    Abstract:

    Typical direct borohydride fuel cells (DBFCs) use sodium borohydride (NaBH4) as the fuel and oxygen (O2) as the oxidant. However, for space and underwater applications, where O2 is not available, the gas has been replaced by hydrogen peroxide (H2O2) as a liquid oxidant. Perovskite oxides have been recently proposed as cathodes for H2O2 reduction in DBFCs, overcoming the need for expensive noble-metal electrocatalysts. In this work, perovskite-based discs are sintered in air at temperatures up to 1300 ºC to obtain ceramic samples with fractional density higher that 85 %. Eight different ceramic materials with K2NiO4 structure, namely La2NiO4, La2CuO4, La1.9Pr0.1CuO4, La1.9Sr0.1CuO4, La1.8Ce0.2NiO4, La1.9Pr0.1NiO4, La1.8Pr0.2NiO4 and La1.9Sr0.1NiO4 are tested as electrodes for H2O2 reduction reaction in alkaline media at room temperature. Cyclic voltammetry suggests that La2CuO4 and La1.8Ce0.2NiO4 present significant activity for H2O2 reduction reaction. The activity and stability of these two ceramic materials is further investigated by chronoamperometry and chronopotentiometry.
