Electrochemical characterization of bioelectronic systems

The aim of this thesis was electrochemical characterization of 24 microbial fuel cells platform for high-throughput screening of electrogenic microorganisms and comparison of measured values across all the fuel cells. In the theoretical part, there is a description of electrogenic bacteria, which are essential for current genereation in microbial fuel cells, description of microbial fuel cells and methods used for their characterization. In experimental part, there is a description of assembly process of the platform and measurement process. The result of this thesis is characterization of the platform before and after inoculation using open-circuit potential measurement, continuous current measurement, cyclic voltametry, linear sweep voltametry and electrochemical impedance spectroscopy. Thanks to this methods the values of open-circuit potencial, maximum power and internal resistance were obtained and their distribution was compared. These performed experiments verified the correct function of presented fuel cell platform
