abstract = {High-temperature solid oxide cell (SOC) stacks enable
co-electrolysis of H2O and CO2 into H2 and CO, providing an
efficient pathway toward sustainable, carbon-neutral fuel
cycles. However, SOC stacks still face degradation
challenges that hinder their broad industrial
implementation, particularly at high gas conversion ratios
and elevated current densities. Early detection of these
degradation mechanisms—using diagnostic methods such as
Total Harmonic Distortion (THD)—is essential to prevent
irreversible damage and extend stack lifetime.},
