Abstract
Solid Oxide Cells exhibit the unique feature to be able to run in reversible operation and the capability to run with hydrocarbons. Due to the high temperature of the process, solid oxide cells exhibits very high efficiency in electrolysis mode. This makes it very attractive for Power-to-X. At the German Aerospace Center, the SOC are investigated from cell to stack level in order to characterize and understand the behavior, identify a safe operating window and extend it by identifying strategy of operation and propose alternative materials to mitigate degradation issues. At the system level, for the first time, the coupling of High Temperature Electrolysis process with heat from Concentrated Solar Power plant is investigated in order to achieve very high efficiency. Moreover, within the next two years, a research platform will be built up to investigate the co-electrolysis process at high temperature and high pressure for efficient use of CO2.
