1 Introduction Metalloporphyrins have been studied as catalysts for electrochemical CO2 reduction (eCO2R) for several decades leading to numerous reports with a broad variety of tested metal centers and ligand systems. Though most reports focus on laboratory scale testing in solution and batch type reactor cells [1-5]. To drive research into a more application orientated direction scalable flow reactors, such as zero-gap electrolyzer cells (ZGEs; Figure 1a) are needed.
