Fabrication of anode supported PEN for solid oxide fuel cell

【Abstract】 Fabrication process for anode supported planar PEN of intermediate temperature solid oxide fuel cell （SOFC） was introduced, in which tape casting and screen printing methods were used. Gd₂O₃ doped CeO₂ （GDC） powders were prepared by solid reaction method. Anode tape was produced by tape casting. Electrolyte and cathode were produced by screen printing. The GDC powder’s component,thermal expand coefficient, the porosity, density and microstructure of anode and electrolyte were investiga-（ted） .It was shown that an bi-layer with dense thin electrolyte film and porous anode support and with good coherency of the electrolyte film to the anode could be realized after co-sintering the green tape at 1 350℃ by optimizing the power characteristics of the starting materials in the slurry.更多还原
