Abstract

The electrochemistry of an alkaline, aqueous cell based on sodium borohydride, NaBH₄, oxidation has been studied. Cell performance has been elucidated in 3.6 cm² laboratory cells constructed with an air cathode and an anode current collector made of highly dispersed gold/platinum particles supported on high-surface area carbon silk. The number of electrons utilized per molecule of BH₄^- oxidized (approximately 6.9 out of a possible 8) implies efficient utilization of the BH₄^- oxidation. Specific energies >180 W h/kg (based on total fuel weight) and power densities >20 mW/cm² at room temperature and >60 mW/cm² at 70 °C have been obtained.
