Abstract

The objectives of this work were to evaluate (i) the application of a bimetallic chalcogenide, RuxMoySez, as an oxygen reduction reaction (ORR) catalyst and (ii) the effect of the type of two anodic materials on the performance of two microbial fuel cells (MFCs). A single chamber MFC-T was built with a plexiglass cylinder, the two extreme circular faces were fitted with PEM-cathode assemblage, i.e., left and right faces. The anode consisted of 65 small triangular pieces of graphite filling the anodic chamber. A second MFC-C had a 'sandwich' arrangement anode-PEM-cathode. The cathodes were made of flexible carbon-cloth containing catalysts loading of 1mg/cm2 RuxMoySez or 0.5mg/cm 2 Pt. Power derived by cell T with cathode chalcogenide catalyst was 43% inferior to that of a similar cell with Pt although the cost of the first catalyst is significantly lower than that of Pt, i.e., 73% lower. Finally, application of graphite anode made of small triangular pieces significantly improved the performance of a MFC-T that used RuxMo ySez as a cathodic catalyst for ORR. © J. New Mat.
