Kinetics of sodium borohydride direct oxidation and oxygen reduction in sodium hydroxide electrolyte - Part II. O-2 reduction

Original language description

In order to mimic the operation of the air-cathode in a direct borohydride alkaline fuel cell, we studied the oxygen reduction reaction (ORR) in sodium hydroxide solution containing traces of borohydride. The activity of several ORR electrocatalysts, namely carbon-supported platinum, gold, silver and manganese oxide, has been investigated using slow-scan linear voltammetry. Whereas platinum is one of the best electrocatalyst in pure sodium hydroxide, none of the classical electrocatalysts: gold, silverand platinum, exhibit sufficient selectivity towards the ORR. When BH4- is present in solution, the potential taken by electrodes using such materials is a mixed, potential, following the competition between the ORR and the NaBH4 hydrolysis and/or oxidation.
