Abstract
This study presents the experimental investigation of the microfluidic microbial fuel cell – microbial electrolysis cell coupled system as a bioenergy generator to produce biohydrogen without any external power supply. The effect of microbial fuel cells number (to provide the required potential for microbial electrolysis cell), the type of substrate and its concentration were assessed. The maximum produced hydrogen of 25, 33 and 50 ppm were obtained in flow rate of 200 μl h-1 and glucose concentration of 200 mg l-1 in 1, 2 and 3 stack MFCs, respectively. For urea solution, by combination of 1, 2 and 3 stack MFCs in the flow rate of 200 μl h-1 and the concentration of 800 mg l-1, the maximum...

Abstract
Microbial Electrolysis is a new method for producing Biohydrogen from oxidation of organic materials by microorganisms. Generally, this process is depended on two different kinds of energy source containing Organic Material Oxidation by bacteria and Electricity. In this specific study, landfill leachate, extracted from ARADKOOH Tehran Iran was used as a carbon source and effective parameters in Microbial Electrolysis Cell were scrutinized for increasing the hydrogen production and efficiency of COD removal in wastewater. Two H-type rectors with 300 ml of volume in each side were used during the experiments. Various amount of voltages started with 0.4 (V), were tested in the system and it was...
Theoretical Investigation of Coupled Microbial Electrochemical Cells in Micro-Sized Systems and Assessment of Biohydrogen Generation

Abstract
Due to the importance of hydrogen production for its applications in therapy, this research reports the fabrication of a coupled microfluidic microbial electrochemical cell, including microfluidic microbial fuel cells (MFCs) and a microfluidic microbial electrolysis cell (MEC) series in order to perform it as a selfpowered bioenergy generator to produce biohydrogen with no need for an external power source. The designed went goes through a validation process that relied on experimental results of a coupled system in glucose degradation. By determining the governing equations of the system and simulating its behavior in various conditions, the effect of operational factors on the system...
