This thesis presents the optimization of an electrochemical CO₂ reduction cell for producing CO rich syngas under continuous flow operation. The work integrates mechanical design improvements, fluid dynamics, electrochemical performance evaluation, and economic assessments to enhance the overall efficiency and stability of the system. Seven design iterations were explored, focusing on enhancing flow uniformity, minimizing pressure drop, and optimizing the material selection to support sustainable CO₂R processes. The final design (Design 7) combined spiral flow fields, and reinforced ribs to achieve uniform flow distribution and reduced pressure drop across the electrolyte chamber. Also, dual-depth inlet seats are considered for the gas chamber to use stainless steel current collector instead of cupper tape which has the risk of degradation.
