The cathode-supported tubular solid oxide electrolysis cell (SOEC) fabricated by dip-coating and co-sintering techniques have been studied for high temperature steam electrolysis application. The microstructure and electrochemical performeances were investigated in both SOEC and solid oxide fuel cell (SOFC) modes. In SOFC model, the maximum power densitity reached 390.7, 311.0 and 248.3 mW cm-2 at 850, 800, and 700 °C, respectively, running with H2 (105 mL min-1) and O2 (70 mL min-1) as working gases. In SOEC mode, the results indicated that the steam ratio had a strong impact on the performance of the tubular SOEC, and it’s better to operate the tubular SOEC in high steam ratio. I-V curves and EIS results suggested that the microstructure of the tubular SOEC needs to be optimized for mass transportation.
