Electrical Conductivity in Mixed-Species Biofilms for Enhancing Energy Generation in Anaerobic Microbial Systems

Creator:: Li, Cheng
Abstract:: Further enhancement of energy generation is desired for practical application of anaerobic microbial systems such as microbial fuel cells (MFC) and anaerobic digesters (AD). A possible approach is to enhance the ability of microbial communities to transfer electron extracellularly in the form of electrical current. Critical to perform direct extracellular...

Redox Conductivity of Current-Producing Mixed Species Biofilms

Creator:: Li, Cheng, Lesnik, Keaton Larson, Fan, Yanzhen, and Liu, Hong
Abstract:: While most biological materials are insulating in nature, efficient extracellular electron transfer is a critical property of biofilms associated with microbial electrochemical systems and several microorganisms are capable of establishing conductive aggregates and biofilms. Though construction of these conductive microbial networks is an intriguing and important phenomenon in both natural...

Microbial Electrolysis Cells for the Production of Hydrogen Gas : Evaluation of Internal Resistance and Design for Scale-Up

Creator:: Miller, Andrew G.
Abstract:: Modification of microbial electrolysis cells (MECs) by altering the sizes of the anode and the cathode, or their interaction with the liquid stream affects the performance of the MEC, but it remains difficult to quantify how much each change will contribute to the overall performance. Through this study, a method...

Improved Performance of CEA Microbial Fuel Cells with Increased Reactor Size

Creator:: Fan, Yanzhen, Han, Sun-Kee, and Liu, Hong
Abstract:: The performance of an over 10 times larger microbial fuel cell (MFC) with double cloth electrode assembly (CEA) during 63 days of continuous operation demonstrates that the excellent performance of CEA-MFC can be further improved during scale-up. With a new separator material and U-shaped current collectors, the larger MFC produced...

Enhancing hydrogen production in microbial electrolysis cells through development of platinum-free cathode and improvement of reactor design

Creator:: Hu, Hongqiang
Abstract:: Microbial electrolysis provides a new approach for hydrogen generation from renewable biomass. At current stage, the most likely limiting factors for successful scale up of this technology are the large internal resistance and high fabrication cost. This dissertation presents an attempt to overcome these limitations by investigating novel microbial electrolysis...
