Microbial fuel cells: An enhanced technology for more sustainability

Abstract

Microbial fuel cells (MFCs) are non-traditional systems that produce electric power through the metabolic activity of microorganisms, particularly in the treatment of waste water. They oxidise organic substances, removing the polluting matter as well as producing pure water and electric energy. MFCs are an alternative to traditional treatment systems energy-saving and sustainable and provide a way to come out from an increasing outlay of operating expenses in the present day. In addition, there is no gas of greenhouse imaging. Further work has to be accomplished before MFCs become a commercial reality. In this paper the structure, main problems and working principle are examined and also the related material mechanics for the MFCs is dealt with, and an analysis is made concerning the projects for their direction sewage treatment by new advance in this year's technology, and with that also their problems met with.
