Anode Catalyst for the Direct Borohydride Fuel Cell

Direct borohydride fuel cell (DBFC) is currently attracted attentions due to its high theoretical cell voltage and power density. However, the anode catalyst of this type of battery is one of the key factors that decide the battery performance. A lot of researches have been done to improve catalytic activity and decrease the cost of the anode catalysts for DBFC in recent years. On the basis of the work principle and anode reaction mechanism of DBFC, the recent progresses of precious metal, transition metal and hydrogen storage alloy as anode catalyst for DBFC are reviewed according to perspective of catalytic performance and types. The existing problems of the anode catalyst is pointed out and the developments of the anode catalyst for DBFC are also proposed
