The electrochemical reduction of CO₂ represents a promising pathway for converting captured CO₂ into value-added chemicals and fuels, contributing to the decarbonization of industrial processes. Among the possible products, C₂⁺ compounds such as ethylene and ethanol are of particular interest due to their high energy density and market value. However, the direct conversion of CO₂ to multi-carbon products remains limited by catalyst selectivity and reaction pathway constraints. This thesis investigates the optimization of a Cu-based electrochemical system for CO₂ conversion in zero-gap membrane electrode assembly (MEA) cells. A preliminary screening was conducted using Cu catalysts, evaluating the effect of binder and membrane configuration on cell performance.
