      abstract     = {While energy efficiency and conversion rates are not
                      economically competitive yet,aqueous CO2-to-CO electrolysis
                      is a promising approach for closing the carbon cycleand
                      defossilize industrial processes [1]. Ag is already
                      established as a stable andselective catalyst for this
                      process, focus is therefore on raising the
                      processperformance to a profitable level. A significant
                      share of attention is drawn towardscontinuous flowcells
                      operating with gas diffusion electrodes (GDE) [2]. This work
                      isspecifically addressing the optimization of media flow and
                      distribution in flow chambers.The internal media gaps are
                      filled with different structures and their effects on
                      theperformance are investigated. In the gas chamber the feed
                      gas distribution over theGDE was controlled by implementing
                      structures with various gas path architectures.The effect of
                      these structures on the cell voltage and the conversion of
                      CO2 to CO wasinvestigated at 100 mA/cm² in dependence of
                      the CO2 feed gas supply. Aside of othereffects, an increase
                      of the CO2 to CO conversion rate could be generated for
                      reducedCO2 supply. Next to the gas chamber, the catholyte
                      chamber was filled with a spacer,influencing the cell
                      voltage and enhancing the process stability. The
                      modifications inthe media gaps enabled in combination full
                      force closure and provided an ionic andelectric contact over
                      the full active cell area. Thus, a stackable flowcell
                      architecture wasdeveloped, demonstrated in experiments with
                      a two cell short stack.Literature:[1] CO2 Electrolysis to CO
