Direct Borohydride Fuel Cells—Current Status, Issues, and Future Directions

摘要: Fuel cells using borohydride as the fuel will be reviewed in this chapter. A direct cell (DBFC) is a device that converts chemical energy stored ion (\({\text{BH}}_{4}^{ - }\)) and an oxidant directly into electricity by redox processes. DBFC has some attractive features such high open circuit potential, low operational temperature, power density. Both electro-oxidation of \({\text{BH}}_{4}^{ }\) electro-reduction take place on large variety precious non-precious materials. DBFCs share similarities terms electrode preparation methods, system design, etc. with PEFCs, which have been developed more extensively. Therefore, chapter, technology, particularly PEFC, first to better understand materials components DBFC. Then chapter continues discuss prominent DBFC, finally points out potential future direction research.
