For the efficient electrochemical conversion of CO into valuable chemical feedstocks, a well-coordinated interaction of all electrolyzer compartments is required. In addition to the catalyst, whose role is described in detail in the part "Electrochemical CO Reduction toward Multicarbon Alcohols - The Microscopic World of Catalysts & Process Conditions" of this divided review, the general cell setups, design and manufacture of the electrodes, membranes used, and process parameters must be optimally matched. The authors' goal is to provide a comprehensive review of the current literature on how these aspects affect the overall performance of CO electrolysis. To be economically competitive as an overall process, the framework conditions, .., CO supply and reaction product treatment must also be considered. If the key indicators for current density, selectivity, cell voltage, and lifetime of a CO electrolyzer mentioned in the techno-economic consideration of this review are met, electrochemical CO reduction can make a valuable contribution to the creation of closed carbon cycles and to a sustainable energy economy.
为了将CO高效地电化学转化为有价值的化学原料，需要所有电解槽隔室之间进行良好协调的相互作用。除了在本综述“电化学CO还原为多碳醇——催化剂与工艺条件的微观世界”部分详细描述其作用的催化剂外，一般的电池设置、电极的设计与制造、所使用的膜以及工艺参数必须进行优化匹配。作者的目标是全面综述当前关于这些方面如何影响CO电解整体性能的文献。作为一个整体过程，要在经济上具有竞争力，还必须考虑框架条件、……、CO供应和反应产物处理。如果本综述的技术经济考量中提到的CO电解槽的电流密度、选择性、电池电压和寿命等关键指标能够实现，那么电化学CO还原可为建立封闭碳循环和可持续能源经济做出重要贡献。
