The 9th overseas Symposium on sturdy Oxide gas Cells: fabrics, technological know-how, and know-how was once held in January 2012 as a part of the thirty sixth overseas convention on complex Ceramics and Composites (ICACC). This symposium supplied a global discussion board for scientists, engineers, and technologists from world wide to give and speak about the newest advances in good oxide gasoline cells. This factor gains fourteen papers chosen from the symposium, providing readers a huge landscape of the present prestige of sturdy oxide gas cells know-how, in addition to rising matters and destiny instructions within the field.

Sintering of powder steel compacts is without doubt one of the simple oper ations in powder metallurgy. The necessary homes of a computing device half are received after substantial densification of the sintered fabric. even supposing the mechanical houses of the half rely on different structural components along with porosity, porosity is the most issue.

The resultant nano powder was calcined at 900 °C for 5 h. Phase analysis of the prepared powders was characterized by X-ray diffraction (X'PERT PRO Panalytical, Netherlands). 02° and a step time of 1 sec. The microstructures of the powder and samples were evaluated using HR-TEM (TECNAI G2 20, FEI), as well as SEM (EVO 50 Zeiss). 36 · Advances in Solid Oxide Fuel Cells VIII Mixed Conducting Praseodymium Cerium Gadolinium Oxide (PCGO) Pr(N0 3 ) 3 6 H 2 0 + Distilled water Ce(N0 3 ) 3 6 H 2 0 -f Distilled water Gd(N0 3 ) 3 6 H 2 0 + Distilled water Mixing the solution under vigorous stirrine at 60°C for lh Drop wise addition of 10% NH 4 OH and stirring the solution at 60°C for 5h Aging the sol for 24h followed by washing and drying at 80°C Calcination of the powder at 900°C for 5 Figure.
299 Ω-cm2 at the same temperature. Praseodymium cerium gadolinium nano-composite cathode, GDC electrolyte and NiO-GDC anode SOFC produced maximum power density of 380 mWcm"2 which indicates a promising material for the application of intermediate temperature solid oxide fuel cells. INTRODUCTION Solid oxide fuel cell (SOFC) is an electrochemical device that directly and efficiently converts chemical energy into electrical energy with fuel flexibility . Although the high operating temperature of SOFC offers several advantages over polymer electrolyte based fuel cells (PEM), it suffers high operating cost and material compatibility issues .
39 kJ mol"1 at a temperature range of 500-650 °C. 0419 S cm"1 at temperature ranging from 500 to 650 °C. 912 kJ mol"1 which is lower than that of the value, 142 kJ mol"1 reported in the literature by Hwang et al. at the same temperature range . 20O2 as electrolyte, 42 vol % NiO and 58 vol % GDC as anode and 50:50 wt. o5 02-6-GDC cathode. Polystyrene was used as a pore former in both the electrode mixtures. The electrolyte was prepared by die pressing. The 4 mg of GDC electrolyte powder was filled in a 13 mm Advances in Solid Oxide Fuel Cells VIII · 43 Mixed Conducting Praseodymium Cerium Gadolinium Oxide (PCGO) die and uniaxially pressed at 7000 PSI followed by cold iso static pressing at 40000 PSI.
