The solid oxide electrolysis cell (SOEC) has been receiving increasing research and attention worldwide due to its potential usage for large-scale production of hydrogen. Tape casting and lamination technique were successfully used to fabricate the NiO-YSZ hydrogen electrode substrate cermets of planar solid oxide electrolysis cell. In this paper the green tape with thickness of 350μm was prepared by tape casting and then the lamination was used to obtain the required thickness for the NiO-YSZ hydrogen electrode-supported electrolyte cermets. The rheological properties of the suspensions with NiO-YSZ and YSZ were studied, respectively. The optimal temperature and pressure of the lamination were determined, and four direction of lamination mode was used according to tape casting direction to obtain symmetrical and even hydrogen electrode-supported electrolyte after co-sintering. Pore-formers were used to increase the porosity of the hydrogen electrode. The green tape was analyzed by TG-DSC analysis, the microstructure was observed by scanning electron microscope. The electrochemical performance of unit cell was measured at 850°C.

The performance behavior of solid oxide electrolysis cell (SOEC) was investigated. Initial performance of the cell as solid oxide fuel cell (SOFC) mode at 800°C was measured as 0.15 W/cm2. The SOEC showed the stable performance during 5 hours operation at −0.15A/cm2. The power for electrolysis was increased during the first 30 minutes operation due to the increase of internal resistance of the cell. After 5 hours operation, the degradation rate of SOEC performance was about 3% due to redox reaction of hydrogen electrode.
