Abstract
In this study, a ten-layer SOC-stack, consisting of large planar electrolyte supported cells (ESC) and CFY interconnects, was operated in both fuel cell and electrolysis modes considering steam-, co-, and CO2-electrolysis. Different gas mixtures containing H2, H2O, CO, CO2, and N2 were applied for this purpose, and an extensive analyses were performed at two temperatures, 800
