Abstract

In the work performed citrate-nitrate synthesis of individual materials La0.9Sr0.1Sc0.9Co0.1O3 – δ and La0.9Sr0.1CoO3 – δ and composites based on these oxides. Composite materials were obtained by solid-phase mixing in different percentages of individual phases, followed by pressing and sintering. The obtained individual and composite materials were explored by X-ray phase analysis and dilatometry. The electrical conductivity of the obtained samples was studied by a four-probe direct current method depending on the temperature and composition of the gas phase. Conducted unique studies of the ability of composites to direct decomposition of ammonia directly on the electrode layer of the fuel cell.
