Development of a bio-cathode microbial fuel cell biocatalyzed by ferro/manganese-ozidizing bacteria
A biocathode microbial fuel cell biocatalyzed by ferro/manganese-oxidizing bacteria was developed.In batch-fed systems,the maximum open circuit voltage (OCV) ranged between 700 and 800 mV; the maximum cell voltage was higher than 600 mV with an external resistance of 100Ω. The maximum power density was 32 W m~(-3) MFC for batch-fed systems (20-40% Coulombic yield) and 28 W m~(-3) MFC for a continuous system with an acetate loading rate of 1.0 kg COD m~(-3) day~(-1). The results of biological oxidation and electrochemical deoxidization experiments indicated that iron and manganese co-modified electrode showed better performances than manganese modified electrode.
