Up-scaling of most promising anode formulations for the final PEM electrolysis stack

LOTERCO2.M project addresses the recycling carbon dioxide through co-electrolysis of CO2 and water by using the excess of renewable energy. The co-electrolysis process requires a CO2 reduction electrode (cathode), an oxygen evolving anode and a membrane electrolyte separating the two electrodes. The oxygen evolution reaction (OER) is a slow process affecting the overall reaction kinetics. This requires the development an efficient catalyst for oxygen evolution. Another important objective of this work package is regarding the development of non-critical raw materials-based electro-catalysts. This means that the developmental activity is mainly addressing Pt-group metal (PGM)-free catalysts
