3. Microbial fuel cells
Two types of experiments were carried out using biofilms as catalysts. In the preliminary studies, only the cathode was covered with biofilm, whereas in the subsequent tests, both electrodes were covered with biofilm.
3.1 Microbial half-stack
As mentioned in the introduction, over the past 5 years, a number of teams have been focusing their research on catalyzing anodic reactions using bacteria, which does not solve the problem of the platinum used for the cathodic reaction. Preliminary studies carried out in collaboration with the Institute of Marine Sciences (Dr. Alfonso Mollica, CNR–ISMAR, Genoa, Italy) on a battery in an aqueous medium have demonstrated the effectiveness of biofilms formed in aerated seawater in catalyzing the cathodic oxygen reduction reaction...
