Abstract: Microbial fuel cells are an upcoming ecological and sustainable technology to generate electricity from abundant organic residues or wastewater without the need for expensive noble-metal catalysts. Electroactive microorganisms function as biocatalysts by oxidizing organic biomass and transferring the released electrons to the anode electrode as external electron acceptor in order to sustain their bacterial metabolism. One aim of this thesis is to identify anode materials which yield high current densities. The comparison of anode materials from literature is difficult, since the studies differ in their operating conditions, measurement techniques, inoculation strategies and fuel cell constructions. Therefore, systematic and extensive anode material screenings under application-relevant steady-state conditions are presented here, using the two strains Shewanella oneidensis and Geobacter sulfurreducens.
