Overcoming Salt Precipitation in CO2 Reduction Membrane Electrode Assembly Electrolyzer Enables Over 4200 Hours Stable Operation.
Alkali metal cations (AMCs) are widely recognized as critical promoters of CO2 electroreduction. Yet, salt precipitation severely undermines membrane electrode assembly (MEA) electrolyzer stability, while limited mechanistic understanding of how the interfacial cation is sustained hinders efforts to address this challe...
