In the studies presented we proposed a new application for nanocomposite carbon films (C-Pd). These films were evaluated as an anode material for Microbial Fuel Cells (MFCs) used for electrical current generation. The results of characterization of C-Pd films composed of carbon and palladium nanograins were obtained using the Physical Vapor Deposition (PVD) method. The film obtained by this method exhibits a multiphase structure composed of fullerene nanograins, amorphous carbon and palladium nanocrystals. Raman Spectroscopy (RS) and scanning electron microscopy (SEM) are used to characterize the chemical composition, morphology and topography of these films.
We observed, for MFC with C-Pd anode, the highest electrochemical activity and maximal voltage density -458 mV (20,8 mV/cm(2)) for Proteus mirabilis, 426 mV (19,4 mV/cm(2)) for Pseudomonas aeruginosa and 652 mV (29,6 mV/cm(2)) for sewage bacteria as the microbial catalyst.
