Abstract:Fabrication process for anode supported planar PEN of intermediate temperature solid oxide fuel cell are introduced in this paper, tape casting and screen printing methods were used in the preparation progress .GDC powderwas achieved by solid reac- tion method .anode was made by tape casting .Electrolyte and cathode were made by screen printing .The GDC powder' s com- ponent and thermal expand coefficient, as well as the porosity, density and microstructure of anode and electrolyte were investi- gated .The test results have 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 can be realized after co -sintering the green tape at 1350 ℃by optimizing the power characteristics of the starting materials in the slurry .
