it was used for treatment of waste water contains ethylene glycol. In this system power density, optimum resistance, maximum of open circuit voltage, internal resistance and columbic efficiency were calculated.
