Scale Up of a Marine Sediment Microbial Fuel Cells Stack with a Floating Aerated Cathode Using a Circuit Storage Energy from Ultra-Low Power

In this study, it was proposed to design, build, analyze and evaluate a stack of 9 Sediment Microbial Fuel Cells (SMFC) with a depth in the sediment of 10 cm and separation between anode and cathode of 100 cm, using floating cathodes aerated with saturated oxygen, sediments and seawater were collected from the Campeche bay (Mexico). Maximum power density and current density were 101.28 mW/m2 and 899.51 mA/m2 respectively, and organic matter removal was 9.25%, obtaining aromatic structures. Using a circuit storage energy from ultra-low power. Our findings revealed that the implementations of SMFC stack proposal could be a candidate for real scale.
