Abstract:

Direct NaBH4/H2O2 fuel cell is a novel type of fuel cell using liquid fuel and liquid oxidizer.NaBH4 and H2O2 are dissolved in an alkaline electrolyte (usually NaOH) and directly utilized as fuel at the anode and as oxidant at the cathode, respectively.The fuel cell operates with high voltage output, high energy conversion efficiency, and high energy density due to the generation of eight electrons by NaBH4 in the reaction.In this paper, electrode materials for the oxidation of borohydride and the reduction of hydrogen peroxide, as well as the fuel cell performance are reviewed.
