Phenylboronic Acid Modified Anodes Promote Faster Biofilm Adhesion and Increase Microbial Fuel Cell Performances

International audiencePhenylboronic acid was grafted on microbial fuel cells graphite anodes by electrochemical reduction of aryl diazonium salts. This chemical functionality enabled a faster connection of electroactive biofilms on the anodes and resulted in higher power densities and anodic catalytical current densities compared to MFCs working with unmodified electrodes
