“…The materials electrochemical properties were then tested by using the NiO-SDC as the anode SDC-NaCO 3 was tested using a Kittec SQUADRO device. Compressed air with flow rate of 50 mL and humidified hydrogen with a flow rate of 200 mL was passed through the cell and the cell was tested for 14 h.…”

“…SOFCs have attracted significant attention for several years, because of their high energy efficiency, excellent fuel flexibility, the growing global demand for non-polluting energy conversion systems, and a need for devices that can utilize renewable energy. [1][2][3][4] However, SOFC systems, specifically those operating above 800°C, also have some disadvantages which include longer start-up and cool down times, specialised and expensive balance of plant material, thermal management issues, and degradation of cell and stack components. Thus the reduction of SOFC operating temperature has become a key issue for the wide scale commercialization of these systems and an area of intensive research.…”

Sol-gel method was used to prepare Ce 0.8 Sm 0.2 Ir y Co 1-y O 3-ä (CSIC) (y = 0.03 and 0.04). All materials were characterized using powder X-ray powder diffraction (XRD), Raman spectroscopy, infrared (IR) spectroscopy, high resolution transmission electron microscopy (HRTEM) and scanning electron microscopy (SEM). The materials were then tested as cathodes in solid oxide fuel cell (SOFC). The XRD data showed distinct peaks for samarium-doped ceria and iridium oxide while Raman data confirmed the presence of perovskite and pyrochlore phases. Materials calcined at 1000°C had the highest power density of 0.287 W cm -2 and 0.222 W cm -2 at 500 °C for the materials with y = 0.03 and 0.04, respectively, when tested in SOFC button cells. KEYWORDSSolid oxide fuel cell, iridium oxide, samarium-doped ceria, oxides, sol-gel chemistry, Raman spectroscopy, X-ray diffraction, electrochemical properties. Experimental Methods Material SynthesisCobalt (II) acetylacetonate hydrate, (99 % purity), samarium (III) acetylacetonate hydrate (99.9 %), cerium (III) acetylacetonate hydrate, (99.9 % purity), and pluronic F-127 were purchased from Sigma-Aldrich (Pty) Ltd, South Africa. Iridium (III) acetylacetonate hydrate (98 % purity) was purchased from Alfa
