Electrochemical CO₂ reduction is a technology under development for ensuring the production of carbon-containing products without the use of fossil raw materials. In this process, CO₂ is converted into different products depending on the selected catalyst.

The gas diffusion electrode is of crucial importance for profitable industrial operation. This circumvents the problem of otherwise impeded CO₂ solubility in aqueous electrolytes and enables direct diffusion of CO₂ to the active centers through the porous gas diffusion electrode. For the further development of the electrodes, a process for producing these gas diffusion electrodes is to be improved and the effect of various parameters on the electrodes is to be investigated.
