Abstract: This paper discusses the fabrication techniques of the compound anode/electrolyte substrate membranes of solid oxide fuel cell (SOFC) using the traditional tape casting method. The SOFC anode and electrolyte are Ni-YSZ and YSZ respectively. The techniques include the preparation of the tape casting slips and the tape casting processes. Co-sintering method was used to obtain uniform and flat SOFC porous anode-substrate compact electrolyte film. The thicknesses of the anode substrate，anode functional layer and dense electrolyte film were about 1000 µm，20 µm and 40 µm respectively. The anode porosity，electrolyte gas penetrative ratio，microstructures and thermal expansion coefficient were measured. The results indicated that SOFC anode-substrate anode/electrolyte system with well-structured and good performance could be produced by the tape casting and co-sintering method.
