Findings from Institute of High Current Electronics Update Understanding of Electrochemical Research (Magnetron formation of Ni/YSZ anodes of solid oxide fuel cells)

By a News Reporter-Staff News Editor at Electronics Newsweekly -- Current study results on Electrochemical Research have been published. According to news reporting originating in Tomsk, Russia, by VerticalNews journalists, research stated, "Physico-chemical and structural properties of nanocomposite NiO/ZrO2:Y2O3 (NiO/YSZ) films applied using the reactive magnetron deposition technique are studied for application as anodes of solid oxide fuel cells. The effect of oxygen consumption and magnetron power on the discharge parameters is determined to find the optimum conditions of reactive deposition."

The news reporters obtained a quote from the research from the Institute of High Current Electronics, "The conditions for deposition of NiO/YSZ films, under which the deposition rate is maximum (12 mu m/h), are found and the volume content of Ni is within the range of 40-50%. Ni-YSZ films reduced in a hydrogen atmosphere at the temperature of 800A degrees C have a nanoporous structure. However, massive nickel agglomerates are formed in the course of reduction on the film surface; their amount grows at an increase in Ni content in the film. Solid oxide fuel cells with YSZ supporting electrolyte and a LaSrMnO3 cathode are manufactured to study electrochemical properties of NiO/YSZ films."

According to the news reporters, the research concluded: "It is shown that fuel cells with a nanocomposite NiO/YSZ anode applied using a magnetron sputtering technique have the maximum power density twice higher than in the case of fuel cells with an anode formed using the high-temperature sintering technique owing to a more developed gas-anode-electrolyte three-phase boundary."
