Self-adaptive heat management of solid oxide electrolyzer cell under fluctuating power supply

Syngas Production from CO2 and H2O via Solid-Oxide Electrolyzer Cells: Fundamentals, Materials, Degradation, Operating Conditions, and Applications

“…Based on these results, it can be inferred that there should be a sufficient minimum vapor supply to improve the electrochemical performance, CO 2 conversion and product selectivity. Sun et al 344 suggested an imported H 2 O molar fraction of 0.6 to keep the H 2 :CO ratio > 2, which is favorable for downstream chemical synthesis processes (e.g., F− T synthesis). Notably, Xie et al 131 found that for H−SOECs, the high CO 2 concentration in the feed may favor highly efficient proton utilization and suggested that the increased proton conductivity might be related to the simultaneous transportation of oxide ions in the reducing atmosphere and high hydration degree owing to the water produced via the RWGS.…”
