Systematic screening of gas diffusion layers for high performance CO₂ electrolysis.

ABSTRACT: Certain industrially relevant performance metrics of CO₂ electrolyzers have already been approached in recent years. The energy efficiency of CO₂ electrolyzers, however, is yet to be improved, and the reasons behind performance fading must be uncovered. The performance of the electrolyzer cells is strongly affected by their components, among which the gas diffusion electrode is one of the most critical elements. To understand which parameters of the gas diffusion layers (GDLs) affect the cell performance the most, we compared commercially available GDLs in the electrochemical reduction of CO₂ to CO, under identical, fully controlled experimental conditions. By systematically screening the most frequently used GDLs and their counterparts differing in only on
