| Research Abstract |
Fundamental and applied researches have been performed for biological fuel cell as a potent energy conversion system in future. By focusing on direct electron transfer (DET) type bioelectrocatalytic reactions with enzymes or microbes as catalysts, mechanism of the electron transfer and stability of enzyme in electric double layer have been discussed in detail. On the other hand, methods for preparation of mesoporous carbon material suitable for enzyme immobilization and DET reactions and of bio-electrodes have been presented. Based on these studies, a novel biocathode to show a steady-state current density as high as 20mA cm^<-2> under passive mode, has successfully been constructed. The performance is the best in the world.
