Performance analysis of a metal-supported intermediate-temperature solid oxide electrolysis cell

Hydrogen as an energy carrier is critical for building a zero-carbon emission society. Solid oxide electrolysis cell (SOEC) feasible technology hydrogen production with high efficiency. Currently, the durability of SOEC systems still needs to be improved and technical issues need overcome. Reducing working temperature helpful lifetime. A good design avoid delamination also very important. In this study, performance metal-supported intermediate-temperature estimated using gadolinium doped ceria Gd 0.1 Ce 0.9 O 2-δ (GDC) main electrolyte. First, mathematical model setup SOEC. The effects porosity tortuosity electrodes are analyzed. Subsequently, influences temperature, pressure, steam concentration estimated. Finally, partial oxygen pressure inside multi-layer electrolyte determined risk discussed. results indicate that increasing operation can decrease activation, concentration, ohmic overpotentials simultaneously while enhance performance. Compared conventional Ceres Power, new 10Sc1CeSZ barrier layer increase GDC close cathode such decomposition avoided. Meanwhile, anode declines reduced. Hence, beneficial
