Applications to Biofuel Cells and Bioreactors

This chapter starts by introducing several types of biofuel cells as an application of bioelectrocatalysis with the advantages and disadvantages. Challenging issues and outlook are also described. Photo-driven bioanodes and bio-solar cell are also introduced. Bioelectrochemical reactors are proposed as reverse reactions of biofuel cells. One of brilliant points of bioelectrocatalytic systems is the property that the systems can catalyze redox reactions bidirectionally and reversibly. The significance of this matter is discussed in view of hydrogen society.
