Screen printing pastes based on organic binder systems were developed for the production of dense electrolyte layers of Y0.16Zr0.84O1.92(8YSZ) on Ni/YSZ anode substrates for anode supported solid oxide fuel cells (SOFCs). Pastes with a solid loading up to 50vol.% (86wt.%) of YSZ powder and the adequate thixotropic behaviour for screen printing could be produced. Dense layers were obtained by sintering at 1430°C and were shown to be gas tight by window and He leakage test. The electrical conductivity of the dense layers and the resulting activation energy (96–99kJmol−1) were obtained from impedance spectra in the temperature range from 250°C to 900°C. The agreement with literature values indicates that performing layers have been obtained.
