Fuel cell is a key device for the chemical-electrical energy transformation.
Enzymatic fuel cells (EFCs) are based on the immobilization of redox enzymes on electrodes and their efficient electronic contact. In addition to a high catalyst loading, high power EFCs require the fast of electron transfer (ET) rates in order to achieve low potential/high current bioelectrocatalysis. This is especially the case at the cathode side where oxygen must be reduced into water in a 4H+/4e− process. For this purpose, high potential multicopper oxidases (MCOs) such as laccase (Lac) and bilirubin oxidase, have been widely studied at the surface of electrodes for the ability of their multicopper active site to reduce oxygen at low overpotentials. Recently, we have reported that an interface between Lac and single-walled carbon nanotubes (SWCNTs) displaying very fast electron transfer was achieved by modification with biosurfactant [1]. Furthermore, the reduction reaction of O2 was very close to the equilibrium redox potential of the O2/H2O redox couple.
Microbial fuel cells (MFCs) are promising devices that use bacteria as catalysts to oxidize organic matter and generate current. Because of their eminent merits of universality in various organic fuels, capability in treating wastewater, mild reaction conditions, and now cost, MFCs have attracted considerable interest in scientific research recently. We are investigating the MFC using mudflat at sea side, which is called “Mud battery” on our group. The mud battery can not only generate current but also reduce the BOD value in the mud [2].英語フィールド
