    Abstract

    Ni/Y2O3 stabilized ZrO2 (Ni/YSZ) cermet is a widely used hydrogen electrode for solid oxide fuel cells (SOECs), but detailed studies regarding the water splitting processes are scarce. Here we report the preliminary results on the variation of electrocatalytic activity of Ni/YSZ hydrogen electrodes as a function of operating temperature, water concentration and dc bias. The electrode activity for the water splitting reaction is strongly influenced by varying the water concentration and dc bias. The electrochemical performance for the water splitting reaction decreases with the increase of water concentration. The electrode polarization resistance increases gradually with the increase of dc bias regardless of the H2O content. The decrease of activity is particularly pronounced in the low frequency impedance process related to the H2O dissociative adsorption and diffusion processes. This study clearly demonstrates the reaction mechanism and kinetics of the H2O dissociation reaction.
