Feasibility study of stacking operations on microbial fuel cell

Bioelectricity generation from biomass by using bacteria in a fuel cell reactor is becoming popular since the increasing demand and price of fossil fuels. Microbial fuel cells (MFCs) can be used to generate electricity from various forms of biodegradable organic matter but with limited voltage produ...
