| Description |
A direct borohydride/hydrogen peroxide fuel cell, employing
a misch-metal alloy anode and carbon-supported lead
sulfate (PbSO4/C) cathode with a Nafion®-961 membrane
electrolyte, is reported. The use of a Nafion®-961 membrane
electrolyte in the fuel cell lessens the crossover of aqueous
sodium hydroxide from the anode to cathode. Initial results
indicate that the fuel cell exhibits a maximum power density
of 10 mW cm–2 at an operating voltage of 0.77 V with an
oxidant utilization of about 80% at 25 °C. The fuel cell also
avoids the use of noble-metal catalysts. The unique combination
of sodium borohydride and hydrogen peroxide, both of
which are in aqueous from, paves theway for a convenient unitized
refueling design that is inherently compact compared to
fuel cells that use gaseous reactants. Such a fuel cell is expected
to find application in situations where anaerobic conditions
prevail, e.g., in submersible and space applications.
