| Research Abstract |
Highly dispersed palladium and gold nanoparticles supported on bacterial cells were successfully prepared by a microbial method using the metal ion-reducing bacterium. The dried biomass-supported palladium was tested as an anode catalyst in a polymer electric membrane fuel cell for power production. The maximum power generation of the highly dispersed biomass-supported palladium particles was comparable to that of a commercial palladium catalyst. The continuous preparation system of biomass-supported palladium particles is also successfully developed. Furthermore, combination of microbial method and chemical method opened the control of the prepared particle morphology on the bacterial surface.
