However, maintaining long\u2010term operational stability under industrially relevant high current densities remains a major challenge, primarily due to electrolyte flooding and the salt formation including carbonate and bicarbonate species, which severely compromise the performance of gas diffusion electrodes (GDEs). In this article, we present an advanced gas diffusion layer (GDL) design incorporating multiwalled carbon nanotubes (CNTs) into porous carbon\u2010based microporous layers. The resulting architecture facilitates the formation of a continuous, hydrophobic CNT\u2013polytetrafluoroethylene (PTFE) network via preferential PTFE alignment along the CNT surfaces. This hydrophobic CNT\u2013PTFE network effectively mitigates electrolyte flooding while maintaining efficient gas transport pathways. As a result, the CNT\u2010reinforced GDE demonstrated substantially enhanced CO\n                    <jats:sub>2<\/jats:sub>\n                    RR performance, sustaining a CO Faradaic efficiency above 80% for 150 h at a current density of 400 mA cm\n                    <jats:sup>\u22122<\/jats:sup>\n                    . In contrast, conventional carbon\u2010based GDEs exhibited rapid performance decay within 10 h under same conditions. These findings highlight that microstructural engineering of the GDL, via the formation of a hydrophobic CNT\u2013PTFE network, provides a robust and scalable strategy for enhancing flooding resistance and operational durability in CO\n                    <jats:sub>2<\/jats:sub>\n                    RR systems.\n
