Abstract
The article describes the results of experimental studies on the development of new active electrocatalysts for their use in the electrodes of the membrane-electrode block of a solid-oxide hydrogen-air fuel cell. Since the composition of the synthesized catalysts has a significant effect on its electrokinetic activity (electrical conductivity), the synthesis of nanoscale bimetallic catalysts of various qualitative and quantitative compositions is carried out. The choice of metal for the synthesis of the catalyst was determined by its electronic structure. The electrocatalytic activity of the developed catalysts was evaluated by studying the activity of the catalysts with respect to the decomposition of hydrogen peroxide. The developed bimetallic PVPD-Pt/ZnO/C catalysts exhibit activity with respect to the decomposition of hydrogen peroxide at 40–50 °C.
