Tailoring of the Synthesis Gas composition during High Temperature Co-ElectrolysisCopyright: S. R. Foit et al.
The co-electrolysis of CO2 and H2O is a sustainable possibility for the production of Synthesis gas (short: Syngas). Syngas is a unique mixture of CO and H2, which is used as starting material for various hydrocarbons including fuels and platform chemicals. The advantage for new production concepts is that conventional infrastructure for syngas and fuels can be used without the need for fossil fuels such as coal, petroleum or natural gas. Additionally, the greenhouse gas CO2 is recycled.
Within the Kopernikus project “Power-to-X”, the aim of this PhD thesis is to investigate the processes occurring during co-electrolysis by electrochemical methods (impedance spectroscopy, current/potential-curves (I/V-curves)) and post-test characterization of the cells. Beyond that, the influence of reaction parameters (temperature, volume flow, gas composition) as well as various electrode materials will be analyzed, especially with regard to the tailoring of the syngas composition.
