Dr. Balázs Endrődi, the leader of the Electrocatalysis Research Group at the University of Szeged, participating in the National Laboratory for Renewable Energy (NLRE) project, shares his insights.
During the NLRE project, the research group dealt with the electrochemical conversion of carbon dioxide: addressed scientific and partly technological issues. The group, in collaboration with several project partners, investigated the long-term stability of the cells, the effect of the structure of individual cell components, and implemented new operating procedures. By leveraging the expertise of partner groups, integrated systems were designed to utilise reaction products and recover unreacted materials.
The most important results of the research group:
- Achieved stable operation of CO2 electrolysis cells while simultaneously performing electrochemical glycerol oxidation at the anode.
- Demonstrated that cation management (enrichment/depletion) is the decisive factor in long-term cell stability, making dynamic performance tracking essential for optimal operation.
- Pioneered the use of machine learning to streamline and accelerate the optimization of CO2 electrolysis cell parameters.
