摘要: Abstract In this study, nickel-based composite anode catalysts consisting of Ni with either Pd on carbon or Pt (the ratio Ni:Pd Ni:Pt being 25:1) were prepared for use in direct borohydride fuel cells (DBFCs). Cathode used 1 mg cm −2 Pt/C electrodeposited activated cloth. The oxidants oxygen, oxygen air, acidified hydrogen peroxide. Alkaline solution sodium was as the cell. High power performance has been achieved by DBFC using non-precious metal, Ni-based anodes relatively low anodic loading (e.g., 270 mW cm NaBH 4 /O 2 cell at 60 °C, 665 mW cm /H O 60 °C). Effects temperature, oxidant, and catalyst investigated. operated about 100 h its stability recorded.
