The DLR’s Institute of Engineering Thermodynamics is working on the utilization of technologies of energy conversion that are efficient and gentle on resources as well as on the accelerated utilization of renewable energies. Within this context the Department of Electrochemical Energy Technology at Stuttgart, Germany, invites applicants from all over the world to work with us.
Closing the anthropogenic carbon cycle is one of the major challenges for the present mankind. Low temperature electrochemical reduction of carbon dioxide to useful chemicals can contribute to the solution of this problem by changing the role of CO2 from harmful waste to a valuable feedstock. The electrolyzer operates with renewable energy and CO2 taken from concentrated off-gas of industrial plants. One of the main challenges of this process is to bring gaseous CO2 in contact with the catalyst and the aqueous phase to maintain high space-time-yields. By applying porous gas-diffusion electrodes instead of plane electrodes the triple-phase-boundary - reaction zone - is significantly increased. One of the most important parameter for the overall electrochemical performance of these gas-diffusion electrodes is the wetting behavior as it determines the amount of accessible catalyst and transport of reactants to and products from the active sites. Additionally to the intrinsic properties of the CO2 consuming electrode the wetting can be controlled by the electrolysis process parameters. In detail the pressure ratio of the liquid electrolyte and the gaseous CO2 phase affects the wetting behavior of a gas-diffusion electrode tremendously.
