Electricity generation with the use of microbial electrochemical systems

The renewable energy demand is growing with time to achieve sustainability and use of lower fossil fuels. Electrochemical systems have the potential to generate electricity, which is sustainable and environmentally benign. This chapter focuses on the generation of electricity with the use of microbial electrochemical systems. The chapter covers the introduction of microbial electrochemical systems Introduction to microbial electrochemical systems, electrogenic organisms, typical applications for microbial electrogenesis, principles of microbial electrochemical systems (fuel cells and electrolysis cells), microbial fuel cell performance (operation parameters), microbial fuel cell design (architectures and reported efficiency), microbial fuel cell scaling-up, challenges to improve microbial fuel cell performance at real-life scale, manufacturing, cost, carbon footprint and comparison with clean electricity technologies and perspectives of microbial fuel cells.
